Question

What Type of Reaction is the following: lithium carbonate → lithium oxide + carbon dioxide

1. Synthesis
2. Decomposition
3. Single Replacement
4. Double Replacement

Answer 1

Answer: 2. Decomposition

Explanation:

Synthesis reaction is a type of chemical reaction in which two reactants combine to give a single product.

Decomposition reaction is defined as the reaction where a single substance breaks down into two or more simpler substances.

lithium carbonate → lithium oxide + carbon dioxide

$LiCO_3\rightarrow LiO+CO_2$

Single replacement reaction is a type of chemical reaction in which more reactive element displaces the less reactive element from its salt solution.

A double replacement reaction is one in which exchange of ions take place.
