Hydrogen and oxygen gas combine explosively to produce water. Write a balanced chemical equation for this process. If 10 moles of hydrogen reacted with oxygen, what volume of liquid water could be produced?

Answer 1

2H2 + O2 ==> 2H2O
10 mol H2 x (2 mols H2O/2 mols H2) = 10 mol x 2/2 = ? mols H2O

grams H2O = ? mols H2O x molar mass H2O = ?
Assuming the density of water is 1.0 g/mL, then mL H2O = grams H2O.
