Explanation:
Reactants -
Nitric Acid [tex](HNO_3)[/tex]
Sodium Sulfate [tex](Na_2SO_4)[/tex]
Products -
Sulfuric Acid [tex](H_2SO_4)[/tex]
Sodium Nitrate [tex](NaNO_3)[/tex]
The reaction is as follows -
Nitric Acid + Sodium Sulfate ⇒ Sodium Nitrate + Sulfuric Acid
[tex]HNO_3 + Na_2SO_4[/tex]⇒ [tex]NaNO_3 + H_2SO_4[/tex]
To balance the above equation we need to add a coefficient of 2 in front of nitric acid on the right-hand- side and a coefficient of 2 in front of sodium nitrate on the left-hand-side.
∴ The balanced equation is as follows -
[tex]2HNO_3 + Na_2SO_4[/tex] ⇒ [tex]2NaNO_3 + H_2SO_4[/tex]
