  1. 3. the actual yield of product from a chemical reaction divided by the theoretical yield, with the quotient multiplied by 100 to give a value in percent
  2. 5. for a chemical reaction, the maximum amount of product possible for a given amount of reactants
  3. 6. a reactant that is present in excess relative to the limiting reactant. When the reaction is ccomplete the limiting reactant will be completely used up, replaced by product and unused excess reactant
  4. 7. 6.0223x10^23
  5. 10. chemical formula in which the numeric subscripts indicate th ratio of elements in a substacne expressed as the lowest possible numbers. One molecule of the substance may contain the number of atoms shown or a multiple of those numbers
  6. 12. the mass of 1 mole of any substance, expressed in grams
  7. 13. the amount of any item that contains 6.0223x10^23 items

  1. 1. the branch of chemistry that deals with measuring the quantities of reactants and products involved in chemical reactions
  2. 2. the reaction of any substace with oxygen (O2)
  3. 4. in a chemical reaction,a reaction that, because there is less of it than needed to react with the total amount of the other reactants, determines how much product is produced. All of it is used in the reaction.
  4. 8. the SI base unit of amount of a substance
  5. 9. the number of units in one mole
  6. 11. the experimental amount of product obtained in a chemical reaction
