Question

Cu forms two oxides cuprous and cupric oxide which law can be
proved by the weight of cu and o?

Sujeet Kumar · Accepted Answer

Dear student 2Cu+O2=2CuO 4Cu+ O2=2Cu2O We know that mass of O=16u
& mass of Cu=63 5u In Cu2O& CuO if we fix the mass of
Oxygen as 16 then the ratio of mass of Cu in both the oxides will
be 2 63 5:63 5 127:63 5 which is 2:1 This is a simple whole number
ratio hence these compounds follow law of multiple proportion
