How many moles of oxygen react with hydrogen to produce 22.8 mol of H2O? The balanced equation is as follows: 2H2 + O2 → 2H2O

How 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

2H₂ + O₂ → 2H₂O
[tex] \frac{22.8 mol H2O}{1} [/tex] * [tex] \frac{1mol O2}{2 mol H2O} [/tex] =
 11.4 mols O₂

CaCO₃ + 2HCl → CaCl₂ + CO₂ + H₂O
[tex] \frac{35.48molHCl}{1} * \frac{1 mol CO2}{2 mol HCl} * \frac{44.01 grams CO2}{1 mol CO2} [/tex] =
780.7 grams CO₂

hope this helped!
