C). if 0.5 mole of oxygen reacted with hydrogen (h2), how many mole of water (h20) was produced
from the reaction?

1 mol of water is produced in those conditions.

Explanation:

The reaction to produce water between H₂ and O₂ is this:

2H₂  +  O₂  →  2H₂O

We don't have the amount of hydrogen, so we have to think that is in excess.

Let's work with oxygen.

Ratio is 1:2

For 0.5 mole of oxygen, I will make the double of moles of water.

1.0 mol of water will be produced.

Explanation:

Step 1: Data given

Number of moles of oxygen (O2) = 0.5 moles

Step 2: The balanced equation

2H2 + O2 → 2H20

Step 3: Calculate moles of water (H20)

For 2 moles of H2 consumed, we need 1 mol of O2 to produce 2 moles of water (H2O)

For 0.5 moles of oxygen (O2) we'll have 2*0.5 = 1.0 moles of water (H20) produced

1.0 mol of water will be produced.
