Answer:

2441.9 Joules

Explanation:

This is a sensible heat change problem.

Energy = Specific Heat Capacity x Mass x Change in Temperature

To find the change in temperature, you need to use this formula: Temperature Final - Temperature Initial.

234.3 - 137.0 = 97.3

Energy = 1.65 x 15.21 x 97.3

Multiply that equation, and you get your answer! I hope this helps!

The pka of hf is 3.2 determine the pkb of hf?
Julli [10]

Well, first we must remember that

pK_{a}+pK_{b}=14

This is because

K_{a}*K_{b}=10^{-14}

-log(K_{a}*K_{b})=-log(10^{-14})\\-logK_{a}+-logK_{b}=-log(10^{-14})\\pK_{a}+pK_{b}=14

So then

pK_{b}=14-pK_{a}=14-3.2=1.8
