Question

How many grams of H2 are needed produced in 11.13 grams of of NH3

Answer 1

can you write an equation for the reaction and balance it?

Answer 2

3H2+N2\[3H _{2}+N _{2}\rightarrow2NH _{3}\]

Answer 3

ignore the first part

Answer 4

okay good stuff, now covert the grams of NH3 to moles

Answer 5

ok so find the molar mass?

Answer 6

well yeah, then find the moles


moles=mass/molar mass

Answer 7

17.034

Answer 8

.653

Answer 9

okay so you have this
3H2+N2→2NH3
x 0.653

now, you have to use the coefficients to form a ratio between the 2 substances, since they're not in a one to one relationship.

aA + bB -> cC

moles of C/c = moles of A/a

Answer 10

see i dont understand that

Answer 11

all you have to do is normalize each one by diving the amount of moles by it's respective coefficient

\[\frac{ moles of H _{2} }{ 3 }=\frac{ moles of NH _{3} }{ 2 }\]

Answer 12

then solve for whatever you're looking for
