a. 2ag(s) + zn(no3)2(aq) → 2agno3(aq) + zn(s)

b. 2cu(no3)2(aq) + 2ag(s) → 2agno3(aq) + cu(s)

c. cuso4(aq) + fe(s) → feso4(aq) + cu(s)

d. 3mgso4(aq) + 2al(s) → al2(so4)3(aq) + 3mg(s)

they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.
