Answer 1

Answer :

1. Aluminium + Oxygen ➝ Aluminium oxide

$\sf{Al+{O}_{2} \longrightarrow \: {Al}_{2}{O}_{3}}$

Balanced equation :

$\sf{4Al+{3O}_{2} \longrightarrow \: {2Al}_{2}{O}_{3}}$

2. Sodium hydroxide + Sulphuric acid ➝ Sodium sulphate + Water

$\sf{{NaOH}_{4}+{H}_{2}{SO}_{4} \longrightarrow \: {Na}_{2}{SO}_{4}+{H}_{2}O}$

Balanced equation :

$\sf{{2NaOH}_{4}+{H}_{2}{SO}_{4} \longrightarrow \: {Na}_{2}{SO}_{4}+{2H}_{2}O}$

3. Manganese dioxide + hydrochloric acid ➝ Manganese chloride + chlorine + water

$\sf{{MnO}_{2}+HCl \longrightarrow \: {MnCl}_{2}+{Cl}_{2}+{H}_{2}O}$

Balanced equation :

$\sf{{MnO}_{2}+4HCl \longrightarrow \: {MnCl}_{2}+{Cl}_{2}+{2H}_{2}O}$

4. Potassium chlorate ➝ Potassium chloride + Oxygen

$\sf{{KClO}_{3} \longrightarrow \: KCl+{O}_{2}}$

Balanced equation :

$\sf{{2KClO}_{3} \longrightarrow \: 2KCl+{3O}_{2}}$

5. Potassium permanganate + Hydrochloric acid ➝ Potassium chloride + Manganese chloride + Chlorine + Water

$\sf{{KMnO}_{4}+HCl \longrightarrow \: KCl+{MnCl}_{2}+{Cl}_{2}+{H}_{2}O}$

Balanced equation :

$\sf{{2KMnO}_{4}+16HCl \longrightarrow \: 2KCl+{2MnCl}_{2}+{5Cl}_{2}+{8H}_{2}O}$

More Information

The chemical equation in which number of atoms of each element are equal on both side ( reactants and products ) of the equation is called balanced equation.

The simplest chemical equation is hit and trial method.

The substances which take place in the reaction are called reactants. The substances which are produced as a result of chemical reaction are called products.
