Stoichiometry of Chemical Equations

3. substance undergoing a chemical or physical change; shown on the left side of the arrow in a chemical equation
6. reaction redox reaction involving the oxidation of an elemental substance by an ionic species
7. relationships between the amounts of reactants and products of a chemical reaction
9. number placed in front of symbols or formulas in a chemical equation to indicate their relative amount
11. relatively high solubility; dissolving to a relatively large extent
15. reactant present in an amount lower than required by the reaction stoichiometry, thus limiting the amount of product generated
16. process in which an element’s oxidation number is decreased by gain of electrons
17. amount of product formed in a reaction
18. substance that produces OH− when dissolved in water
19. reaction between an acid and a base to produce salt and water
20. chemical equation with equal numbers of atoms for each element in the reactant and product

1. amount of product that may be produced from a given amount of reactant(s) according to the reaction stoichiometry
2. a chemical reaction where two ionic compounds exchange their positive ions (cations) to form two new compounds
4. process in which an element’s oxidation number is increased by loss of electrons
5. substance that produces H3O+ when dissolved in water
8. insoluble product that forms from reaction of soluble reactants
9. symbolic representation of a chemical reaction
10. vigorous redox reaction producing significant amounts of energy in the form of heat and, sometimes, light
12. measure of the efficiency of a reaction, expressed as a percentage of the theoretical yield
13. substance formed by a chemical or physical change; shown on the right side of the arrow in a chemical equation
14. chemical equation in which all reactants and products are represented as neutral substances
21. reactant present in an amount greater than required by the reaction stoichiometry
