My school, please we want you to correct this for examination sake
The correct option is D
Cu(NO3)2(s) = 2CuO(s) + O2(g) + 4NO2(g)
When copper nitrate is heated in the test tube, it decomposes into copper oxide, nitrogen dioxide and oxygen gas. Initially, a molecule of water is lost and on further heating, we get nitrogen dioxide and oxygen gas.
The chemical equation is -
heat
2Cu(NO3)2 → 2CuO+4NO2↑+O2↑
The two gases evolve as the reactant decomposes.
Therefore, the correct answer is D
haba myschool,i thought that the trioxonitrates of pb decopose to yield oxygen,nitrogen4oxide and anoda product cant remember....pls i stand to be corrected
