Answer:
10 moles of O2
Explanation:
Balanced Equation:
CH4 + 2O2=CO2+2H2O
Now,
According to Stoichiometry,
In the reaction,
1 mole CO2 is produced by 2 moles of O2
∴5 moles of CO2 is produced by (2 X 5) moles of O2
= 10 moles of O2
Therefore, to produce 5 moles of CO2, 10 moles of Oxygen is needed.
