What type of reaction is this? 2H_(2)O_(2)arrow 2H_(2)O+O_(2) synthesis decomposition single replacement double replacement combustion

The given chemical reaction is:<br />\[ 2H_{2}O_{2} \rightarrow 2H_{2}O + O_{2} \]<br />In this reaction, hydrogen peroxide (\(H_{2}O_{2}\)) breaks down into water (\(H_{2}O\)) and oxygen gas (\(O_{2}\)). This is a classic example of a decomposition reaction, where a single compound breaks down into two or more simpler substances. The other options provided are not applicable to this reaction:<br />- Synthesis: This is a type of reaction where two or more simple substances combine to form a more complex compound.<br />- Single replacement: In this type of reaction, one element replaces another element in a compound.<br />- Double replacement: This involves the exchange of ions between two compounds.<br />- Combustion: This is a reaction that involves the burning of a substance in the presence of oxygen, usually producing heat and light.<br />Therefore, the correct answer is "decomposition".
