Question

Copper and oxygen combine to form II oxide red Kapoor's offside CU 2 O and black copper oxide cuo show that these compounds follow the law of multiple proportion​

Answer 1

2Cu+O2=2CuO4Cu+ O2=2Cu2OWe 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 2.63.5:63.5127:63.5 which is 2:1This is a simple whole number ratio hence these compounds follow law of multiple proportions.

follow me !

Answer 2

$\boxed{Explained\:Answer}$

______________________________

★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

★ Therefore,This is a simple whole number ratio hence these compounds follow law of multiple proportions
