Answer:
a. ΔΗ > 0, solution feels cold
Explanation:
Hello,
In this case, endothermic process are those in which we can find that the products have more energy than the reactants, therefore energy is absorbed, for which the following equation:
Must be greater than 0 (positive) thereby, for a solution process we find that the solution feels cold, in such a way, answer is a. ΔΗ > 0, solution feels cold.
Regards.
The answer I’m sure it’s c
Answer:
C2H4
Explanation:
The image attached shows a detailed solution of the above problem. The empirical formula shows the ratio of the atoms of each element present.
Due to the lack of information provided, the best I can give you is this:
In Chemistry, the letter c most commonly refers to specific heat, which is present in the ratio J/g°C.
Hope it helps :)
