4. A chemist adds some zinc shavings to a beaker containing a blue solution of copper chloride. The contents of the beaker are stirred. After about an hour, the chemist observes that the blue colour has not completely disappeared. (a) Write a balanced chemical equation to describe this reaction. (b) What other observations would you expect the chemist to make? (c) According to the chemist's observations, which reactant was the limiting reactant? (d) The beaker contained 3.12 g of copper chloride dissolved in water. What does this tell you, quantitatively, about the amount of zinc that was added?
