Answer:
1.0 mol of water will be produced.
Step-by-step 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.
