6g of a hydrocarbon on combustion in excess of oxygen produces 17.6g of CO_(2) and 10.8g of H_(2)O . The data illustrates the law of :

1 g of oxygen combines with 0.1260 g of hydrogen to form H_(2)O . 1 g of nitrogen combines with 0.2160 g of hydrogen to form NH_(3) . Predict the weight of oxygen required to combine with 1 g of nitrogen to form an oxide.

3g of a hydrocarbons on combusion in excess of oxygen produces 8.8g of CO_(2) and 5.4g of H_(2)O . The data illustrates the law of:

This law was given by, a French chemist , Joseph Proust. He stated that a given compound always contains exactly the same proportion of elements by weight. Proust worked with two samples of curpic carbonate- one of which was of natural origin and the other was synthetic one . He found that the composition of elements present in it was for both the samples as shown below: Thus, irrespective of the source, a given compound always contains same elements in the same proportion. The validity of this law has been confrmed by various experiments. It is sometimes also reffered to as Law of constant composition. Limitation: This law is not applicable if the compound is formed from different isotopes of an element . The two isotopes of carbon C-12 and C-14 form carbondioxide C^(12)O_(2) and C^(14)O_(2) . The ratio of C : O is 12 : 32 and 14 : 32 respectively .It is not a constant ratio. 6.488 g lead with 1.002 g oxygen to form an oxide. This oxide is also obtained by heating Pb(NO_(3))_(2) , It is found that % of lead in this oxide is 86.62 .Show that these date illustrate the law of definite proportions.

2.75 g of cupric oxide was reduced by heating in a current of hydrogen and the weight of copper that remained was 2.196 g. Another experiment, 2.358 g of copper was dissolved in nitric acid and the resulting copper nitrate converted into cupric oxide by ignition. The weight of cupric oxide formed was 2.952 g. Show that these results illustrate law of constant composition.
