0.16 gm hydrogen form 1.45 gm water on reaction with oxygen.Show that these results are in accordance with the law of reciprocal proportion.

0.76 gm MgO is obtained from 0.46 gm Mg.Show that these results are in accordance with the law of reciprocal proportion.

Two oxides of a metal, M were heated separately in hydrogen. The water obtained in each case were carefully collected and weighed. It was observed that- (1) 0.725g of the first oxide gives 0.18g of water and (2) 2.86g of the second oxide gives 0.36g of water. show that these results are in acccordance with the law of multiple proportions.

Ammonia contains 17.65% of hydrogen, water contains 11.11% of hydrogen and nitrous oxide contains 36.36% of oxygen. Show that these data illustrate the law of reciprocal proportions.

5g of pure MgO (obtained by reaction of metallic magnesium with oxygen) contains 3g of Mg. again 8.5 g of pure MgO (obtained by heating MgCO_(3) ) contains 5.1g of Mg. show that these results are in accordance with the law of constant proportions.

Copper gives two oxides. On heating one gram of each in hydrogen, we get 0.888g and 0.798g of the metal respectively. Show that these results are in agreement with law of multiple proportion.

Three elements X, Y and Z form three different compounds XY, YZ, and XZ. If XY contains 75% X, XZ contains 72.76% Z and YZ contains 11.11% Y, then show that these results illustrate the law of reciprocal proportion.

In two compound of hydrogen and oxygen, hydrogen present in 42.9% and 27.3% respectively. Show that the date support the law of multiple proportions.

In two comounds of hydrogen and oxygen hydrogen present is 42.9% and 27.3% respectively. Show that the data support the law of multiple proportions.

Two compounds A and B consist of tin and oxygen. Compound A contains 78.77% of tin and 21.23% of oxygen while compound B contains 88.12% of tin and 11.88% of oxygen. Show that these data illustrate the law of multiplee proportions.

An element reacts with hydrogen to form a compound A, which of reaction with water liberates hydrogen again. The element is -
