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.

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.

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.

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.

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.

Name a compound of hydrogen and oxygen showing stronger acidic behaviour than water?

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.

XY_2 and X_2Y_3 are two compounds of the elements X and Y 0.15 mole of each of these compounds weigh 9.3 and 15.9 g respectively. Calculate the atomic masses of X and Y.

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.
