A balanced chemical equation gives…
The relative amounts of reactants used and products formed in a particular reaction
The mass of one mole of a particular atom or molecule
The molar mass
In many cases the amounts of reactants in a reaction are such that one reactant runs out before the other. At this point the reaction will stop. The reaction that runs out is called the…
