0.98 grams of Copper (II) chloride was dissolved in water, and a piece of aluminum wire with a mass of 0.56 g was placed in the solution. The blue color due to copper (II) chloride soon faded and a red precipitate of solid copper was observed. After the blue color had disappeared completely, the leftover aluminum wire was removed from the solution and weighed. The mass of the leftover aluminum wire was 0.43 g. 1. Calculate the number of moles of copper (II) chloride and aluminum metal that reacted.

2. Based on these calculations, what is the mole ratio of copper (II) chloride to aluminum metal? (round to the nearest whole number)

3. What happened to the aluminum metal in the reaction?

4. Write a balanced chemical equation for the single replacement reaction of copper (II) chloride with aluminum.
