1.	Copper forms two oxides following law of variable proportions. One gram of each oxide in hydrogen gas gave 0.799 g and 0.888 g of the metal respectively. Give the composition of these oxides.
Answer» SOLUTION :OXIDE (A) : weight of copper =0.799g weight of oxygen =0.201 G weight of metal per gram of oxygen =3.97g Oxide (B): WT of copper =0.888g weight of oxygen =0.112 g weight of metal per gram of oxygen =7.93g The ratio of weights of METALS reacting with same weight of oxygen =1:2 The oxides are CuO and `Cu_(2)O`
