My grade went up from a 60 or 70 smth to high 80’s in three days bc of this channel 😭your explanations are the easiest & best to follow and understand!!
This made me very confident, and I learned new ways to answer questions easily due to this without even stressing myself. Pretty sure I'll definitely get 85+ on the Regents next week and pass my finals tomorrow. Thank you very much
Awesome! I love to hear that. Learning new strategies is so helpful! Going into the exam feeling confident helps a lot! I always recommend reviewing with at least 3 - 5 previous exams to be truly in excellent shape for mastery. You got this!
This is a tough, but fair exam. Aiming for mastery is a solid goal. Pushing yourself for even higher is not a bad thing. Just remember, this exam is scaled against the top scores. Typically the 15 points from 85 - 100 covers raw scores of 75 - 85 (a 10 point range). So it's more challenging at the top.
That’s awesome. I’m happy to hear the video helped! Chemistry is a challenge but it’s an exam anyone who studies for should pass! (At least) You got this!
Thank you! I’ll accept that compliment. Teaching is a hard job. I try to explain the content in a way that is easily accessible for students. We should all be met where we are and pushed to where we could be.
I have my chemistry regents tomorrow and this last minute review really helped. Thank you so much for putting in your time to help us thank you so much.
You're very welcome! I am glad it was helpful for you. I know my students appreciate having so many old exam videos to help them. Best of luck tomorrow! You got this!
never studied for chem the whole year, barely passed the semester 😭 hopefully i get some sort of basic knowledge enough to get a 50 so i can get appealed for the chem regents tmrw
Oh, goodness! Chem is certainly not an easy exam to pass without putting in the effort. I would try to review with as many old exams as you can. 3 to 5 is what I recommend for my students. If you can start to recognize the patterns in questions, you might be able to do just fine. The other thing is you really need to know the reference tables. I did a live review of the first half of the reference tables yesterday, and I’m doing another review today going through the rest. The reference tables really are the key. I mean you need to know vocabulary because vocabulary is Weaved in to every single question. But the reference tables help. A. Lot.
Thank you so much, Ive studied non-stop and I can finally answer all these questions and understand the concepts behind them before you give the explanation! Ill be sure to tune in on your livestream today as well if you are still doing that. Thank you though!
Thank you so much this was so helpful. I found myself pausing and answering questions and then if I didn’t know listening to your explanation of it and seeing all the right answers!
Title: answers with explanations 10:53 - “answer is electronegativites. You should just know that.” Wow very helpful!! Glad that YOU know the answer and didn’t feel the need to explain why the others are wrong. Even if it’s easy, why assume everyone knows it. I thought you were explaining it.
Okay, you are right. I should have explained more. I tell my students this -- electrons are involved in bonds (specifically valence electrons). Because electrons are involved in bonds, we use ELECTRONegativity to determine bond type. You look at the two atoms connected (like hydrogen and oxygen for example), find their electronegativity values on Table S and subtract the values. An answer close to 0 is nonpolar. Above 0.4 is polar Above 1.7 is ionic. However it's not an absolute. Further away from zero is more polar. And closer to zero is less polar. But for this question you didn't need to know all that. You just needed to know that you should use electronegativity. Does that help?
Chem Regents tomorrow, overall average is sitting at a 66, to pass I need like 25/50 (50%) correct for part 1 and 6/35 right on the written responses (17%) to get a combined grade of 67%, Ima do this let gooooooo
To pass the regents exam you will need to earn 50 or 51 total points. If you are talking about passing the class, that might be different. But the exam has 85 total points. You need 50 or 51 to earn a 65%
@@ImagineJenkinsThank you for responding and correcting me, one question, what is the EXACT amount of multiple choice I have to get correct and the EXACT amount of written's that I would have to get correct, keep in mind to make both numbers decently low please. If you could please word it like "you need approximately 21/50 and 12/35", I won't do so hot on either one so if you could just make both numbers decently low but to where I get 51 points/a 65% in total. THANK YOU.
@Yooooosh I tell my students to aim for 36/50 on the multiple choice and 15/35 on the written. That’s exactly 51. The more you get on the multiple choice, the more cushion you have.
@@ImagineJenkinsOhhh no that is not what I wanted to hear..I didn't think I had to get that many, thank you for letting me know and thank you for these videos they're definitely helping.
For question 77, for catalysts why does the forward reaction increase in speed? I thought catalysts does nothing in a reaction but decreases activation energy by creating an alternative pathway.
