it must have a charge.) Will a reaction occur when of the following substances are mixed? If yes, what product is driving the reaction (include the state)? If no reaction, write NR. Product formed Substances a. Cu (NO302 (aq) and NaoH (aq) b. Ca(s) and HCl (aq) c, HClo.(aq) and KoH(aq) d. K2So.(aq) and Sr(C2H3O2)2 The substance Hc Hao, in water is a:

Explanation / Answer

All nitrates are soluble in water.

A double decomposition reaction occurs only when one of the products is a precipitate or a gas.

a) Cu(NO3)2 (aq) +2 NaOH (aq) -------> Cu(OH)2 (s) + 2NaNO3(aq) , a double decomposition reaction

b) Ca(s) + 2HCl(aq) ----------------> CaCl2(aq) + H2(g) , a combination reaction

c) HClO4(aq) + KOH(aq) --------------------> KClO4 (aq) + H2O(aq) , an acid - base reaction

d) K2SO4(aq) + Sr(C2H3O2)2 (aq) --------------> 2K(C2H3O2) (aq) + SrSO4 (s)

A double decomposition reaction. SrSO4 is a sparingly soluble salt
