Question

Question 42 of 60 Submit If 2.00 moles of H2 and 1.55 moles of O2 react how many moles of H2O can be produced in the reaction below? 2 H2(g) + O2(g) → 2 H2O(9)

Answer 1

Given reaction

2H2(g) + O2(g) + 2H2O(9)

From the reaction , we can write

2.00 mol of H2 react =1.00 mol of O2

But amount of O2 used is 1.55 mol, so O2 used in excess.

Therefore, H2  is limiting reactant.

Again from the reaction, we can write

2.00 moles of H2 produce 2.00 mol of H2O

Amount of H2O produced = 2.00 mol
