Question

Will the following reaction occur spontaneously? Ca + CuCl2 --> CaCl2 + CuExplain why.

Answer 1

The reaction will occur spontaneously

YES

Step-by-step explanation

Given information

`\text{ Ca +CuCl}_2\text{ }\rightarrow\text{ CaCl}_2\text{ + Cu}`

The above reaction is an example of a single replacement reaction.

The Ca displaces Cu on the left-hand side of the reaction to produce CaCl2.

According to the metal activity series chart, Calcium is more reactive than copper and it will displace copper during a chemical reaction.

Therefore, the reaction will occur spontaneously.
