Question

drag the tiles to the correct boxes to complete the pairs. not all tiles will be used. 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: Recall single - displacement reaction

In a single - displacement reaction, a more reactive metal can displace a less reactive metal from its salt solution. For the reaction of aluminum and copper chloride ($2Al + 3CuCl_{2}
ightarrow2AlCl_{3}+3Cu$), aluminum is more reactive than copper, so the products are aluminum chloride + copper.

Step2: Recall oxidation reaction

When copper reacts with oxygen ($2Cu + O_{2}
ightarrow2CuO$), it undergoes an oxidation reaction and the product is copper oxide.

Step3: Recall reduction reaction

When copper oxide reacts with hydrogen ($CuO + H_{2}
ightarrow Cu + H_{2}O$), hydrogen acts as a reducing agent and the products are copper + water.

Step4: Recall single - displacement reaction

When copper sulfate reacts with zinc ($CuSO_{4}+Zn
ightarrow ZnSO_{4}+Cu$), zinc is more reactive than copper, so the products are zinc sulfate + copper.

Answer:

aluminum + copper chloride $
ightarrow$ aluminum chloride + copper
copper + oxygen $
ightarrow$ copper oxide
copper oxide + hydrogen $
ightarrow$ copper + water
copper sulfate + zinc $
ightarrow$ zinc sulfate + copper
