If a stoichiometry problem provides starting amounts of all reactants, you must _________________________________________________________________________________. (More than one answer may be correct)
Ignore all but one of the values given.
Determine the limiting reactant.
The theoretical yield is dependent on the limiting reactant. If amounts of all reactants are given, the problem cannot be solved.
Assume that the reactant with the smallest mass is the limiting reactant.

answer please number 1) a and b and 2 and 3
Experiment 4: Limiting reagent Often reactants are added in amounts different from the proportions given by the chemical equation in such cases, only one of the reactants may be completely consumed at the end of the reaction, whereas some amounts of other reactants will remain unreacted. The limiting reactant (or limiting reagent) is the reactant that is entirely consumed or converted to product when a reaction goes to completion....
