Question

What are the volumes of each gas in the resulting mixture after the combustion of 20 cm3lCO with 30 cm3lO2?

Answer 1

The volume of oxygen required is 0.50 dm3 . ... the ratio between the volumes of the reactant gases and the products ... The balanced equation for the combustion is.

Answer 2

For this problem, we can use Gay-Lussac's Law of Combining Volumes:

If pressure and temperature are constant, the ratio between the volumes of the reactant gases and the products can be expressed in simple whole numbers.
