In the case of your question, I believe temperature does not necessarily matter but in future questions, the temperature would need to be taken into consideration. Whether temperature matters would depend on the question.

Brenda Silva 1B

The question should mention the units that are being used whether it be bar or atm, but Dr.Lavelle did mention that for this class we would be using atm and bar interchangeably although they are not necessarily equal.

Brenda Silva 1B

I believe that we would be tested on the content of acids and bases learned in 14B but the content does build on what we learned in 14A so we would just need to have an overall general idea of what was covered in 14A.

Brenda Silva 1B

We would need to include H2O in the ICE table if it is a gas but would not be included if it's in a liquid state.

Brenda Silva 1B

P=pressure, V=volume, n=number of moles, R= gas constant, and T= temperature

Brenda Silva 1B

Yes, Q and K are both the ratio of [products]/ [reactants] and the only difference is that K is used when equilibrium has been reached and Q is used anytime the reaction is occurring.

Brenda Silva 1B

We would need to write the temperature in Kelvin, therefore when we are given the temperature in Celsius we would have to convert it to Kelvin by adding 273.15 to the temperature.

Brenda Silva 1B

The syllabus does not mention much how many points each question on the exams would be worth but as the previous posts say, the questions may be worth fewer points than the exams taken in 14A.

I want to improve my time-management skills, to have more time for self-care, and not feel behind in my classes while taking some time off for myself.

Brenda Silva 1B

I tend to review the concepts we learned each week by completing random textbook problems that we were assigned that week. Completing the textbook problems is helpful as I can see what topics I need to spend more time studying. I also find the UA and step-up sessions extremely helpful because I have...

Brenda Silva 1B

I believe they would be using the textbook problems to construct the final which is why there is an emphasis on studying by working on the textbook problems. Good luck studying!

Brenda Silva 1B

I do not believe all the questions would come from the textbook but a good majority will which is why they are encouraging us to look over the textbook problems when studying. Good luck studying!

Brenda Silva 1B

I have been watching the lectures on the content I am still having trouble with and going to that section of the textbook to complete the practice problems. The review sessions have also been very helpful as they give you practice problems to work on. Take advantage of all the resources Dr.Lavelle i...

Brenda Silva 1B

Thank you for this! Good luck to everyone!

Brenda Silva 1B

The final would be cumulative but there would be more questions on the topics we spent the most time on. It is expected that there would be more questions on the quantum world because we spent multiple days learning about it.

Brenda Silva 1B

The final would be similar to the last two midterms, all questions would be multiple choice.

Brenda Silva 1B

Most likely the tests would be a similar format to the midterms, therefore some questions would be like the textbook problems.

Brenda Silva 1B

The review sessions and the UA workshops would be helpful for the final. Dr. Lavelle sent an email with times for all the review sessions, step-up sessions, and other resources to help us for the final.

Brenda Silva 1B

Now that finals are approaching I feel more stressed and overwhelmed. It is difficult to stay on top of all my classes especially chemistry. Good luck to everyone on the final!

Brenda Silva 1B

The shape of the molecule and the difference in dipoles are also important to figure out whether a molecule is polar or non-polar. If the dipole forces cancel out then the molecule is non-polar.

Brenda Silva 1B

I do not think there are past final exams that we could study but the textbook problems have been helpful for the midterms.

Brenda Silva 1B

Our final would be on Sunday, December 13th from 11:30 am to 1 pm.

Brenda Silva 1B

You should email your TA to review the answers to the second midterm. Some TA's would review your answers during their office hours while other TA's prefer if you make an appointment with them.

Brenda Silva 1B

I am worried about my grade but we still have a few weeks to continue studying for the final. Good luck to everyone on their final!

Brenda Silva 1B

Finals week begins after week 10 and there are no classes during finals week but there would still be classes and discussion during week 10. The final for this class would be on Sunday, December 13.

Brenda Silva 1B

Doing practice problems from the textbook are very helpful. I tend to focus more of my time on the concepts I do not fully understand and complete the practice problems from there.

Brenda Silva 1B

I have spent more time organizing my notes and highlighting the topics I still need to focus more time on. I then tend to look for the topic in the textbook and work over a couple of problems until I have a greater understanding. If I have a difficult time understanding I tend to read over the chapt...

Brenda Silva 1B

If you are not able to get Chem 14BL during your second pass it is totally fine to take it the following quarter. You do not need to take the class at the same time.

Brenda Silva 1B

For the final, I would continue to do textbook practice problems as they have been very helpful for the midterms. I would also recommend attending the workshop sessions to get more practice on different problems. Good luck to everyone studying!

Brenda Silva 1B

I do not think we would be having a lecture on Friday because our school calendar does say there is no school on the 26th and 27th.

