Question

PLEASE HELP.
(Stoichiometry Problem)

Answer 1

you mean i the products H2O?

Answer 2

no. The Product HOH.

Answer 3

is the same because they are talking of water(H2O) lol

Answer 4

Therefore, I know that step 1 is to balance the equation. Therefore

Answer 5

H2O is not the same as HOH, because the coefficients are different.

Answer 6

looks great, but look, you post on how many are needed to produce 11.2 of water ( again H2O)

Answer 7

:)

Answer 8

well, so the next step would be . .

Answer 9

No idea.

Answer 10

could you just please solve it, so i can try to deduce it. I really need to understand this for the exam.

Answer 11

\[\frac{ grams }{ mol }\]fin out in the elements of the reactants

Answer 12

you're going to need the periodic table i guess to find the grams of H and O

Answer 13

for 2 HOH it would be 11.2/20?

Answer 14

\[2H _{2} + O _{2} -> 2H _{2}O\] once you have balanced the equation you are able to answer the a) part
because the proportion in mols of the reactants has been found:

THERE are
Reactants Products

2 moles of H2 2 moles of H2O
1 mol of O2

the coeficient represent the number of moles per compound

Answer 15

in 1 mol of H2O there is 18 grams of H2O

Answer 16

in 2 moles would be 36 grams of H2O

Answer 17

That makes sense to you ?

Answer 18

yes

Answer 19

what's the next step?

Answer 20

please help,I understand what you've said I'm just not sure how it connects to a and b

Answer 21

I mean b

Answer 22

did you already finished a) ?

Answer 23

yah, it's just the balancing.

Answer 24

yeah but now ou have to find out how many noles there are in 11.2 grams of H2O

Answer 25

which is what i have no idea how to do

Answer 26

@iPwnBunnies she has a test. could you explain it to her step by step

Answer 27

So, you guys did Part A?

Answer 28

yes

Answer 29

no completly

Answer 30

oops, no. we have not

Answer 31

Omg, Rock seemed to have explained it well.

Answer 32

you see I have no idea how to find Part A, I know how to find the molecules though.

Answer 33

Ok, first find the amount of moles of H2O made from 11.2 grams.

Answer 34

\[(11.2 grams)\frac{1 mol}{18 grams} = ? mol\]

Answer 35

When you find that, we'll have to use mole ratios to figure out how many moles of each reactant is needed to make ? moles of water.
\[H: (? moles H2O)\frac{2 moles H2}{2 moles H2O} = ? moles H2\]

Answer 36

I know that in one mol of H20 we have eighteen grams. However, we have to moles we have 36

Answer 37

\[O2: (? mol H2O)\frac{1 mole O2}{2 mole H2O}\]

Answer 38

Yeah, but that's not needed here. We want to convert grams to moles.

Answer 39

Sorry, I wrote all that out b/c I have to go. Good luck.

Answer 40

i guess ill just fail the semester,i seriously dont understand these explanations

Answer 41

dont' say that

Answer 42

I was chemistryphobic

Answer 43

now I realized chemistry is fun and is not so hard

Answer 44

you know it's ironic though because my teacher gave us a few stoichiometry problems, and I actually solved all of them, and I'm pretty positive they're right.I'll post a question tomorrow and tag you and attach my work so you can double check. But, it's ironic tho because before I left class I specifically asked my teacher to explain this question to me, but she sucks at explaining, so..

Answer 45

;) you'll do it right, cheer yourself up: I know you're smart

Answer 46

certainly the work of a teacher is to know how to explain otherwise. . .

Answer 47

but i understand it happened to me and still

Answer 48

like I should be good at it, I'm in pre-cal.It's just you mix math and science together and it's just like no.

Answer 49

but this math is too believe me is just arithmetic

Answer 50

Anyway, it's super late so I have to go,but honestly it would mean the world to me if you could just solve this entire problem for me that way I could see it tomorrow morning, and at least have the worksheet correct which is another grade, and see if I could understand it, and if I have any questions on your work I promise I'll ask cause I really do need to know how to do it, otherwise I wouldnt have spent so much time here,I just dont want you to think Im one of those people just coming for answers. so please solve the entire thing for me on here

Answer 51

SOLVE IT as far you can and I'll help you out, don't be afraid in make mistakes

Answer 52

is the only way to learn ;)

Answer 53

so sleep tight, and I'll see you tomorrow

Answer 54

well i kinda have to go now. and actually idk my brain is weird because i learn better when i see an example with a full solution, because i can deduce it rather quickly and then apply it to a similar question. when i try to learn from doing i get confused

Answer 55

yeah i know how it feels but is good too try for ourselves annd then compare

Answer 56

alright, well please be on tomorrow. Ill show you the rest of my problems, and my solutions so you can verify them. (its only 3 more) and ill see if i can do this one which is highly unlikely

Answer 57

or maybe you need to watch some videos of stoichiometry and then aproach to the problem sometimes work for me

Answer 58

think positive and you will see i know sometimes can be tough

Answer 59

but once you get it is a piece of cake
