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.
[tex]A+BC\rightarrow AC+B[/tex]
The chemical equation for the reaction of chromium metal and cobalt(II) chloride solution follows:
[tex]2Cr(s)+3CoCl_2(aq.)\rightarrow 2CrCl_3+3Co[/tex]
As, chromium lies above in the series. So, it can easily replace cobalt from its chemical reaction.
Hence, the chemical equation is written above.
