Question

match the reactants with the products. copper sulfate + oxygen copper + water copper oxide zinc sulfate + copper aluminum chloride + copper aluminum + copper chloride copper + oxygen copper oxide + hydrogen copper sulfate + zinc

Explanation:

Step1: Analyze metal - salt reaction

Aluminum is more reactive than copper. When aluminum reacts with copper chloride, a single - displacement reaction occurs, and the products are aluminum chloride and copper. So, aluminum + copper chloride → aluminum chloride + copper.

Step2: Analyze copper oxidation

Copper reacts with oxygen to form copper oxide. The chemical reaction is \(2Cu + O_{2}
ightarrow2CuO\). So, copper + oxygen → copper oxide.

Step3: Analyze reduction of copper oxide

Hydrogen can reduce copper oxide. The reaction is \(CuO + H_{2}
ightarrow Cu + H_{2}O\). So, copper oxide + hydrogen → copper + water.

Step4: Analyze metal - salt displacement

Zinc is more reactive than copper. When zinc reacts with copper sulfate, a single - displacement reaction occurs, and the products are zinc sulfate and copper. So, copper sulfate + zinc → zinc sulfate + copper.

Answer:

aluminum + copper chloride → aluminum chloride + copper
copper + oxygen → copper oxide
copper oxide + hydrogen → copper + water
copper sulfate + zinc → zinc sulfate + copper
