Unit # 8 - CHEMICAL REACTIONS
Predict and Balance Chemical Reactions

Using the appropriate tools to predict whether the following reactions occur. If a reaction occurs, balance the chemical equation.

(a) Calcium metal was placed in hydrochloric acid.
(b) A solution of copper (II) sulfate, CuSO4, was poured into a galvanized (zinc-coated) bucket.
(c) Copper metal was dipped in a solution of sodium chloride, NaCl.
(d) Silver nitrate, AgNO3, and potassium chloride, KCl, are mixed.
(e) Potassium chloride, KCl, is mixed with iodine, I2.
(f) Aluminum sulfate, Al2(SO4)3, and barium nitrate, Ba(NO3)2, solutions are mixed.
(g) Sulfuric acid, H2SO4, and potassium hydroxide, KOH, solutions are mixed.
(h) A potassium bromide, KBr, solution is mixed with chlorine, Cl2, gas.
