Answer:
Substances with high boiling points condense at the bottom and substances with lower boiling points condense on the way to the top. The crude oil is evaporated and its vapours condense at different temperatures in the fractionating column.

answer above
Answer:
- <em>The mole ratio of C₄H₁₀ and CO₂ is</em><u> 2 : 8, which simplifies to 1 : 4</u>.
Explanation:
The<em> mole ratio</em> is the relative proportion of the moles of products or reactants that participate in the reaction according to the chemical equation.
The chemical equation given is:
- 2C₄H₁₀ + 13O₂ → 8CO₂ + 10H₂O
Once you check that the equation is balanced, you can set the <em>mole ratios</em> for all the reactants and products. The coefficients used in front of each reactant and product, in the balanced chemical equation, tells the mole ratios.
In this case, they are: 2 mol C₄H₁₀ : 13 mol O₂ : 8 mol CO₂ : 10 mol H₂O
Since you are asked about the mole ratio of C₄H₁₀ and CO₂ it is:
- 2 mol C₄H₁₀ : 8 mol CO₂ , which dividing by 2, simplifies to
- 1 mol C₄H₁₀ : 4 mol CO₂, or
That is approximately .63620 grams.
