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.

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.

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.

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.

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.

In a mixture, two enantiomers are found to be present in 85% and 15% respectively. The enantiomeric excess (e,e) is

Carbon combines with hydrogen to form three compounds A, B and C. The percentage of hydrogen in A, B and C are 25, 14.3 and 7.7 respectively. Which law of chemical combination is illustrated ?

A mixture of hydrogen and oxygen at one bar pressure contains 20% by weight of hydrogen. Calculate partial pressure of hydrogen.
