Question

criss cross method of cuprous oxide


plz don't spam! ​

Answer 1

Answer:

yes I will the answer is

Explanation:

Cuprous is copper +1 cation (Cu

+1

), whereas cupric is copper +2 cation (Cu

+2

).

So, here valency of copper=2

Valency of oxide (O

2−

)=2

By applying crisscross method:

The formula will be CuO.

Answer 2

Copper with a lower valency (+1) is named as cuprous. It means if we take valency of copper and oxygen respectively 1 and 2 then by criss crossing the valency of copper and oxygen, we get the molecular formula Cu2O (called as Cuprous oxide since here the valency of Cu is one)

Answer : Cu2O