Brenda Silva 1B

This midterm had a few confusing questions but we are all done! Congrats to everyone for finishing!

Brenda Silva 1B

I would recommend watching Money Heist and Supernatural which are both on Netflix.

Brenda Silva 1B

There was a couple of questions that were tricky but overall I think it went well. Now that I have taken the midterm I am taking time to myself by watching Netflix.

Brenda Silva 1B

Hi! It is easy to get distracted at home and it is difficult to stay focus. What I tend to do is to try and find an isolated location where I would not get distracted by my family. I also take breaks once in a while because it is difficult to stay focus for long periods of time.

Brenda Silva 1B

I took chem my sophomore year in high school and some of the topics I have seen before while others are completely new. I really appreciate how Dr. Lavelle is explaining all concepts as if they were new for everyone.

Brenda Silva 1B

I would be studying from the textbook since it was helpful for the first midterm. In order to get more practice, I would also be studying the sapling questions.

Brenda Silva 1B

Electronegativity does affect bond length because if the electronegativity is high the atoms will be pulling the electrons with more force, moving the electrons closer, leading to a shorter bond length.

Brenda Silva 1B

Continue to study and just know that you have been studying for it the whole quarter. Take breaks when you need them and do breathing exercises before the exam to go in a bit more calm.

Brenda Silva 1B

I don't think Dr.Lavelle mentioned anything about the midterm being curved because like people said above there were partial points given and the class is based off on points.

Brenda Silva 1B

The modules were very helpful for the first midterm but I don't think Dr. Lavelle would be posting new ones.

Brenda Silva 1B

Formal charge is used to determine the most stable Lewis structure, we want a structure that has zero charge or near zero charge as it is most stable.

Brenda Silva 1B

In most cases, the v that is italicized would be the frequency and the normal v would be velocity but it is best to look at the units being used.

Brenda Silva 1B

The Audio-Visuals were extremely helpful for the midterm, hopefully Dr. Lavelle does post more.

Brenda Silva 1B

I enjoy watching Netflix, listening to music, and baking to relax.

Brenda Silva 1B

Based on what we have learned so far, c will be the speed of light constant (2.998x10^8 m/s).

Brenda Silva 1B

It would be best to convert nm to m because the units for velocity are m/s therefore you would have the same units when solving the problems.

Brenda Silva 1B

I find the audio visual modules very helpful as they introduce you to the concepts and you have a better understanding when watching the lectures. The post-assessments are also very helpful as they give you and opportunity to put into practice the concepts you just learned. The problems also allow y...

Brenda Silva 1B

This is very helpful! Thank you so much!

Brenda Silva 1B

mmol is the abbreviation of millimole, 1mmol= 0.001mol

Brenda Silva 1B

The midterm would be closed notes and would be multiple choice. We would be taking it next week during our discussion section.

Brenda Silva 1B

It is helpful to complete some of the textbook problems ahead of time to have an idea about what would be covered in lecture. Also take advantage of the workshops and the modules on the website. The modules and the pre/post-assessments cover the basics of the concept and then you could put your unde...

Brenda Silva 1B

I believe we would be given the equations and constants on the test but it would be safe to have an overall idea of them in case they do not. But most likely they would provide us all the information we would need to solve the problems.

Brenda Silva 1B

Protons and neutrons have about the same mass while electrons have a smaller mass. The atomic mass of an element is dependent on the weight of the protons and neutrons because electrons have little to no effect on the mass.

Brenda Silva 1B

Yes, you should used a scientific or graphing calculator to solve those problems. In order to get an accurate result try putting the entire problem in the calculator and use parenthesis correctly. It is important to place the parenthesis in the correct place, to avoid getting the wrong result.

Brenda Silva 1B

Electrons would not stay in their excited state for a long period of time. They would have to return to their ground state.

Brenda Silva 1B

When solving for wavelength it would most likely specify what format the answer should be in. If you are not told whether it has to be in meters or nanometers, it should be fine to have your answer in meters.

Brenda Silva 1B

When solving a problem with multiple steps, such as a two step problem, try using the exact values throughout your calculations and only round your final answer, this would allow you to have an accurate result.

Brenda Silva 1B

In one of the lectures Dr. Lavelle did mention that for stoichiometric coefficients it is best to use whole numbers.

Brenda Silva 1B

Mostly likely the periodic table would be given to us during the test but it would be helpful if you know the most common elements and start reviewing the rest of them.

Brenda Silva 1B

The molecular formula can be the same as the empirical formula, just keep in mind that the empirical formula is a ratio of the molecular formula therefore it could not be larger than the molecular formula.

Brenda Silva 1B

The empirical formula could not be larger than the molecular formula because the empirical formula is a ratio of the molecular formula. Therefore, it could only be smaller or the same as the molecular formula.
