Copper gives two oxides. On heating 1g of each in hydrogen, we get 0.888 g and 0.798 g of the metal respectively. Show that these results are in agreement with the Law of Multiple Proportions.

metal combines with oxygen to form two oxides, having the following composition: (i) 0.398 g of the first metal oxide contains 0.318g of metal. (ii) 0.716 g of the second oxide contains 0.636g of the metal. Show that the above data agrees with the law of multiple proportions.

A metal forms two oxides. The higher oxide contains 80 % metal. 0.72 g of the lower oxide have 0.8 g of higher oxide when oxidised. Show that the data illustrates the law of Multiple Proportions.

In experiment on the effect of heating on oxides of lead in a current of hydrogen the following results were obtained. Show that they are in agreement with the law of multiple proportions. a. 1.393 g of litharge (PbO) gave 1.293 g of lead b. 2.173 g of lead peroxide (PbO_(2)) gave 1.882 g of lead c. 1.712 g of red lead (Pb_(3) O_(4)) gave 1.552 g of lead

2.16 of copper metal when treated with nitric acid followed by ignition of the nitrate gave 2.70 g of copper oxide. In another experiment 1.15 g of copper oxide upon reduction with hydrogen gave 0.92 g of copper. Show that the above data illustrate the Law of Definite Proportions.
