5.06g of pure cupric oxide on complete reduction by heating in a current of hydrogen gave 4.04g of metallic copper. 1.3g of pure metallic copper was completely dissolved in nirtic acid and the resultant solutionwas carefully dried and ignited. 1.63g of cuo were produced in this process. show that these results illustrate law of constant proportions
