Question

C). If 0.5 mole of oxygen (0,) reacted with hydrogen (H2), how many mole of water (H,0) was produced

Answer 1

Answer:

For 0.5 moles of oxygen consumed, there will be 1.0 moles of H2O produced.

Explanation:

Step 1: Data given

Number of moles of oxygen (O2) = 0.5 moles

Suppose  H2 is in excess

Step 2: The balanced equation

O2 + 2H2 → 2H2O

Step 3: Calculate moles of H2O

For 1 mol of O2 we need 2 moles of H2 to produce 2 moles of H2O

For 0.5 moles of O2 we'll have 2*0.5 moles = 1.0 moles of H2O

For 0.5 moles of oxygen consumed, there will be 1.0 moles of H2O produced.
