Question

Copper(II) nitrate decomposes upon heating to form copper(II) oxide, nitrogen dioxide gas, and oxygen gas. If 1.0 mole of copper(II) nitrate decomposes, how many moles of nitrogen dioxide would be formed?

Answer 1

Cu(NO3)2 --> CuO + NO2 + O2 unbaslanced
now balance
2Cu(NO3)2 --> 2CuO + 4NO2 + O2
has 2 Cu
has 4 N
has 12 O good

so 4 mols NO2 for each 2 mols Cu(NO3)2
so twice as many
so 2

Answer 2

Worst

Answer 3

SO
Copper (II) nitrate is heated to form copper oxide nitrogen dioxide and oxygen gas.
