The ratio of hydrogen and oxygen in water is 2 : 1 Let's work out the percentage of hydrogen and oxygen in water.

The ratio between hydrogen and oxygen in a carbohydrate is

Find the number of hydrogen and oxygenn atoms present in 0.09 g of water.

In water, the angle between the atoms of Hydrogen and one atom of Oxygen is

Ratio of hydrogen & oxygen in carbohydrate: a. 2 : 1 b. 1 : 2 c. 3 : 1 d. 1 : 3

The oxygen obtained from 72 kg of water is

0.30 g of a substance gives 0.88 g of carbon dioxide and 0.54 g water. Calculate the percentage of carbon and hydrogen in it.

There is a mixture of hydrogen and oxygen gases in a vessel. The root mean square speed of the oxygen molecules is
