Introduction to Ionic Compounds
Переглядів 5616 годин тому
What do fertilizer, table salt, and poison have in common? They're all ionic compounds (ammonium nitrate, sodium chloride, and hydrogen cyanide). This video will explore: - The formation of properties ionic compounds - Writing formulas of ionic compounds - Naming ionic compounds
Joe Pug covering Mama's Eyes.
Переглядів 78Рік тому
Joe Pug reflecting on touring with Justin Townes Earle and covering his song, Mama's Eyes. Live at the Parlor Room in Northampton on 8-19-23. As a tribute to musicians we lost, Joe played Paradise by John Prine and Mama's Eyes by Justin Townes Earle. Even though the original artists are gone, their music can still be heard.

Six example reactions are carried out to demonstrate some common types of chemical reactions. 1) Synthesis of magnesium oxide 2) Decomposition of hydrogen peroxide 3) Single replacement: precipitating silver 4) Single replacement: generating hydrogen gas 5) Combustion of hydrogen gas 6) Double replacement: precipitating silver chloride
ICE Charts
Переглядів 894 роки тому
Using ICE Charts to solve for equilibrium concentrations. Key points: - (I)nitial, (C)hange, (E)quilibrium - Stoichiometric coefficients determine the ratio of change in reactant/product - If 100*Keq is less than the initial concentration, you may ignore a " x", "-x", "-2x", etc. as the change will be so small as to be negligible. Apologies for the feedback my microphone picked up! The sound is...
Rates of Reaction and Chemical Equilibrium
Переглядів 1524 роки тому
Key terms: rate of reaction, reversible reactions, dynamic chemical equilibrium. Topics: how concentration determines rates, how unequal rates leads to a shift in concentration, how equilibrium is established when concentrations are such that forward and reverse rates are equal.
Introduction to Colligative Properties
Переглядів 2284 роки тому
Why do cities salt the roads during the winter? Why can't you drink seawater? Colligative properties of solutions. hold the answer. Colligative properties are properties of a solution that depend on the concentration of the solute, but not on the identity of the solute. These include boiling point elevation, freezing point depression, osmotic pressure, and conductivity.

Partial Pressure, Density, and Effusion
Переглядів 1304 роки тому
Dalton's Law of Partial Pressure: Ptot = P1 P2 etc... Density of a Gas: D = PMW / RT Graham's Law of Relative Effusion: R1/R2 = sqrt (MW1 / MW2) Where MW = molecular weight or molar mass Summary: In many cases (such as with the Ideal Gas Law), we can treat all gases as behaving the same way. That's why that equation works for all gases we have studied. However, the density and rate of effusion ...
WNS warm-up routine
Переглядів 274 роки тому
Warm-up routine for track & field Before working out: 1) Foam roll soft tissue 2) Easy jog 3) Dynamic stretching 4) Plyometrics 10-15 minutes spent on a warm-up before working out will help prevent injury and make the training session much more productive!

Concentration as a mass solute per mass solvent
Increased yields reduce the price. All the methods in the green revolution produce diseased plants and the food we get is from those diseased plants with hardly any nutrition and is unhealthy. Profit goes to agricultural services and not to the producer while the producers land degrades.
How can I download
Great video, thank you. Your video reinforces, that if I want to learn some thing, someone on UA-cam is teaching it.
10 minutes before my chemistry exam thank you good man 😭
Thank you I need this💓👍

C block >>> A block
sup mates
huh, nice vid mate
damn im seeing everyone here
Havn't you changed from [reakt]/[product] to [product]/[reakt] between the to reaktions?
Yes! Good catch. Changes the predicted shift in the rxn.
very informative video, would recommend to fellow classmates
Damn, I wish my teacher was this cool...
10/10 love to learn chemistry! Keep at it!
great job dog keep up the good work really helping out.
Sweeeeet
Very cool Mr. Pelliccia!
Great Video!!
At the 4:35 mark, the redox reaction represented is actually Fe + CuSO4 --> Cu + FeSO4. It is not rusting. My point about the oxidation of iron is still correct.
Nice!
Great Video!
Cheers man! Helpful and straightforward vid with working out.
how did u get 17.35 I am confusion. Somebody explain
Awesome but is this going to be on the test?
Thanks!
Too fast. I couldn't understand.
