Question

Write the chemical equation for action of heat on baking soda.​

Answer 1

Answer:

Sodium hydrogen carbonate (also known as sodium bicarbonate or bicarbonate of soda) has the chemical formula NaHCO3. When it is heated above about 80°C it begins to break down, forming sodium carbonate, water and carbon dioxide. This type of reaction is called a thermal decomposition.

Answer 2

Answer:

Sodium bicarbonate decomposes on heating to form sodium carbonate and CO2 and water.

Chemical Equation :

$\boxed {2NaHCO3 \longrightarrow \: Na2CO3 \: + CO2 + H2O \: }$
