In an experiment, 1.50 g of pure copper(...

In an experiment, 1.50 g of pure copper(II) oxide was reduced to pure metal by heating with pure carbon. In another experiment, 1.15 g of pure copper was treated with nitric acid and the product formed was heated strongly till no further change was observed. The mass of copper(II) oxide so formed was found to be 1.40 g. The mass of pure metal formed in the first experiment and the law followed are respectively

A

1.15 g and law of conservation of mass

B

1.50 g and law of constant proportions

C

1.23 g and law of constant proportions

D

2.47 g and law of multiple proportions.
