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....
