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

Answer:
Temperature and Heat Temperature is the measure of the thermal energy of a substance. The hotter an object, the greater the motion of its particles, and the greater the thermal energy. Heat is the transfer or exchange of thermal energy caused by a temperature difference.

Answer:
B. Mixing a solute and a solvent
Explanation:
Hello,
In this case, solutions are defined as liquid homogeneous mixtures formed when two substances having affinity are mixed. It is important to notice that the two substances are known as solute, which is added to other substance that is the solvent. Therefore, answer is B. Mixing a solute and a solvent.
Notice that when two insoluble substances are mixed no solution is formed. Furthermore, if two solutes together or a solute and a precipitate are mixed, no liquid homogeneous solution is formed, as commonly solutes are solid, nevertheless, when liquid, one should have to act as the solvent.
Best regards.
Answer: v2=268.047mL
Explanation:
V1/T1=v2/T2
V1=693mL
T1=45°c to convert to Kelvin 273+45=318k
V2=?
T2=-150°c to convert to Kelvin
273-150=123k
693/318=v2/123
Cross multiply
318v2=693×123
V2=85239/318
V2=268.047mL
