When trying to find the rate law of a table with different experiments, how do you know which experiments to use?

Raquel Rodriguez

How are we able to determine the intermediate of a chemical reaction when finding the rate law?

Raquel Rodriguez

Do we need to know how to recognize the different molecularity in different reactions for the final?

Raquel Rodriguez

Oh okay. Thank you!

Raquel Rodriguez

Do we need to know how to label the graphs of different reactions for the final?

Raquel Rodriguez

How are you guys studying for the final? Are you guys going over the homework questions and midterm?

Raquel Rodriguez

When we are asked to find the concentration of different reactions and when they state do not use approximation, are we suppose to use the quadratic formula to find a non approximation answer?

Raquel Rodriguez

Are we going to have to know how to integrate the equations with derivatives in them?

Raquel Rodriguez

What are the units of the zero, first and second order?

Raquel Rodriguez

Are we going to be asked on the final exam on how to write a rate law for a table with different concentrations and rates like he went over in class?

Raquel Rodriguez

My question for this homework problem is how do they know which one is the anode or cathode?

Raquel Rodriguez

Do the final review sessions start week 10?

Raquel Rodriguez

The test isn't cumulative its everything from week 6 and 7 topics

Raquel Rodriguez

I try to do all the homework problems with the Constant and Equation worksheet.

Raquel Rodriguez

What topic are you guys going to study on more for this second test?

Raquel Rodriguez

Do we need to know how to draw the diagram for either Test 2 or the final?

Raquel Rodriguez

Do we need to know how to draw the diagram for either Test 2 or the final?

Raquel Rodriguez

What are the units for Gibbs?

Raquel Rodriguez

What equation is used for phases changes?

Raquel Rodriguez

What are some examples of closed and isolated systems?

Raquel Rodriguez

Will we need to know the Van't Hoff equation for Test number 2 this week?

Raquel Rodriguez

Is the variable q in the internal energy heat?

Raquel Rodriguez

Yea but for the last outline, we haven't learned some of the topics. So, I was wondering if we are going to be tested on it?

Raquel Rodriguez

it's on Monday from 7-10pm

Raquel Rodriguez

Do you always have to covert your temperature units the K all the time?

Raquel Rodriguez

Does anyone know until what question we should worry about in the outline for the midterm?

Raquel Rodriguez

Why isn't heat and work not a state property?

Raquel Rodriguez

No the exam I feel is more weak acids and bases.

Raquel Rodriguez

So if they give me a Ka value it is most likely an ice table problem?

Raquel Rodriguez

Is their a way you can figure out you need to use an ICE table for the problem?

Raquel Rodriguez

Last quarter I did mine in different order and I recieved the full points for it. So the answer is no.

Raquel Rodriguez

How do you know when to use partial pressure in an equilibrium equation?

Raquel Rodriguez

Are we going to need to remember the quadratic formula?

Raquel Rodriguez

When doing ICE Table are we able to ignore the x that is in the denominator? and when is it only possible?

Raquel Rodriguez

How do we calculate the concentration of an acid or base?

Raquel Rodriguez

How do you figure our the bond lengths of a structure?

Raquel Rodriguez

Have people memorized the different values that come with the different orbitals? or is their a different way?

Raquel Rodriguez

You just need 250 points to pass the class. But a 70% is still a C and on.

Raquel Rodriguez

What is an easy way to find the charge of the molecule within the compound without drawing the structure?

Raquel Rodriguez

Can we attend an earlier lecture or are they all in a different pace?

Raquel Rodriguez

The answer key has two different lewis structures. I got the second one but not the first one. Do we always have to draw both of them out?

Raquel Rodriguez

Does anyone have an idea of how they would ask us about sigma and pi bond on our test?

Raquel Rodriguez

What is an easy way to figure out the hybridization?

Raquel Rodriguez

Thank you for the links.

Raquel Rodriguez

What is one way it is easy to remember the different shape names for Lewis structure?

Raquel Rodriguez

In the syllubus is says that you need 50% to get a c- or higher. Does that mean you need 250/500 points to pass the class?

Raquel Rodriguez

Why is it important to know about the Shrodinger equation?

Raquel Rodriguez

Why is it important to know about the Shrodinger equation?

Raquel Rodriguez

How many different shapes are their?

Raquel Rodriguez

What is this easiest way to draw balanced lewis structure?

Raquel Rodriguez

What is the conversion for Hz?

Raquel Rodriguez

What is the easiest way to remember the different orbitals and ml?

Raquel Rodriguez

What is the charge that the structure need to have to be the most stable?

Raquel Rodriguez

What are some ways you guys ar studying for the midterm?

Raquel Rodriguez

When would you guys like to meet up?

Raquel Rodriguez

Does anyone want to do a study group for the upcoming weekend?

Raquel Rodriguez

Do you guys know how many questions the midterm will have?

Raquel Rodriguez

Will it be free response questions or multiple choice?

Raquel Rodriguez

I am lost trying to answer this question can someone help me out? Infrared spectroscopy is an important tool for studying vibrations of molecules. Just as an atom can absorb a photon of suitable energy to move an electron from one electronic state to another, a molecule can absorb a photon of electr...

Raquel Rodriguez

You have to use de Broglie equation: wavelength = h/p [p = momentum = mass(kg) * velocity (m/s)]. So convert 5.15oz into kg: 5.15 * 28.9 * 10^-3 = 0.148835kg. Then mutliply the weight that is in kg by velocity( which needs to be converted into m/s from mi/h [92mi/h * 1609.34/3600 -> .4470388889mi/s...

Raquel Rodriguez

I am confused with the answer the textbook is giving me for this question. Protons and neutrons have nearly the same mass. How different are their wavelengths? Calculate the wavelength of each particle when traveling at 2.75 105 m s 1 in a particle accelerator and report the difference as a percenta...

Raquel Rodriguez

You will have to wait until the end of the quarter. So you can not what grade you have until the end of the quarter because that is how it was for my summer classes.

Raquel Rodriguez

oh okay. I was just making sure because people told me we didn't need it.

Raquel Rodriguez

I was wondering if we need to use the Rydberg formula on the test that is coming up?

Raquel Rodriguez

Hi. I need help with this questions because I got a specific answer but the answer key says something else. Can someone tell me what I did wrong? F.9 Vanillin is found in vanilla extracted from Mexican orchids. A report on the analysis of vanillin listed the mass percentage composition as 63.15% C, ...

Raquel Rodriguez

Can we do more than 7 questions?

Raquel Rodriguez

Does anyone know if our first test will be multiple choice?

Raquel Rodriguez

Do you guys know when our first test is?
