Questions: Identify the reaction type for the following reaction. 2 H2O(l) → 2 H2(g) + O2(g) single-displacement double-displacement decomposition synthesis

Solution Steps

The given chemical reaction is:

$$2 \mathrm{H}_{2} \mathrm{O}(\mathrm{l}) \rightarrow 2 \mathrm{H}_{2}(\mathrm{~g})+\mathrm{O}_{2}(\mathrm{~g})$$

This reaction involves the breakdown of water ($\mathrm{H}_{2}\mathrm{O}$) into hydrogen gas ($\mathrm{H}_{2}$) and oxygen gas ($\mathrm{O}_{2}$).

To identify the reaction type, we need to understand the nature of the transformation:

• Single-displacement reaction: Involves an element displacing another in a compound.
• Double-displacement reaction: Involves the exchange of ions between two compounds.
• Decomposition reaction: A single compound breaks down into two or more simpler substances.
• Synthesis reaction: Two or more simple substances combine to form a more complex compound.

In this case, a single compound ($\mathrm{H}_{2}\mathrm{O}$) is breaking down into two simpler substances ($\mathrm{H}_{2}$ and $\mathrm{O}_{2}$).
