The boiling points need to differ by 50 degrees to enable their complete separation ie of two different liquids. The separation occurs by first evaporation of one of the liquids and then its condensation and collection. It is a physical process not a chemical one.
Answer:
Explanation:
A = 54 since the trend per 2 on the X is 9 on the Y.
B. The relationship is linear. (Passes the vertical line test too)
It follows that the reaction is spontaneous at high temperatures Option A.
<h3>What is ΔS ?</h3>
The term ΔS is referred to as the change in the entropy of the system. Now recall that entropy is defined as the degree of disorderliness in a system. If a system is highly disorderly then it means that it has a high entropy. Also, ΔH has to do with the heat change that accompanies a reaction.
We know that both the entropy and the heat change can both either be positive or negative. Now we know that the equation ΔG = ΔH - TΔS can be used to ascertain whether or not a reaction will be spontaneous. If the result is negative, then the reaction will be spontaneous.
As such, when then it follows that the reaction is spontaneous at high temperatures Option A.

Answer: 0.374 mol CO2
Explanation:
We can calculate the number of moles of CO, n, required to produce the specified quantity of heat. This is done by dividing the required released heat, q, by the enthalpy of formation per unit mole of the substance, , based on the chemical equation, such that:
Therefore, 0.374 mol of CO2 must be reacted in order to produce 147 kJ of energy?
