Question

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

Answer 1

Answer:

The thermal decomposition of calcium nitrate

2Ca(NO3)2 → 2CaO + 4NO2 + O2

Explanation:

The thermal decomposition of calcium nitrate to produce calcium oxide, nitrogen dioxide and water. This reaction takes place at a temperature of over 600°C

Answer 2

Explanation:

) - given the stoichiometric coefficients, we know that 2 moles of Ca(NO3)2 will produce 4 moles of NO2, hence, 1 mole will produce 2 moles of NO2

2) - 328 g produces 22.4 L, since One mole of any gas at S.T.P. occupies the same volume which is 22.4 L.

Hence, 65.6 g produces (65.6*22.4)/328 = 4.48 L
