Question

Liquid water can be separated into hydrogen gas and oxygen gas through electrolysis. 1 mole of hydrogen gas and 0.5 moles of oxygen gas is produced from 1 mole of liquid water collected in separate 10 L containers at 1 atm. Will the temperatures of the gases be equal? In one to two sentences, use the ideal gas law to explain your answer.

Answer 1

P V= n R T
V is the same for both
R is the same for both
P is the same for both
so
P V / R = n T = same for both
if n goes up, T goes down
thus
if n is 1 for H2 and .5 for O2
The H2 is hotter

Answer 2

Ummm..... am I the only one confused by that answer?

Answer 3

Me too are you taking the Gas Unit test? I’m having trouble with the test.

Answer 4

I am on the gases unit test and I am stuck. I don't know any of the answers

Answer 5

hold up do you do connections academy?

Answer 6

i do

Answer 7

Same I’m in connections too

Answer 8

so we all cheat? hahhaha

Answer 9

The ideal gas law is PV=nRT. If you 1x10(the 1atm times the 10L), divide that by the 0.5x0.0820574 (the 0.5 being the mole and the 0.0820574 being where R is the ideal gas) you get 243.75. So yes, the temperatures of the gases will be equal.

Answer 10

It is an Honor Code violation to use internet resources, such as this website, on your test essay questions. Doing so will result in a zero on the essay question and a discipline report. --Mrs. Seger

Answer 11

NO BODY CARES ANYMORE

Answer 12

im literally seeing this teacher's name everywhere

Answer 13

I have seen her name on the last four things I have looked at.

Answer 14

Perhaps you should not be using resources on your tests. I teach this course, so I am well aware of what is going on.

Answer 15

Yo Mrs.Seger is the answer here right tho? LOL

14-17 your on your own

Answer 17

Haha, most responses here are actually very wrong. Some are on the right track but don't end up in the right place. Others are completely incorrect.

Answer 18

So has anyone got an "Honor Code violation" on the test yet even if they put it in their own words? Just wording?

Answer 19

mrs seger is most def 100% a karen

Answer 20

She's just trying to warn us! It's her job as a teacher to encourage us not to cheat! Come on guys don't be mean. She has seen some of you guys are at connections she could report this to the school! How about instead of being mean and rude ask her for help. She teaches this subject just ask her for help!

Answer 21

make me!
Your just mad because im correct and I'm calling you out!

Answer 22

I think Be Kind is correct tho it may be annoying to be reminded about the guidelines, but would you rather have a teacher that didn't care. At least this teacher does I'd rather be reminded about it than just get an F on the assignment. Plus I'm sure if you ask her for help she'll help you. Whos gonna know more about the subject a bunch of students learning it for the first time or a teacher who teaches this for a living

Answer 23

Mrs. Nowwhere numbers 2, 5, & 7 answers are wrong
(correct answers below
2. volume and temperature Directly proportional
pressure and volume inversely proportional
pressure and temperature directly proportional
5. It is a straight line with a positive slope showing that an increase in temperature results in an increase in volume.
7. When the temperature is held constant and volume increases the pressure increases.

also, stop being rude to each other especially if your want us to help you. WHo cares if she tells us we are violating its her job 🙄you don't have to be rude just ignore her~gosh for some high schoolers your all very immature

Answer 24

I like seeing her getting dragged because she's at fault for notifying our parents about these websites but chill a little.. We can use *other* resources. I'm sure we're also here because brainly gave a 404

Answer 25

i mean... do we really need to be warned about using "other" resources? like we all are aware of the honor code and we are willingly using online sources anyways sooo
and if you get caught using it, its your fault yk

Answer 26

Answer 28

ima be 100% I didn't cheat and I still got told I was cheating so now i just cheat

Answer 29

Potato, I hope your are correct!!!!

Answer 30

Potato I'm not apart of connexus, I am doing zoom at one of my schools and trying to complete the test. I know I should studied, well.... which I did 5x, but please tell me, is this correct?????!!!!

Answer 31

this website is so entertaining lmaoo

Answer 32

just to let yall know, if you find the answers i recommend understanding it and putting it in different words. Some teachers don't but a lot do check your answers to see if they're copied especially art, english, and history teachers. don't take chances becaue you can get kicked out of connexus

Answer 33

anyways the answer: container A has 1 mole of H2, container B has 0.5 moles of O2

PV=nRT Each container has the SAME P and V , so container A must have a lower T since PV=1XRXT, while container B has 0.5XRXT and so T is greater in order to keep PV constant

Answer 34

Dabi i appreciate u trying to help but that makes 0 sense

Answer 35

Okay i see u copied someone elses answer from "another source" so it hopefully means its correct for u since it was posted 2 weeks ago and ur re posting it

Answer 36

I genuinely don't understand why other students shame the ones who cheat tbh. As if they wouldn't do the same in their position. Or as if they understand the circumstances that push us to so any and everything to complete our assignments. its as if the get a sick satisfaction from publicly shaming the ones who are struggling the most, as if it gives you a sense of superiority. Or in other words just let us do what we have to do.

Answer 37

Some of us have to risk it cus chemistry makes 0 sense. School teaches us useless information. I'm not going into a career that has anything to do with chemistry. Class is like a jail cell. There is no creativity at all. School just forces us into a horrible lifestyle and sets high standards. You don't need to go to college to be successful in life and none of this useless information is going to help us. Like bro why make us take a math course that actually isn't going to help us in life?! Why can't schools teach us something that's actually important like how to pay taxes!? Instead they put us through heck and force us to compete for grades because if you don't get an A or a B then your automatically not smart and suck. And to Mrs. Seger imagine actually laughing at a kid for getting the answers wrong, sounds pretty petty tbh. I get it teachers hate for us to cheat but like maybe we wouldn't have to if we weren't so pressured into getting good grades.

Answer 38

Your right, Demon Slayer!!! Oh and people pay taxes via phone, computer, or visiting a federal building.

Answer 43

well this has been a fun thread to read in the end we’re all cheaters so it doesn’t really matter it’s not like we will ever need to know any of this ever so you teachers can muck my barn

Answer 44

Demon slayer is 100% correct. If you think about it, school work is very repetitive. I learned about solids, liquids, and gas in second grade. Here I am doing it again, but it was just added onto with more work and information piled into our brains. To me, it just slowly gets more confusing which makes it very boring to learn and hard to keep up with. Same with math, I learned division, fractions, multiplication, etc way back in grade school. Here I am in 10th still working with multiplication, division, fractions, etc but they’ve just got more work with it. I understand we are not supposed to cheat. I understand it won’t help in the future. But for once, can we learn work that’ll benefit our future greater than this will?

Answer 45

Also, I believe school isn’t really about learning anymore. I’m failing with a 60% and have to have it up to a 85% within 4 days. Throughout this whole course, my grades have been dragging as well as the time frames I complete my work in. My teacher is emailing my mom left and right about “she needs to have her grade up.” “If her grade is not above an 85% she will not receive all of her credits.” But not once has my teacher asked if I’m understanding my work. My teacher has not asked if I’m falling behind because it’s difficult/confusing. He just wants me to have my grade up.
