Question

What happens when ca no3 2 is heating it gives CaO ,NO2 and 02

Answer 1

The balanced equation of the reaction is below.

Step-by-step explanation:

2Ca(NO3)2 -----> 2CaO + 4NO2 + O2.

Answer 2

balanced equation:

2Ca(NO3)2 (aq)-----> 2CaO (s) + 4NO2 (g) + O2 (g)

So heating 2 moles of Ca(NO3)2 gives 2 moles of CaO, 4 moles of NO2 and 1 mole of O2. This is a heat decomposition reaction. It gives a white precipitate (CaO), and brown pungent gas (NO2).
