Question

Identify the reactants and products from the word equation :
Phosphorous + Oxygen $\to$ Phosphorus pentaoxide
Aluminium + Nitrogen $\to$ Aluminium nitride
Copper carbonate $\to$ Copper oxide + Carbon dioxide
Sodium + Water $\to$ Sodium hydroxide + hydrogen
Mercuric oxide $\to$ Mercury + oxygen

Answer 1

The substances which are on the left side of the arrow are generally reactants and the substances which are on the right side of the arrow are generally product.

Reactant Product

$1/2P_4+\frac{5}{2}{O}_2⟶P_2{O}_5$

$Al+\frac{3}{2}{N}_2⟶Al{N}_3$

$CuC{O}_3⟶CuO+C{O}_2$

$Na+H_{2}O⟶NaOH+1/2H_2$

$HgO⟶Hg+1/2O_2$
