Chemicals from common salt — task. Science CBSE Homework Assignments, Class 10.

What will happen if a solution of sodium hydrocarbonate is heated? Give the equation of the reaction involved.

Sodium carbonate and carbon dioxide gas are formed.
Sodium carbonate and hydrogen gas are formed.
Sodium carbonate, water and carbon dioxide gas are formed.
Sodium carbonate, carbon dioxide and hydrogen gas are formed.

The equation of the reaction is,

\(2NaHCO_3 \rightarrow Na_2CO_3 + H_2\)
\(2NaHCO_3 \rightarrow Na_2CO_3 + H_2O + CO_2\)
\(2NaHCO_3 \rightarrow Na_2CO_3 + CO_2\)
\(2NaHCO_3 \rightarrow Na_2CO_3 + H_2 + CO_2\)
