Increase the turns of the wire.

How many moles of oxygen react with hydrogen to produce 22.8 mol of H2O? The balanced equation is as follows: 2H2 + O2 → 2H2OHow many grams of CO2 are produced if 35.48 mol of HCl are reacted according to this balanced chemical equation? CaCO3 + 2HCl → CaCl2 + CO2 + H2O

Answers

2H₂ + O₂ → 2H₂O
(22.8 mol H2O)/(1) * (1mol O2)/(2 mol H2O) =
 11.4 mols O₂

CaCO₃ + 2HCl → CaCl₂ + CO₂ + H₂O
(35.48molHCl)/(1) * (1 mol CO2)/(2 mol HCl) * (44.01 grams CO2)/(1 mol CO2) =
780.7 grams CO₂
