Answer:
Energy released = 
Explanation:
Amount of fissionable material = 2.5 kg
Mass defect = 0.10 % of fissionable material
Mass defect 

Where,
m = Mass defect in Kg
C = Speed of light m/s2

Now substitute the values in the above equation

Answer:
At equal concentration of HBCG and BCG^-, the colour is green. This colour first appears at pH = 3.8
Explanation:
HBCG is an indicator that is prepared by dissolving the solid in ethanol.
Since
Ka=[BCG−][H3O+][HBCG]When [BCG-] = [HBCG], then Ka = [H3O+].
If pH = 3.8
Ka= [H3O+] = -antilog pH = -antilog (3.8)
Ka= 1.58 ×10^-4
The answer is anion hope that helps
