Question

Show that water illustrates the law of constant proportions

Answer 1

(a) The elements present in each sample are hydrogen and oxygen only.

(b) The ratio of weight of hydrogen to the weight of oxygen is 1 8.

Hence, water illustrates the law of constant proportions.

Answer 2

Explanation:

The ratio by the number of atoms for water will always be H : O = 2 : 1. ... Thus, 18 g of water contains 2 g of hydrogen and 16 g of oxygen, or the ratio of masses of hydrogen to oxygen will always be 1:8
