We say hydrogen is electropositive in nature and loses electron to gain positive charge to become a cation And on the other hand we also know that hydrogen atomic number is 1 and if the hydrogen atomic number is 1 that means it has only one electron in its K shell If that electron is losen by that particular atom of hydrogen Then there will be no left out electron in the atom then how could that atom particularly exist?
A hydrogen atom has one proton in its nucleus and one electron in its only shell (the K shell). Its atomic number is 1. When a hydrogen atom loses its single electron, it becomes a hydrogen cation (H⁺). This cation has no electrons left, but it still contains its proton, which makes it a positively charged ion. The hydrogen cation (H⁺) is stable in certain environments. In solutions, it often associates with other species, typically forming hydronium ions (H₃O⁺) in water, where it combines with water molecules
Gypsum consists 2H2O To convert Gypsum to Plaster Of Paris , we heat it at 100 degree Celsius, We have studied that , on heating water at 100 degree Celsius, there is an occurrence of latent heat of vapourisation So why the product comes out water , why not steam
Here’s why the product comes out as water (or anhydrous) rather than steam: Dehydration Process: Upon heating, gypsum loses two water molecules to form plaster of Paris . This process involves the removal of water bound within the crystal structure rather than vaporizing it into steam. Temperature and Pressure: At atmospheric pressure, the boiling point of water is 100 degrees Celsius, but the dehydration of gypsum occurs at this temperature, enabling the bound water to be released as liquid water rather than turning into steam. The latent heat of vaporization is significant when converting liquid water to steam. However, since we’re dealing with bound water in a solid crystal lattice, it’s released as liquid during the transition to plaster of Paris. State of the Water: The water in gypsum is not in free form. It is part of the structure of the mineral, so when heat is applied, it is released as water molecules instead of evolving as steam.

Scientists: Jaise "einsteinium" (Albert Einstein ke naam par). IUPAC Approval: Nue naming ko IUPAC se approval milta hai, jo ensure karta hai ki naam standard aur internationally recognized ho. Element Symbol: Jab element ka naam finalize ho jata hai, tab uska symbol bhi diya jata hai. Ye symbol 1 ya 2 letters ka hota hai, jismein pehla letter hamesha capital hota hai. Example Oganesson (Og): Atomic number 118. Isse "oganesson" naam diya gaya hai, jo scientist Yuri Oganessian ke naam par hai.

The conductivity of an electrolyte solution depends on its concentration, the presence of ions, and the type of ions produced when dissolved in water. Both acidic and basic electrolytes can conduct electricity, but the conductivity varies based on their dissociation in water. Acidic Electrolytes Definition: Acidic electrolytes contain acids that dissociate in water to produce hydrogen ions (H⁺) and other ions (e.g., sulfate ions from sulfuric acid, chloride ions from hydrochloric acid). Conductivity: Strong acids (like hydrochloric acid, sulfuric acid, and nitric acid) fully dissociate in solution, producing a high concentration of ions, which enhances conductivity. Basic Electrolytes Definition: Basic electrolytes contain bases that dissociate in water to produce hydroxide ions (OH⁻) and other ions (e.g., sodium ions from sodium hydroxide). Conductivity: Strong bases (like sodium hydroxide or potassium hydroxide) also fully dissociate in solution, yielding a high concentration of ions, leading to good conductivity. Comparison Strong Acids vs. Strong Bases: Generally, strong acids and strong bases have similar degrees of conductivity when fully dissociated, assuming the same molar concentration. However, the absolute conductivity may differ based on the specific electrolytes involved. Weak Acids and Bases: Weak acids (like acetic acid) do not fully dissociate in water, resulting in lower conductivity compared to strong acids and strong bases.
Friedrich Wöhler is known for his landmark work in organic chemistry that debunked the idea that organic compounds could only be derived from living organisms. His synthesis of urea from ammonium cyanate in 1828 is a famous example. While Wöhler's work was groundbreaking, converting a molecular formula like ( C_2H_4O ) into different compounds is a common practice in organic synthesis. Isomers of C₂H₄O The molecular formula ( C_2H_4O ) corresponds to several structural isomers, including: Ethylene Oxide (Oxirane): A cyclic ether. Acetaldehyde (Ethanal): An aldehyde. Ethanol (Ethyl Alcohol): An alcohol. Conversion of C₂H₄O Isomers Although Wöhler's synthesis isn't directly applicable to every compound, the principles of organic synthesis today allow chemists to convert one isomer of ( C_2H_4O ) into another through various reactions. Here are a few methods to interconvert isomers or convert them into different compounds: Hydrogenation: For example, converting Ethylene Oxide into Ethanol through the addition of hydrogen. [ \text{C}_2\text{H}_4\text{O} + \text{H}_2 ightarrow \text{C}_2\text{H}_6\text{O} ] Oxidation and Reduction: Acetaldehyde can be oxidized to acetic acid and reduced back to ethanol, or vice versa. Oxidation of Ethanol to Acetaldehyde: [ \text{C}_2\text{H}_6\text{O} \xrightarrow{\text{Oxidizing Agent}} \text{C}_2\text{H}_4\text{O} + \text{H}_2\text{O} ] Rearrangements: Isomers can also be formed through rearrangement reactions, where the structural framework of a compound is altered without changing the molecular formula. Example of Interconversion For example, if you wanted to convert ethanol to acetaldehyde: You could conduct oxidation using an oxidizing agent like potassium dichromate (( K_2Cr_2O_7 )) in acidic solution. In summary, while Wöhler's historical synthesis is significant, modern organic chemistry employs a variety of reactions to interconvert compounds with the same molecular formula, such as ( C_2H_4O ), into different isomers using techniques like hydrogenation, oxidation, and rearrangement.

