State the Gay Lussac’s law of combining volumes, explain with an illustration.
Gay Lussac's law states that the volumes of the reacting gases bear a simple ratio, which is applied to the product when the product is also in the gaseous state. It also states that all the volumes are calculated under of temperature and pressure.
Example:
Step 1: Hydrogen combines with oxygen to form water
\(Hydrogen + Oxygen → Water\)
Step 2: \(H_2+1/2O_2→H_2O\) (Skeletal equation)
Step 3: \(xH_2(g)+O_2(g)→yH_2O(g)\) (Balanced equation)
Where, x and y, respectively are .
The ratio by volume which gases bear is which is a simple whole-number ratio.
It follows that the volumes of all gaseous reactants and products have a simple whole-number ratio to each other at a given temperature and pressure.
