Law Of Constant Proportion

Law Of Chemical Combination ( रासायनिक संयोजन का नियम )|Law Of Conservation Of Mass (द्रव्यमान संरक्षण का नियम)|Law Of Constant Proportion (स्थिर अनुपात का नियम)|Law Of Multiple Proportion (गणित अनुपात का नियम)|Summary (सारांश)

Four different experiments were conducted in the following ways: I. 3 g of carbon was burnt in 8 g of oxygen to give 11 g of CO_2 . 1.2 g of carbon was burnt in air to give 4.2 g of CO_2 . III. 4.5 g of carbon was burnt in enough air to give 11 g of CO_2 IV. 4 g of carbon was burnt in oxygen to form 30.3 g of CO_2 . Law of constant proportions is not illustrated in experiment(s)

(a) State the various postulates of Dalton's atomic theory of matter. (b) Which postulate of Dalton's atomic theory can explain the law of conservation of mass ? (c ) Which postulate of Dalton's atomic theory can explain the law of constant proportions ?

Copper oxide was prepared by two different methods. In case, 1.75 g of the metal gave 2. 19 g of oxide. In the second case, 1.14 g of the metal gave 1.43 g of the oxide, show that the given data illustrate the law of constant proportions.
