Answer 2

Required solution :-

a. Word equation: Dilute sulphuric acid + Zinc → Zinc sulphate + Hydrogen gas

Balanced equation: H₂SO₄(aq) + Zn → ZnSO₄(aq) + H₂(g)

b. Word equation: Dilute hydrochloric + Magnesium → Magnesium chloride + Hydrogen gas

Balanced equation: 2HCl(aq) + Mg → MgCl₂(aq) + H₂(g)

c. Word equation: Dilute sulphuric acid + Aluminium → Aluminium sulphate + Hydrogen gas

Balanced equation: 3H₂SO₄(aq) + 2Al(s) → Al₂(SO₄)₃(aq) + 3H₂(g)

d. Word equation: Dilute hydrochloric acid + Iron → Ferrous chloride + Hydrogen gas

Balanced equation: 6HCl(aq) + 3Fe(s) → 3FeCl₂(aq) + 3H₂(g)

More information :-

A balanced chemical equations have the same number and type of each atom on both left and right sides of the equation.

The coefficients in a balanced equation must be the simplest whole number ratio.

Word equation represents a chemical reaction with the names of the substances involved.

A word equation never contains any chemical symbols or formulae.

To balance an equation, multiply the iron on the LHS by 3. Then the number of atoms of each element becomes equal on the left and the right side as well. Thus, this equation becomes a balanced equation.
