If two elements can combine to form more than one compound, the masses of one element that combine with a fixed mass of the other element, are in whole number ratio.
(a) Is this statement true?
(b) It yes, according to which law?
(c) Give one example related to this law.

Two elements sometimes can form more than one compound .

When two elements combine to form more than one compound the different masses of the elements combining with fixed mass of the other bear a simple ratio. Name the above law.

When two elements combine to form more than one compound the different masses of the elements combining with fixed mass of the other bear a simple ratio. Explain the above law by taking oxides of carbon.

This law was proposed by Dalton in 1803 . According to this law , if two elements combune to form more than one compounds ,the masses of one element that combine with a fixed mass of the other element, are in the ratio of small whole number. For exemple, hydrogen combines with oxygen to form two compounds ,namely, water and hydrogen peroxide. Here, the masses of oxygen (i.e, 16g and 32g) which combine with a fixed mass of hydrogen (2g) bear a simple raio, i.e, 16 :32 or 1 :2 . An element forms two oxides .In one oxide ,one gram of the oxide containd 0.5g of the element. In another oxide, 4g of the oxide contains 0.8g of the element . Show that these data confirm the law of multiple proportion.

N_(2) and O_(2) combine to form a number of compounds such as NO,N_(2)O,N_(2)O_(3),N_(2)O_(5) . Show that these follow the law of multiple proportion.
