Question

the decomposition of sodium bicarbonate is a ______reaction​

Answer 1

Answer:

At temperatures from 80–100 °C (176–212 °F), sodium bicarbonate gradually decomposes into sodium carbonate, water, and carbon dioxide. The conversion is faster at 200 °C (392 °F): 2 NaHCO3 → Na2CO3 + H2O + CO. Most bicarbonates undergo this dehydration reaction.

Explanation:

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.
