CHEM 103 - Final Exam Review Questions
With Correct Answers 2026
List the three temperature scales - CORRECT ANSWER -Fahrenheit, Celsius, Kelvin
Celsius to Fahrenheit - CORRECT ANSWER -F= 9/5 (C+32)
Fahrenheit to Celsius - CORRECT ANSWER -C=5/9(F-32)
Celsius to Kelvin - CORRECT ANSWER -K = C + 273
Kelvin to Celsius - CORRECT ANSWER -C=K-273
Fahrenheit to Kelvin - CORRECT ANSWER -K = 5/9 (° F - 32) + 273
constant-pressure calorimetry - CORRECT ANSWER -- calorimetry where the pressure stays
constant during the process eg coffee cup calorimetry
- q=mcdeltaT
Hess's Law - CORRECT ANSWER -- the overall enthalpy change in a reaction is equal to the sum
of enthalpy changes for the individual steps in the process
-> Product - Reactants
Bhor model - CORRECT ANSWER --> shows the electron ring (looks like an atom)
-> Delta E = -2.18 x 10^-18 (1/n^2 final - 1/n^2 initial)
