If $100$ grams of pure water taken from different sources is decomposed by passing electricity. $11$ grams of hydrogen and $89$ grams of oxygen are obtained. Which chemical law is illustrated by this statement?

Open in App

Solution

This reaction illustrates the law of conservation of mass i.e. mass before the decomposition is the same as mass after the decomposition $(i . e . 89 + 11 = 100 g)$
The reaction is as follow:
$2 H_{2} O \to 2 H_{2} + O_{2}$
