Answer:
Explanation:
Hydrosulfuric acid (H_2S) is considered a 'weak acid." It dissociates in water according to this reaction: H_2 S(aq) + H_2O(t) HS^-(aq) + H_3O^+(aq) k_a = 9 times 10^-8 Hydroiodic acid (HI) is considered a "strong acid".
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.
No, they are both different
You'll need the specific heat capacity of aluminium to solve this question.
H=(0.005)(37-22)(specific heat capacity of aluminium)
