Consider the reaction of hydrogen gas with chlorine gas:H2 + Cl2 2HCl4 molecules of hydrogen gas react with 6 molecules of chlorine gas.4 molecules of hydrogen gas in this reaction will produce 8 molecules of HCl.6 molecules of chlorine gas in this reaction will produce 12 molecules of HCl.Hydrogen is the limiting reactant.All BUT ONE statement about limiting reactants and reactants in excess is true. That isA)when the limiting reactant runs out, the reaction stops.B)the limiting reactant produces the least amount of product.C)the reactant in excess produces the greatest amount of product.D)when the reaction stops due to the limiting reactant, there will be some of the excess reactant left over.
