Reactions

Metal + nonmetal =

• binary salt

• synthesis

metal oxide + H2O =

• metal hydroxide

• products = metal(OH)\n

• balance

• solubility rules: 1A, Ca and down

• ionize if soluble

nonmetal + H2O =

• polyatomic acid

• smush method

• reduce to polyatomic ion with balanced coeffienct

• write netI

exceptions to smush method

phosphorous, arsenic, antimony (straight to polyatomic acid)

metal oxide + nonmetal oxide =

• polyatomic salt

• metal oxide = base, “metal(OH)\n”

• nonmetal oxide = acid, add H2O, smush, polyatomic acid

• combine metal with polyatomic acid -H

• balance

metal sulfide + acid =

• metallic salt + hydrogen sulfide

• MQ: double displacement; should have H\2S

• write solubility + balance

• ionize: if (aq) and strong acid, NOT WEAK ACIDS
