Question

Identify the type reaction from the following.

$H_{2}C{O}_3\left(aq\right)\to H_{2}O\left(l\right)+C{O}_2\left(g\right)$

• A. Combustion reaction
• B. Decomposition reaction
• C. Displacement reaction
• D. Double displacement reaction

Answer 1

The correct option is B Decomposition reaction

$H_{2}C{O}_3\left(aq\right)\to H_{2}O\left(l\right)+C{O}_2\left(g\right)$

In this reaction, carbonic acid decomposes to form water and carbon dioxide gas. Hence, this is the example of a decomposition reaction.
