Answer and Explanation
we are given the combustion reaction between oxygen and butane
the balanced reaction equation is:
2C₄H₁₀ + 13O₂ => 8CO₂ + 10H₂O
from the balance chemical equation, we see that 2 moles of butane react with 13 moles of oxygen.
if we have 5.5 moles of oxygen the we need:
2/13 x 5.5 = 0.85 moles of butane
the grams of carbon dioxide that will be produced if we react 3.5 moles of oxygen can be determined by first looking at the mole ratio from the balanced equation. we see that 13 moles of oxygen produce 8 moles of carbon dioxide
therefor the number of moles of carbon dioxide that will form from 3.5 moles of oxygen will be
8/13 x 3.5 = 2.15 moles
if we have 2.15 moles of carbon dioxide, we can determine the mass using the following reaction equation:
mass = n x m
where n is moles
M is molar mass of carbon dioxide
mass = 2.15moles x 44.01g/mole
= 94.62 grams
94.62 grams of carbon dioxide will be formed
