Answer
See the answer below.
Work Step by Step
a) Too high
Less heat will be evolved since less moles will react, but you will divide by the same amount of moles.
b) Unaffected
Same amount of moles will react, same amount of heat will be evolved.
c) Too high
You believe there are more moles of calcium hydroxide than there really are.
d) Unaffected
This won't affect the reaction or the number of moles of calcium hydroxide you believe are in the solution.
e) Too high
The calorimeter will cool and you will believe less heat evolved from the reaction.
f) Same as E
g) Too high
You will believe less heat evolved from the reaction than the actual value.
