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
Explication
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.