hard and Soft Water are terms used to describe the mineral content of water, particularly its calcium and magnesium ion concentrations. Hard water contains a high concentration of dissolved minerals, primarily calcium (Ca²⁺) and magnesium (Mg²⁺) ions. Hardness originates from the natural dissolution of minerals in the soil and rocks (such as limestone and chalk) as water moves through them Effects: Hard water can cause scale buildup in pipes, boilers, and water heaters, reducing efficiency and lifespan of appliances. It may also lead to soap scum formation, making it difficult to produce lather when using soap. Soft water is water that contains low concentrations of calcium and magnesium ions and is typically treated to remove these minerals. Soft water may occur naturally in areas with little limestone and higher rainfall or may be created through water treatment methods like ion exchange processes. Effects: Soft water doesn't cause scaling and is easier to use for soaps and detergents, producing more lather and cleaning effectively. It can be more corrosive to plumbing systems and may leach metals like lead or copper from pipes if not properly managed. Uses: Softened water is preferred in household applications, like laundering, dishwashing, and bathing, as it helps reduce detergent use and prevent hard water deposits on dishes and glassware.

Sodium lauryl sulfate (SLS) is a synthetic organic compound that is widely used as a surfactant and detergent. NaC12H25SO4 Structure: SLS consists of a long hydrophobic hydrocarbon chain (the lauryl group) and a hydrophilic sulfate group, which gives it surfactant properties that allow it to reduce surface tension. Uses: Personal Care Products: It is commonly found in shampoos, toothpastes, bubble baths, and body washes. It helps to create lather and remove dirt and grease. Household Cleaners: SLS is also used in various household cleaning products and detergents due to its effective cleaning properties. Industrial Applications: It is utilized in certain laboratory applications, oil recovery, and as an emulsifier. Commercial Availability: Sodium lauryl sulfate is readily available and is often used interchangeably with sodium dodecyl sulfate (SDS), though there are minor differences in their structures and properties. Safety and Irritation: While SLS is effective in cleansing, it can sometimes cause skin irritation or allergic reactions, especially in sensitive individuals. Therefore, it’s essential to use it within the recommended concentrations in cosmetic and personal care products.
Dissociation refers to the process by which a compound separates into its individual components, typically ions or molecules, when it is dissolved in a solvent, such as water.

