Question

Sodium hydrogencarbonate on heating produces?

Answer 1

Sodium hydrogen carbonate (also known as sodium bicarbonate orbicarbonate of soda) has the chemical formula NaHCO3. When it is heatedabove 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: $Na_2CO_3$, $CO_2$ and $H_2O$

Explanation: On heating sodium hydrogen carbonate or sodium bicarbonate ($NaHCO_3$) undergoes thermal decomposition to yield products, sodium carbonate ($Na_2CO_3$), carbon dioxide ($CO_2$) and water ($H_2O$)

Thus 2 moles of sodium bicarbonate form 1 mole of sodium carbonate, 1 mole of carbon dioxide and 1 mole of water.

The balanced chemical equation is:

$2NaHCO_3(s)\rightarrow Na_2CO_3(s)+CO_2(g)+H_2O(g)$
