Question

explain gay lussac's law of combining volumes

Answer 1

The law of combining volumesstates that, when gases react together to form other gases, and when all volumes are measured at the same temperature and pressure: The ratio between thevolumes of the reactant gases and the gaseous products can be expressed in simple whole numbers.

Answer 2

When gases react they do so in volumes which bears a simple whole number ratio to one another and to the volumes of the products, if gaseous, provided the temperature and pressure of the reacting gases and their products remain constant.
