Express your answer as a chemical equation. Identify all of the phases in your answer. Enter noreaction if no reaction occurs.

Answered by maham237 @


Answer: The chemical equation is written below.

Explanation:

Single displacement reaction is defined as the reaction in which more reactive element displaces a less reactive element from its chemical reaction.

The reactivity of metal is determined by a series known as reactivity series. The metals lying above in the series are more reactive than the metals which lie below in the series.

A+BC\rightarrow AC+B

The chemical equation for the reaction of chromium metal and cobalt(II) chloride solution follows:

2Cr(s)+3CoCl_2(aq.)\rightarrow 2CrCl_3+3Co

As, chromium lies above in the series. So, it can easily replace cobalt from its chemical reaction.

Hence, the chemical equation is written above.
