Question

Liquid water (H_{2}*O) is formed when two gases, hydrogen (H_{2}) and oxygen (O_{2}) , react. Why are the properties of water different than those of the reactant gases?

Answer 1

When substances chemically combine, products with completely different properties form

Step-by-step explanation

The reaction between gaseous hydrogen and oxygen to form water is a chemical change. Hence, when substances (like that of gaseous hydrogen and oxygen) chemically combine, products (water) with completely different properties form.
