Enthalpy Change (Practical) Flashcards
1
Q
What prevents a calorimeter experiment from being completely accurate to the data book value?
A
> Heat Loss, usually caused by heat source or water being exposed to air (use coffee cup as a fix)
Incomplete combustion due to using oxygen in the air
2
Q
What is the purpose of calorimetry? (easy)
A
> To find enthalpy change (ΔH) [4]
> Enthalpy change (ΔH) is simply the change in energy per mole of a substance (kJ/mol) [5]

Q
Why shouldn’t you just measure initial and final temperature?
A
As the temperature is constantly changing throughout the experiment, the initial and final temperatures are inaccurate.
