Answer:
The correct answer is "5217 Cal".
Explanation:
The given values are:
Specific heat,
c = 3.76 cal/g°C
Mass,
m = 25.0 g
Initial temperature,
T₁ = 21.5°C
Final temperature,
T₂ = 77.0°C
Now,
The heat energy will be:
⇒ 
On substituting the given values, we get
⇒ 
⇒ 
⇒ 
Strong base will completely ionize in water while the weak acid will not
