Question

identify the type of reaction for the following equation: 2nahco₃ → na₂co₃ + h₂o + co₂. synthesis. decomposition. single replacement. double replacement.

Explanation:

A decomposition reaction is when a single compound breaks down into two or more simpler substances. The equation \(2\text{NaHCO}_3
ightarrow \text{Na}_2\text{CO}_3 + \text{H}_2\text{O} + \text{CO}_2\) shows one reactant (\(\text{NaHCO}_3\)) breaking into three products, which fits decomposition. Synthesis is combining substances, single replacement involves one element replacing another in a compound, and double replacement involves two compounds exchanging ions—none of these match here.

Answer:

B. Decomposition
