(a)

Interpretation Introduction

Interpretation:

The product has to be predicted, balanced and net ionic reaction for the gas-generating reaction, ${\text{Na}}_{\text{2}}{\text{CO}}_{\text{3}}{\text{(aq) and H}}_{\text{2}}{\text{SO}}_{\text{4}}\text{(aq)}$ has to be written.

Concept introduction:

Balancing reaction:

Balanced reaction is a chemical reaction in which number of atoms for each element in the reaction and the total charge are same on both reactant side and the product side.

Steps in balancing the information

• Step 1: Write the unbalanced equation
• Step 2: Find the coefficient to balance the equation.
• The coefficient should be reduced to the smallest whole number.

Gas forming reaction: The reaction of acid and metal carbonates which produce carbonic acid. The carbonic acid decomposes which gives water and carbon dioxide.

Most of the ionic compounds are soluble in water, very few of the ionic compounds are sparingly soluble, and some of the ionic compounds are insoluble in water. When it is soluble in water ions gets separated in the solution.

Interpretation Introduction

Interpretation:

The product has to be predicted, balanced and net ionic reaction for the gas-generating reaction, ${\text{K}}_{\text{2}}{\text{SO}}_{\text{3}}\text{(aq) and HCl(aq)}$ has to be written.
