Answer

Answer:

A. $\mathrm{Li_2CO_3}\rightarrow\mathrm{Li_2O}+\mathrm{CO_2}$

Brief Explanations:

A decomposition reaction breaks a single compound into two or more simpler substances. In $\mathrm{Li_2CO_3}\rightarrow\mathrm{Li_2O}+\mathrm{CO_2}$, lithium carbonate breaks down into lithium oxide and carbon - dioxide. The second option is a single - displacement reaction, the third is a combination reaction, and the fourth is a combustion reaction.
