the mole ratios among the reactants and products in a chemical reaction
chemical equation - CORRECT ANSWER -
a description of the identities and proportions of reactants and proucts
reactants - CORRECT ANSWER -substances consumed during a chemical reaction
products - CORRECT ANSWER -substances formed during a chemical reaction
molecular mass - CORRECT ANSWER -the mass in amu of one molecule of a molecular compound
molar mass - CORRECT ANSWER -the mass of one mole of a substance
formula mass - CORRECT ANSWER -mass in amu of one formula unit of a compound
law of conservation of mass -ECORRECT ANSWER -
the principle that the sum of the massesEof the reactants in a chemical reaction is equal to the su
