Answer:
20.67 kcal of energy is released.
Explanation:
It is given that, an exothermic reaction releases 86.5 kJ. We need to convet kJ to calories.
Since,
1 kcal = 4.184 kJ
So,
1 kJ = 0.239 kcal
For 86.5 kJ,
86.5 kJ = (0.239 × 86.5) kcal
86.5 kJ = 20.67 kcal
So, 20.67 kcal of energy is released.
Answer:
The answer to your question is: [H+] = 0.0016
Explanation:
Data
pH = 2.8
[H+] of the solution = ?
Formula
pH = -log [H+]
process
2.8 = -log [H+] then we get antilog
antilog (-2.8 ) = [H+]
[H+] = 0.0016
