Formula for water is H20 and there are 5 mol water. 2 mol of hydrogen per 1 mol water so 5 mol of water times 2 mol hydrogen will give you 10 mol of hydrogen.
Same process with oxygen except 1 mol of oxygen per mol of water. So 5 mol water times 1 mol of oxygen will give you 5 mol of oxygen.
A virus can effect the body significantly as with bacteria it’s not as harmful to the body.
Hello!
For this reaction: 2H
₂ + O₂ → 2H₂O
If 19 g of oxygen reacts completely,
you'll need 2,39 g of H₂
To calculate that, you need to use the following conversion factor, applying molar equivalences, reaction coefficients, and molar masses, to go from grams of Oxygen to grams of Hydrogen:
