Question
State one characteristic the chemical reaction which takes place when:$2\text{H}_2\ +\ \text{O}_2\xrightarrow{\ \ \ \ \ \ \ \ \ \ \ }2\text{H}_2\text{O}$
✓

Answer

$2\text{H}_2\ +\ \text{O}_2\xrightarrow{\ \ \ \ \ \ \ \ \ \ \ }2\text{H}_2\text{O}$The reaction comes under decomposition reaction since the water molecule is breaking into individual gaseous molecules of hydrogen and oxygen. On the other hand, it can also be considered as electrolysis process if you apply electricity to the water. Actually, elctrolysis itself is a decomposition reaction because larger molecules will break down into its individual compounds.
