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#...

Examine the stoichiometric formula.

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

Since equal volumes of gases contain an equal number of particles according to the Avogadro condition, stoichiometric equivalency requires adding half the volume of dioxygen.

The reaction between hydrogen and oxygen to form water occurs in a 2:1 ratio by volume. Therefore, to completely react with 2.4 liters of hydrogen, 4.8 liters of oxygen are required.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
