Answer: If a reaction releases 675,000 Joules then it means it releases 161.328872 kcal.
Explanation:
According to the standard conversion,

Therefore, 675,000 Joules will be converted into kcal as follows.

Thus, we can conclude that if a reaction releases 675,000 Joules then it means it releases 161.328872 kcal.
Answer:
HCl will dissociate more fully and produce more H₃O⁺ ions.
Explanation:
HCl is strong acid and it dissociate fully and produce more H₃O⁺ ions as compared to the HF.
Although H-F is stronger bond as compared to the HCl but stability of product also count, and fluorine ions F⁻ which are formed after dissociation are not more stable as Cl⁻ ions.
Both F⁻ and Cl⁻ are carried -1 charge, but in case of chloride ions negative charge is spread over large surface area while in case of fluorine it is restricted to small surface. Thus F⁻ are becomes unstable.
Thus in dissociation equilibrium is shifted to wards HF and cause lower dissociation.
