Water can be obtained as the only product during the?
- combustion of hydrocarbons
- neutraliization of an acid by base
-
combustion of hydrogen
- electrolysis of brine
The correct answer is: C
Explanation
In flame of pure hydrogen burning in air, the hydrogen (H2) reacts with oxygen (O2) to form water \(H_2O\) with the release of energy.
Hydrocarbon combustion refers to the chemical reaction where a hydrocarbon reacts with oxygen to create carbon dioxide, water, and heat.
The electrolysis of brine yields chlorine, hydrogen and sodium hydroxide.
