Answer:
B) exothermic.
Explanation:
Hello!
In this case, we need to keep in mind that exothermic reactions release heat, so they increase the temperature as the final energy is less than the initial energy; in contrast, endothermic reactions absorb heat, so they decrease the temperature as the final energy is greater than the initial energy.
In such a way, when a dissolution process shows off a negative enthalpy of dissolution, we infer it is an exothermic process due to the aforementioned; therefore, the answer is:
B) exothermic

Answer:
a) 1,737 kJ
b) -1,93 kJ
Explanation:
The standard free energy change (ΔG) can be determined using:
ΔG = -nFE
a) For the reaction:
Fumarate²⁻ + CoQH₂ ⇄ succinate²⁻ + CoQ
The transferred electrons are 2, As E=-0,009V:
ΔG = -2×96,5kJ/molV×-0,009V
<em>ΔG = 1,737 kJ</em>
b) For the reaction:
cytc1 (Fe²⁺) + cytc (Fe³⁺) ⇄ cytc1 (Fe³⁺) + cytc (Fe²⁺)
The transferred electron is n=1 and E=0,02V:
ΔG = -1×96,5kJ/molV×0,02V
<em>ΔG = -1,93 kJ</em>

Answer:
2) HClO3 is stronger because chlorine is more electronegative than iodine.
Explanation:
The more electronegative the element is the more strong or acidic it becomes.
Chlorine being more electronegative than Iodine makes it easier for it to pull the electron of hydrogen more strongly and hence has a higher tendency to release a H+ unit. Hence that makes it stronger.
