Answer:
11 moles of oxygen are necessary to react completely with 5.5 moles of CH₄
Explanation:
The balanced reaction is:
CH₄ + 2 O₂ → CO₂
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction) , the following amounts of each compound:
- CH₄: 1 mole
- O₂: 2 moles
- CO₂: 1 mole
Then you can apply the following rule of three: If by stoichiometry 1 mole of CH₄ reacts with 2 moles of O₂, 5.5 moles of CH₄ reacts with how many moles of O₂?
[tex]moles of O_{2} =\frac{5.5 moles of CH_{4}* 2moles of O_{2} }{1 mole of CH_{4} }[/tex]
moles of O₂= 11 moles
11 moles of oxygen are necessary to react completely with 5.5 moles of CH₄
