Question

b) Compare the similarities and dissimilarities of the properties of Oxygen and Hydrogen with the properties of water?​

Answer 1

Explanation:

similarities of the properties of Oxygen and Hydrogen with the properties of water

They both exist as simple (diatomic) molecules, and hence:

- have low melting and boiling points

- have low densities

- are colourless  and odorless gases

As for chemical properties, both are able to combine with metals, to form ionic compounds, or other non-metals, to form covalent compounds.

dissimilarities of the properties of Oxygen and Hydrogen with the properties of water

Hydrogen gas is highly combustible in nature but it does not support combustion.For example, fill a glass jar with hydrogen gas and turn it upside down. Introduce a burning candle near the mouth of the jar. The gas at the jar burns but the burning candle gets put off. This shows that hydrogen gas is combustible but does not support combustion.

Where in oxygen gas, is the one which makes combustion possible. And when these two gases combine together, they no longer possess their individual properties, because they form a molecule. Properties of water are implied due to hydrogen bond and not because of hydrogen and oxygen gases.
