Question

How many grams of water formed by reacting 2gm of H2 with 2gm of O2

Answer 1

@Abmon98 .... Bro any idea about this

Answer 2

H2+1/2O2--->H2O
2/2=1 moles
2/32=0.0625
use the limiting reagent which is oxygen, 0.0625*18=1.125 grams although iam not sure

Answer 3

but the options are...A) 2gms B) 2.25gms C)4gms D) 4.5gms

Answer 4

iam sorru i didnt multiply the number of moles of oxygen by 2 because the ration 1/2:1

Answer 5

The answer is B. It's true that oxygen is the limiting reagent, but you need to take the stoichiometric ratios into account when finding the mass produced.

1 H2O/ ½ O2 = x H2O / 0.0625 O2
x = 0.125

So you have 0.125 moles of H2O produced, which is 18 x 0.125 = 2.25 g.

Answer 6

@Abmon and @matt101......Thanks man...
