Question

The properties of water are ___________ from that of oxygen and hydrogen.

Answer 1

• Chemical reaction - A process in which one or more substances react to form one or more new substances.
• The substance that combines or react is known as the reactant.
• The substances that are formed in a reaction are known as products.
• Example - When hydrogen reacts with oxygen it forms a water molecule that has completely different properties than reactants.

$\underset{\mathrm{Reactants}}{\underset{\mathrm{Hydrogen}}{2{\mathrm{H}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Oxygen}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}}\to \underset{\mathrm{Product}}{\underset{\mathrm{Water}}{2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}}$

Thus, the properties of water are completely different from that of oxygen and hydrogen.
