Answer:
4.5 moles of carbon dioxide
Explanation:
Given parameters:
Mass of CH₄ = 72g
Unknown:
number of moles of CO₂ produced = ?
Solution:
To solve this problem, let us write the reaction equation first;
CH₄ + 2O₂ → CO₂ + 2H₂O
Now we know that O₂ is in excess and CH₄ is the limiting reactant that will determine the extent of the reaction.
Let us find the number of moles of CH₄ ;
Number of moles = 
molar mass of CH₄ = 12 + 4 = 16g/mol
Number of moles =
= 4.5moles
From the reaction equation;
1 mole of methane produced 1 mole of carbon dioxide
4.5 moles of methane will produce 4.5 moles of carbon dioxide
Answer:
A
Explanation:
You want one whole number to the left of the decimal. Depending on how many times u have to move the decimal over (in this case 7 times) determines the number you put after 10. And its -7 because to get it back to its original position you have to move left, which is a negative direction.
