How much oxygen is required to oxidize 4 g of hydrogen?
September 7, 2021 | education
| The reaction of hydrogen with oxygen occurs in accordance with the following chemical reaction equation:
H2 + ½ O2 = H2O;
For the oxidation of 1 mole of hydrogen, 0.5 mole of oxygen is required.
Let’s find the amount of hydrogen.
M H2 = 2 grams / mol;
N H2 = 4/2 = 2 mol;
To burn this amount of hydrogen requires 2/2 = 1 mole of oxygen. The same amount of hydrogen oxide will be obtained.
Let’s find its volume.
One mole of gas under normal conditions fills a volume of 22.4 liters.
The oxygen volume will be equal to:
V O2 = 1 x 22.4 = 22.4 liters;
