Question

Stoichiometry: Limiting reagent

Answer 1

Is this enough information for you to help me out?

Answer 2

I'm not sure. But for me, I don't think there's enough info.
They are just balanced equation.
Do they tell you like how many grams of each element is used in the reaction?

Answer 3

Sure, 'll give you all of those information. Wait a minute.

Answer 4

All of them are in the same order like the one above.

Answer 5

oh. this isnt that bad. they even solved it for you.

look at the last column (left over)
the limiting reagent is the one with fewer number of leftovers

Answer 6

and i think the last one is special. since both are used up, there is no limiting reagents

Answer 7

Lol, I solved it but kinda confused on the question I posted.

So the last one has no limiting reagents? N/A.

Answer 8

oh. i thouhgt those were given.

and yea, last one should be N/A

Answer 9

limiting reagent is that one that is used up in the reaction before the other reactant

Answer 10

Thanks, do you know the other two?

Answer 11

yea. look at the one with ) leftover. that would be your limiting reagent

Answer 12

^0 leftover

Answer 13

Hmm, is it okay if you could show me how to correctly get that? Sorry, just need to understand.

Answer 14

ok. lets lok at the second one

for the leftover column, you have

9N2 and 0H2
this shows you have 9 moles of N2 left
and 0 moles of H2 left.

because there are 0 moles of H2 left after the reaction, that means that it is the limiting reagent

Answer 15

the H2 limited your reaction. it was all used up in the reaction.

That also means you have an excess of N2, which you dont have to worry about in your problem.

Answer 16

Oh alright, so overall, the second column would be 0 for the answer, that it?

Answer 17

what do you mean second column would be 0?

Answer 18

We're solving the second column right?

Answer 19

oh. i thought we were answering your question.

Answer 20

If H2 is the limited reaction, how come 9N2 wouldn't be the the amount of the reaction?

Answer 21

I feel so dumb for asking all of these questions.

Answer 22

so you have your balance equation and your reactants
