Two substances X and Y are colourless gases and are formed by the combination of sulphur and oxygen. Substance X is obtained by the combination of `6.0 g` of sulphur of `6.0 g` of sulphur with `6.0 g` of oxygen. Substance Y is formed when `8.6 g` of sulphur and `12.9` of oxygen combine.
(a) What is the mass ratio of the elements in the two substances ?
(b) Which law of chemical combination does it support ?
(c) Give the statement of the law.

Text Solution

(a) In the substances X
Mass ratio of S and O `6:6 or 1:1`
In the substance Y
Mass ratio of `S and O` is `8.6 : 12.9 or 1 : 3//2 or 2:3`
(b) The ratio supports the law of Multiple Proportions
(c) For the statement, consult section `1.7`.
