Industrially, hydrogen chloride gas is made by the combination of hydrogen and chlorine: H2 + Cl2 ---> 2HCl reaction is complete. if a mixture of 362 mL of hdrogen and 345 mL of chlorine is caused to reat, a.) how many milliliters of H2 will be present after reaction has taken place? b.) how many milliliters of Cl2? c.) how many milliliters of HCl? (All columes are measured under the same conditions of temperature and pressure)
