Answer:
We'll produce 10 moles of H2O if 5 moles of O2 are used
Explanation:
Step 1: Data given
Number of moles oxygen = 5.0 moles
Step 2: The balanced equation
2H2 + O2 → 2H2O
Step 3: Calculate number of moles of H2O produced
For 2 moles H2 we need 1 mol O2 to produce 2 moles H2O
For 5.0 moles O2 we'll need 2*5 = 10 moles H2 to produce 2*5 = 10 moles H2O
We'll produce 10 moles of H2O if 5 moles of O2 are used
Answer:
10 moles
Explanation:
The equation for the reaction is given below:
2H2 + O2 → 2H2O
From the equation above,
1 mole of O2 produced 2 moles of H2O.
Therefore, 5 moles of O2 will produce = 5 x 2 = 10 moles of H2O
Therefore, 10 moles of H2O are produced when 5 moles of O2 is used up.
