Question

Answer 1

#205 a question about the ideal gas law

Answer 2

ok just posted it

Answer 3

@Rushwr @Cuanchi

Answer 4

my first thought was: (if the pressure is lower) then the molecules must be hitting the walls of the container less

Answer 5

most likely the is issues created due to the strong intermolecular hydrogen bonding occouring between the gaseous water vapor

Answer 6

rip english

Answer 7

Yeah.. if there's some intermolecular bonding occurring then definitely I think that this would cause the molecules to hit the container less frequently then expected and lower the pressure

Answer 8

if the gaseous molecules are being held closer together they will not exert as high of a pressure

Answer 9

I agree, when i think of pressure i always think of a sealed container

Answer 10

ill post another one on gases right now

Answer 11

Got this wrong first time doing it

Answer 12

can't it be due to the presence of liquid water?

Answer 13

for the 2nd question it is B right?

Answer 14

I thought it was B as well

Answer 15

@taramgrant0543664 @sweetburger thoughts?

Answer 16

Sorry I went to make a sandwich lol but the second one is B the first one I was also questioning D a little

Answer 17

I will be back in 30 minutes. will get answers in the mean time !

Answer 18

Hmm i think that reads that "the base equation for explanation of defusion of gases"? if so I think the answer should be B. not really sure though...

Answer 19

For diffusion I normally use Graham's Law.
I know that A is for non-ideal gas
B is Boyles Law
C is ideal gas law
D is kinetic energy
looking at each of them the one that seems most like Graham's Law is Boyle's but I am making a lot of random assumptions to say that they would be similar enough

Answer 20

A is van der waals right?

Answer 21

Yep it is

Answer 22

Idk this link might be helpful Im still trying to come up with a clear answer https://www.chem.tamu.edu/class/majors/tutorialnotefiles/graham.htm

Answer 23

Maybe it is D then

Answer 24

no clue thb. at least well find out when @Photon336 brings back the answer

Answer 25

yeah now even I think that it is D

Answer 26

Ya for sure but D is making more sense then the other answers now after looking at that link we will find out eventually and hopefully it's not A or C cause that I think would screw us all up lol

Answer 27

Wait in which grade are u 2 now? Cuz I actually didn't know that there was a law called graham's law

Answer 28

I'm about to go into my third year of university studying chemistry

Answer 29

So u learned it there?

Answer 30

I knew it before but I really touched on it in my second year physical chemistry class since it is a huge portion of it

Answer 31

aaah maybe I will learn it at school after sometime. Chemistry is interesting right?

Answer 32

physical chemistry seems very scary

Answer 33

Chemistry there is a world of possibilities this coming year take classes from the simple stuff like organic, inorganic and biochem to physical chemistry and that talks about quantum mechanics and then in second semester I will be taking a class called computational quantum chemistry and that's where the fun stuff happens as in I make drugs on computers lol

Answer 34

But at school we haven't gone that deep ! But manageable

Answer 35

physical chemistry is about thermodynamics both classical and statistical and then it moves onto quantum mechanics its not too bad but it is not easy

Answer 36

what level of math did you need to complete?

Answer 37

In high school I did advanced functions as well as Calculus/ AP calculus and in university in first year I had to take calculus which is like the AP stuff but a little harder at times and then in second year I had to take differential equations which we studied odes or ordinary differential equations and i'm taking stats this next year for an easy credit

Answer 38

hopefully my ap calc goes well for me this year maybe i will have a shot at a chem major then.

Answer 39

I am really bad in maths.

Answer 40

@taramgrant0543664 do you plan on doing a PhD or are you looking to go to med school or something like that?

Answer 41

Chemistry is a great program you really need the math once you get farther into physical chemistry highly recommend paying really good attention to the integral stuff cause if you can only slide by on the basics it gets harder but for the most part if you can derive a formula and put formulas together and plug numbers in its not too bad

Answer 42

good that I am not planing on doing chem

Answer 43

I'm really not sure to tell you the truth, all I really want to do is be in a lab, the labs at university are so much better than the labs in high school (for the most part) and I absolutely loved the days when all I had where labs and spending 9 hours in the lab was a blast. I'm thinking I will do a masters but I don't know about phd

Answer 44

That sounds like it would be very cool/interesting. I like chemistry quite a bit. It's going to be hard to decide on what to major in a year from now. I'll probably chicken out and do biology tbh...

Answer 45

Biology is quite fun too I'm doing that as my minor

Answer 46

@Rushwr what grade are you in?

Answer 47

@taramgrant0543664 thanks for interesting information. Very helpful :).

Answer 48

Yeah I'm still schooling my last 2 years

Answer 49

No problem feel free to message me if you have any questions about them or bio, they are both fun the labs in both were fun in my opinion I even played around with E. coli in one of my labs they are both good majors that open a lot of doors you can do so much with either of them

Answer 50

Alright thanks a bunch :).

Answer 51

Thanks alot! @taramgrant0543664

Answer 52

You've still got time to learn that stuff you're already really smart @Rushwr and no problem @sweetburger you'll do great in which ever one you pick you're pretty smart too!

Answer 53

Thanks alot @taramgrant0543664 U are the only one who says it though. Cuz all my teachers are like u should work more. They always scold me saying that I'm not in the class and blah blah. Thank you again

Answer 54

Yeah you all are very smart

Answer 55

By the way I looked at the answer and it'S A

Answer 56

Yes agreed

Answer 57

@Rushwr you answered that question about decay, I didn't even know where to start (partly because its been three years since I have talked about that stuff) and you answered it like a pro you're doing good keep it up!!

Answer 58

A for the second question??

Answer 59

The second one was D.

Answer 60

\[KE = \frac{ 1 }{ 2 }Mv ^{2}\]

Answer 61

wait is this the low pressure high temperature ?

Answer 62

I closed that out and posted the answers for those as well in the other question

Answer 63

I was going to say that if the second one was A then I need get back to the books!

Answer 64

one thing i noticed was that all three were like different versions of the ideal gas law

Answer 65

Ya I noticed that too! I'm in the process of making a tutorial on gas laws so they all immediately jumped out and I thought it was a little odd.

Answer 66

Based on what you guys wrote, you could technically derive grahams law of diffusion from the kinetic energy of the particles