@@digvijay2180 Methanol (wood alcohol) is a toxic substance that can have severe effects on the central nervous system, including the optic nerve. When methanol is ingested, it is metabolized in the body primarily to formaldehyde and then to formic acid. Both of these metabolites are highly toxic and can lead to various health issues, including those affecting vision. Effects of Methanol on the Optic Nerve: Optic Nerve Damage: Methanol toxicity can lead to damage of the optic nerve due to the direct effects of its metabolites, primarily formic acid. This can result in optic neuritis, which is inflammation of the optic nerve, causing vision impairment. Visual Disturbances: Individuals exposed to methanol may experience a variety of visual disturbances. Symptoms can include blurred vision, decreased visual acuity, and even complete loss of vision in severe cases (often referred to as "methanol blindness"). Retinal Toxicity: Methanol and its metabolites can also be toxic to the retina, further complicating visual function. Damage to the retina can lead to specific types of visual impairment and contribute to the overall decline in vision. Mechanism of Toxicity: The mechanism involves disrupting cellular metabolism and producing reactive oxygen species, which can lead to neuronal cell death. Additionally, the accumulation of formic acid can cause metabolic acidosis, which may exacerbate the damage to the optic nerve and other areas of the central nervous system. Delayed Symptoms: One crucial point is that symptoms of methanol poisoning can be delayed, sometimes appearing 24 hours or more after ingestion. This makes early diagnosis and treatment challenging.
Hetero atoms, or heteroatoms, are atoms that are different from carbon (C) and hydrogen (H) found in organic compounds. They are often found in the structure of organic molecules, contributing to the chemical diversity, reactivity, and properties of those compounds. Common Heteroatoms: Oxygen (O): Present in alcohols, ethers, carbonyls, and carboxylic acids. Nitrogen (N): Found in amines, amides, and nitro compounds. Sulfur (S): Found in thiols, thioesters, and sulfonic acids. Phosphorus (P): Commonly found in organophosphates and nucleotides. Halogens (F, Cl, Br, I): Often present in alkyl halides and various functional groups.
Sulfuric acid is often referred to as the "king of chemicals" due to its extensive industrial use and fundamental role in chemical processes. Here are several reasons why it holds this title: Production Volume: Sulfuric acid is one of the most widely produced and used industrial chemicals in the world. Its production volume is often considered an indicator of a country's industrial strength and development. Versatility: It is used in a wide range of applications, including the production of fertilizers (such as superphosphate and ammonium sulfate), petroleum refining, wastewater processing, and chemical synthesis. Role in Manufacturing: Sulfuric acid is crucial in the production of numerous chemicals, including hydrochloric acid, nitric acid, and various dyes and detergents. It also plays a vital role in the manufacturing of lead-acid batteries used in vehicles. Catalyst and Reactant: It serves as both a reactant and a catalyst in many chemical reactions, making it vital for various synthetic pathways. Economic Significance: The economic significance of sulfuric acid is immense, given that it underpins numerous sectors such as agriculture, manufacturing, and pharmaceuticals.
Isotopes are atoms of the same element that have the same number of protons (same atomic number) but different numbers of neutrons. This results in different mass numbers. Example: Carbon-12 and Carbon-14 are isotopes of carbon. Both have 6 protons but differ in their neutron count (Carbon-12 has 6 neutrons, while Carbon-14 has 8 neutrons). Isobars are atoms of different elements that have the same mass number but different numbers of protons (different atomic numbers). This means that isobars have different elemental identities but contain the same total number of nucleons (protons + neutrons). Example: Argon-40 and Calcium-40 are isobars. Both have a mass number of 40, but argon has 18 protons and calcium has 20 protons.

@@Velex__ Canal rays, also known as "positive rays," are streams of positively charged particles observed in certain types of gas discharge tubes. They were discovered by the German physicist Eugen Goldstein in the late 19th century Canal rays are produced when a high voltage is applied across two electrodes in a low-pressure gas-filled tube. The metal cathode emits electrons, which collide with gas atoms, ionizing some of them and allowing positive ions to be formed. The particles that make up canal rays are positively charged ions. These ions can include various types of atoms, depending on the gas used in the tube.
Lim also known as calcium light, is a type of stage lighting that was used in the 19th century.

Sir what iss meaning of dissociate
Dissociation refers to the process by which a compound separates into its individual components, typically ions or molecules, when it is dissolved in a solvent, such as water.
ye syllabus se hat nhi gaya iss saal ke 10th ke liye??
this video explains the elements and their placement in periodic table that serves as the basics for class 9, 10 , 11, 12 IITJEE and NEET, this is not a chapter for class 10, this is to create understanding which is definitely required for other topics where ever elements , their properties and behaviour is discussed, ( you are right as a proper chapter it is not in CBSE 10 only ) other classes have it as a proper chapter as well including 10th class ICSE

