2H2 + O2 ---> 2H2O
1 mole of H2 = 2g 1 mole of O2 = 32g 1 mole of H2O = 18g
according to the reaction: 2*2g H2---------------32g O2 1,6g H2----------------- x g O2 x = 12,8g O2
so reaction is stechiometric
32g O2---------------- 2*18g H2O 12,8g O2 -------------- x x = 14,4g H2O
answer: 14,4g of water vapour

When a hydrogen-filled balloon was ignited and 1.60g of hydrogen reacted with 12.8g of oxygen, the amount of water vapor formed can be calculated using the balanced chemical equation:
2 H₂(g) + O₂(g) → 2 H₂O(g)
According to stoichiometry:
2 moles of H₂ (which is 2 x 2.02g = 4.04g) react with 1 mole of O₂ (32.0g) to produce 2 moles of H₂O (2 x 18.02g = 36.04g of water).
Since the reaction is completely balanced and water vapor is the only product, the total mass of water vapor formed will be the sum of the masses of hydrogen and oxygen that reacted, which is 1.60g + 12.8g = 14.4 grams of H₂O vapor.

The reaction between hydrogen and oxygen produces 14.4 g of water vapor when 1.60 g of hydrogen reacts with 12.8 g of oxygen. Moles of each reactant were calculated, confirming they are in stoichiometric proportions. The conversion to grams shows that 14.4 g of H₂O is formed.
