Question

How many liters of oxygen are required to react completely with 2.4 liters of hydrogen to form water?

Answer 1

Why...`1.2*L`...

Explanation:

Look at the stoichiometric equation...

`H_2(g) + 1/2O_2(g) rarrH_2O(l)`

Given the Avogadro condition, equal volumes of gases contain an equal number of particles, stoichiometric equivalence demands addition of HALF the volume of dioxygen.