How Methanol affects optic nerve
@@digvijay2180 Methanol (wood alcohol) is a toxic substance that can have severe effects on the central nervous system, including the optic nerve. When methanol is ingested, it is metabolized in the body primarily to formaldehyde and then to formic acid. Both of these metabolites are highly toxic and can lead to various health issues, including those affecting vision.
Effects of Methanol on the Optic Nerve:
Optic Nerve Damage: Methanol toxicity can lead to damage of the optic nerve due to the direct effects of its metabolites, primarily formic acid. This can result in optic neuritis, which is inflammation of the optic nerve, causing vision impairment.
Visual Disturbances: Individuals exposed to methanol may experience a variety of visual disturbances. Symptoms can include blurred vision, decreased visual acuity, and even complete loss of vision in severe cases (often referred to as "methanol blindness").
Retinal Toxicity: Methanol and its metabolites can also be toxic to the retina, further complicating visual function. Damage to the retina can lead to specific types of visual impairment and contribute to the overall decline in vision.
Mechanism of Toxicity: The mechanism involves disrupting cellular metabolism and producing reactive oxygen species, which can lead to neuronal cell death. Additionally, the accumulation of formic acid can cause metabolic acidosis, which may exacerbate the damage to the optic nerve and other areas of the central nervous system.
Delayed Symptoms: One crucial point is that symptoms of methanol poisoning can be delayed, sometimes appearing 24 hours or more after ingestion. This makes early diagnosis and treatment challenging.

Common Heteroatoms:
Oxygen (O): Present in alcohols, ethers, carbonyls, and carboxylic acids.
Nitrogen (N): Found in amines, amides, and nitro compounds.
Sulfur (S): Found in thiols, thioesters, and sulfonic acids.
Phosphorus (P): Commonly found in organophosphates and nucleotides.
Halogens (F, Cl, Br, I): Often present in alkyl halides and various functional groups.
Sir why sulphuric acid is called the king of chemicals?
Sulfuric acid is often referred to as the "king of chemicals" due to its extensive industrial use and fundamental role in chemical processes. Here are several reasons why it holds this title:

Sir isotope or isobar kya hota ha me prageet
Isotopes are atoms of the same element that have the same number of protons (same atomic number) but different numbers of neutrons. This results in different mass numbers.
Example: Carbon-12 and Carbon-14 are isotopes of carbon. Both have 6 protons but differ in their neutron count (Carbon-12 has 6 neutrons, while Carbon-14 has 8 neutrons).
Isobars are atoms of different elements that have the same mass number but different numbers of protons (different atomic numbers). This means that isobars have different elemental identities but contain the same total number of nucleons (protons + neutrons).
Example: Argon-40 and Calcium-40 are isobars. Both have a mass number of 40, but argon has 18 protons and calcium has 20 protons.

Sir canal rays kya hoti ha
@@Velex__ Canal rays, also known as "positive rays," are streams of positively charged particles observed in certain types of gas discharge tubes. They were discovered by the German physicist Eugen Goldstein in the late 19th century
Canal rays are produced when a high voltage is applied across two electrodes in a low-pressure gas-filled tube. The metal cathode emits electrons, which collide with gas atoms, ionizing some of them and allowing positive ions to be formed.
The particles that make up canal rays are positively charged ions. These ions can include various types of atoms, depending on the gas used in the tube.
Lime-light???????????????
Lim also known as calcium light, is a type of stage lighting that was used in the 19th century. It works by heating a cylinder of quicklime (calcium oxide, CaO to a very high temperature, causing it to emit an intense white light
Heating Quicklime: A block of quicklime is heated by an oxyhydrogen flame, which is a flame produced by burning a mixture of oxygen and hydrogen gas. The intense heat causes the quicklime to emit a bright, white light.
Light Emission: The light produced is very bright and has a slightly greenish tint. This luminescence is due to the incandescence of the heated lime.

Arrehenius acid ????
And base tooo
An Arrhenius acid is a substance that increases the concentration of hydrogen ions H+ in aqueous solution.This definition is part of the theory proposed by the Swedish chemist Svante Arrhenius in the late 19th century.
When an Arrhenius acid is dissolved in water, it dissociates to produce H+ ions. For example, hydrochloric acid dissociates in water .Sulfuric acid.,Nitric acid, Acetic acid, Arrhenius acids are typically characterized by a sour taste (in dilute solutions), the ability to turn blue litmus paper red, and their reactivity with bases to produce salt and water (neutralization reactions).
