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
The equilibrium can be affected when there is a change of concentration, pressure or temperature of the system. Since it is mentioned that the temperature is constant, and the parameter being focused on is the initial amount, that should be the concentration factor. It depends where substance X is placed in the reaction. If it is a reactant (left side), then the equilibrium would shift and favor the forward reaction. If it is a product (right side), then the equilibrium would shift and favor the reverse reaction.
Yea so idk i'm just tryna get all the things done
bro wth this site is for legit questions not for people to do your homework for you lol
