CHEMISTRY COMMUNITY

Bryan Le 2K

It is due Sunday, March 14 at midnight!

Bryan Le 2K

When I feel burnt out, I generally watch a show or talk with my friends to get my mind off school for a little. I just got to make sure I don't spend too much time relaxing.

Bryan Le 2K

I am taking chem 14c!

Bryan Le 2K

N is the number of electrons transfers. You can find them from the half reactions. They should be the same number.

Bryan Le 2K

I believe it is worth 4 points!

Bryan Le 2K

This quarter has been so busy for me. I can't wait until spring break and finally relax!

Bryan Le 2K

I enjoy doing chemical equilibrium problems!

Bryan Le 2K

Only gases apply to this law! Make sure to check the reaction. I make this mistake a lot on exams and practice problems.

Bryan Le 2K

I am currently a sophomore and I really miss having late nights with my friends.

Bryan Le 2K

Thanks for the reminder!! I totally forgot about this.

Bryan Le 2K

I think that the final will have more of topics covered after midterm 2 with a smaller amount covering the topics previously. I could be wrong though.

Bryan Le 2K

Yea, it is possible but it will take a very long time.

Bryan Le 2K

Organic Chemistry Tutor has been a big help to me!

Bryan Le 2K

The review session is on Saturday while the Final will be on Sunday at 9:30 am.

Bryan Le 2K

I would recommend going over all the topics and getting a good understanding of each topic. A good indicator of your understanding could be if you could explain/teach this topic to someone else. I would also recommend going the practice problems several times!

Bryan Le 2K

I use the acronym OIL RIG which stands for "Oxidation is loss, reduction is gain."

Bryan Le 2K

When you increase the temperature, this results in more collisions between particles. This will lead to an increase in K.

Bryan Le 2K

I love poke and Korean Fried Chicken!

Bryan Le 2K

The anode is always on the left while the cathode is always going to be on the right. This order is really important to have for cell diagrams.

Bryan Le 2K

I am feeling stressed/nervous about the final. Based on Midterm 2, I realized I should have a better understanding of the material conceptually.

Bryan Le 2K

In this equation, n represents the number of moles of electrons.

Bryan Le 2K

I plan to watch some introductory videos on ochem on youtube and refer to friends who taken the course for help.

Bryan Le 2K

Cell potential is not a state function because the path it takes to reach the final value matters.

Bryan Le 2K

I love poke and Korean fried chicken!!

Bryan Le 2K

I will be taking psych 130 and chem 14c so far. I am not sure what my last class would be yet.

Bryan Le 2K

This weekend I took a break and caught up on some shows as well as catch up with some of my friends.

Bryan Le 2K

I would suggest trying to get a blank a piece of paper and write out everything you know about the specific topic. From there, you can see what sections you really need help on. I hope you excel in this class! Good luck!

Bryan Le 2K

Thank you! I wish you all a Happy Valentine's Day as well. I hope everyone has a restful weekend!

Bryan Le 2K

You should use Kelvin and not Celcius since the R constant is in terms of K.

Bryan Le 2K

I am currently rewatching Friends!

Bryan Le 2K

I am hopefully going to enroll in chem 14c, physics 5c and psych 130 or 135.

Bryan Le 2K

You can use either 273 or 273.15. Using 273.15 gets you a more accurate answer, but your answer at the end is still roughly the same.

Bryan Le 2K

Thanks a lot for sharing this with us! This is a great way to look at mistakes. I feel better reading this.

Bryan Le 2K

In my experience, the best way to figure out what R constant to use is to look at the units that I am given. From there, I pick the appropriate R constant to matches with the units.

Bryan Le 2K

For me, I generally read the book and make an outline of the topics. From there, I do the assigned practice problems several times until I can do it by myself without any help.

Bryan Le 2K

The Bucs are going to win!

Bryan Le 2K

Heat capacities should be positive because it is the amount of heat needed to increase the temperature of the volume by 1 degree.

Bryan Le 2K

Yes, their standard enthalpy of formation for diatomic molecules will be zero. The value is zero because these molecules are in their most stable state at standard condition.

Bryan Le 2K

To calculate the K for a reverse reaction, you would take the 1/K of the forward reaction because the numerator and reactants are now switched.

Bryan Le 2K

Thanks for the positivity! I decided to take a break from all my work and just treat myself to some Netflix and games after studying a lot for this midterm.

Bryan Le 2K

Enthalpy is a state function. This means that it doesn't relate to the path that it takes to reach the final values. It only corresponds with the initial and final values.

Bryan Le 2K

Delta H is positive when the reaction is endothermic because heat is absorbed while delta H is negative when the reaction is exothermic because heat is released.

Bryan Le 2K

When looking at changes in pressures in relation to the chemical reaction, you would like at the moles of the gases only.

Bryan Le 2K

I generally like to listen to chill music. Some artists I listen to are Lauv, Jeremy Zucker and Rex Orange County.

Bryan Le 2K

You can use any type of calculator for the exam!

Bryan Le 2K

You include H2O in the ice table only if it is a gas. If it is a liquid then we wouldn't include it.

Bryan Le 2K

A phase change is when the state of matter of an substance changes between solid, liquid, or gas. For example, a liquid changing to a gas is considered a phase change.

Bryan Le 2K

Ka is used when H30+ is formed while kb is used when OH- is used. Ka is for acid dissociation and kb is for base dissociation.

Bryan Le 2K

X is negligible when the value is smaller than 10^ -4.

Bryan Le 2K

When I am stressed from school, I like to lay down and either watch some shows or listen to music. Often times, I would just take a walk around my house or talk to my siblings.

Bryan Le 2K

The units for temperature should be in Kelvin.

Bryan Le 2K

Something I like to do when I am studying is to write everything I know about a topic on a piece of paper. From there, I would figure which topics I really need to focus on. I also recommend to do a lot of practice problems to help prepare you for the exam. In doing so, you would be more aware of th...

Bryan Le 2K

Yea, the ICE table can be used for both partial pressure and concentration. Using these table, one could find many quantities such as the K constant or initial concentration of something.

Bryan Le 2K

My go-to comfort movie would have to be Avengers Endgame or Thor Ragnarok. Other than these, I really enjoy watching Disney movies.

Bryan Le 2K

Hi, the units for temperature should be in Kelvin.

Bryan Le 2K

Yes! Q is used when the system hasn't reach equilibrium yet while K is used when the system has reach equilibrium.

Bryan Le 2K

Hi! I like to watch Netflix or play video games with my friends. Sometimes, I also enjoy playing board games with my family.

Bryan Le 2K

Why did the attacking army use acid?
To neutralize their base.

Bryan Le 2K

I believe you should attend as many sessions as you can. They can viewed as a great way to clarify information or review material.
