1) State and explain Law of multiple proportions with example.
Answers
Answer:
1)the law of conservation mass states that, the mass can neither be created nor destroyed.
Explanation:
2)Antoine lavosier observed that,
Total mass of reactants =Total mass of product
3)example: when hydrogen gas burns and combines with oxigen to yield water ,the mass of water formed is equal to the mass of the hydrogen and oxygen consumed .
4) H2 + O ==> H2O
2g 16g 18g
Law of multiple proportion states that when two elements combine to form more than one compound the mass of one element which combines with a fixed mass of the other element will always be ratio of whole numbers
EXAMPLE :let us assume two molecules CO(carbon monoxide) adn CO2(carbon dioxide)
CO=12gm of carbon +16gm of oxygen
CO2=12gm of carbon +32gm if oxygen
Thus the ratio of mass of oxygen in the given two compounds is 16:32=1:2
Thus law of multiples is proved