Every reaction requires enough energy and the right orientation. What a catalyst does is lower that amount of energy of energy by providing an alternate path (like a shortcut). So the reaction will happen faster because it requires less energy. Just like you could activate your phone faster if it only cost $30 instead of $100.
Catalysts increase rate because of the lower energy BUT catalysts do not affect equilibrium because both the forward and reverse reactions increase in rate.
Not in this case. They asked about why the molecule is polar. A polar bond can be described using electonegativity difference. But a polar molecule must be described in terms of the distribution of charge. Polar molecules have an unequal charge distribution. I hope that helps.
That is not on the key. Possibly you would get credit. I would just stick to saying that elements share similar chemical properties because they have the same number of valence electrons.
I have a question, for the written responses, does each question for the written response count as 1 point? So for example, if I get question 64 right but 65 wrong will I lose credit for the whole thing? Also, do you think the June 2023 test is going to be similar to this. I've reviewed this and done it and I can answer most questions here which is a good sign.
Each question is graded separately. For question 64, you can get that point if you answer it correctly. 65 will be graded on its own. So if you get 64 right but 65 wrong, you will get one point. I hope that makes sense. The exams definitely have question types that repeat. Go over at least 3-5 old exams and you will really see the question patterns. You got this!!!
There isn't a clear percentage based on units, unfortunately. Some topics frequently come up on almost every exam: isomers, isotopes, electrochemical cells, structure of an atom and experiments related to atomic theory, combined gas law calculations, acid base theories, definition of temperature, types of nuclear reactions. But, in general, the multiple choice are a fair mix of questions from atomic theory to nuclear chemistry. The written questions are less predictable. My best advice is to go through at least 3 - 5 old exams. By then, you will see a wide range of questions and will start to recognize patterns in the types of questions.
Okay, good question. The 3 is the subscript which tells how many moles of hydrogen atoms are in one mole of NH3. But, when we are comparing mole ratios in balanced equations, we always use coefficients, the big numbers in front. So NH3 has a 2 in front. That's how many moles of NH3 are in the balanced equation. Does that help?
If I could see the June 2023 exam ahead of time, that would be awesome. But I don’t see it until after you all finish it. If you study and prepare, it’s a reasonable exam. Not easy but reasonable. And review with at least 3-5 old exams, you will see the repetition in questions and you will do awesome.
I did one live stream review today and will do another live stream review on Thursday. Otherwise, check out my other exam review videos ua-cam.com/play/PLL8lWxJo-CO9Cys_0Xpo47YuBkBZoiviF.html
You could say that if the question was about why a metal conducts electricity. But this question was about an electrolyte (acid/ base/ salt) that conducts electricity when dissolved in water. So you had to say it occurs because of mobile ions or ions that the ions can move around in the solution.
You could not just say electrolyte because you had to mention ions. You could say it's an electrolyte and electrolytes have dissolved ions which makes them conduct electricity
I'll break down the name: 2-butene 2- means there is some functional group found on the second carbon but- (look at Table P) means there are four carbons connected C-C-C-C -ene (look at Table Q) means it is an alkene so there is a double bond. Where is the double bond? That's where the 2- comes in. It must be on the second carbon. All of the remaining spaces must be filled with hydrogen since it's a hydrocarbon on Table q
You can do this! Keep practicing. I tell my students to go through at least 3-5 old exams. You will start to see patterns in questions and will be exposed to a whole lot of content.
Structure always determines properties. So if they have different properties, they have to have different structures. Graphite is arranged in sheets with weaker bonds between the sheets while diamond has very strong bonds. Even though they are the same element. That's what makes them allotropes.

Wow! Thank you. I take that as a huge compliment! Good luck tomorrow. You got this.
On written questions do you not need to explain in detail exactly why you got the answer ? Cause they have a lot of lines
No, you do not need to use all the lines. You don't even need to write in sentences. You just have to answer the question.
i jus finished and a lot of the stuff in this vid we’re on the regent for example the graphite question overall it was kinda easy
Glad to hear you thought it was easy. Types of questions definitely repeat! I hope you did awesome.
For 55 could I have said the electronegativity difference is more than 0? I mean more than 0 signifies a polar bond
Not in this case. They asked about why the molecule is polar. A polar bond can be described using electonegativity difference. But a polar molecule must be described in terms of the distribution of charge. Polar molecules have an unequal charge distribution. I hope that helps.
Regents tmrrw and I regret not fully paying attention during class got 2 hours to study till the test
I hope you do way better than you think you will
For #54, could you say that they both need 4 valence electrons to become stable?
That is not on the key. Possibly you would get credit. I would just stick to saying that elements share similar chemical properties because they have the same number of valence electrons.
