Answer:
a. the pH is only determined by the concentration of B and no titrant is added to the solution yet
b. when acid is added to the weak base B it is converted to conjugal acid BH+
Explanation:
a. point labelled A is the starting point
b. point B is the equivalent point
Answer:
The answer to your question is 1137.45 kJ
Explanation:
Data
mass = 424 g
T1 = 22.6°C
T2 = 149°C
Clw = 4.184 J/g°C
Cv = 2.078 j/g°C
Latent heat = 2257 J/g
Process
1.- Heat of liquid
Heat = (424)(4.184)(100 - 22.6)
Heat = 137308.8 J
2.- Calculate latent heat
Latent heat = (424)(2257)
Latent heat = 956968 J
3.- Heat of vapor
Heat = (424)(2.078)(149 - 100)
Heat = 43172.5 J
4.- Total heat
Heat = 137308.8 + 956968 + 43172.5
Heat = 1137449.3 J = 1137.45 kJ
