. If the Kelvin temperature of a sample of ideal gas doubles (e.g., from 200 K to 400 K), what happens to the root-mean-square speed, (a) increases by a factor of (b) increases by a factor of 2; (c) decreases by a factor of 2; (d) increases by a factor of 4; (e) decreases by a factor of 4.
Chemistry 222 final will be 70 questions. You will have 110 minutes. It will be in the same room we have had lecture all semester. Bring a pencil, non-programmable calculator, and an eraser. Dahl will provide a scantron. Exam is curved. Half of the questions right is a 70%. You will be tested over atomic and molecular structures, bonding, stoichiometry, equilibrium, redox reactions and electrochemistry, periodic table trends, and solutions. You will be provided with a periodic table, equations, and constants. You will not have to memorize these things (phew!). Things to review for the exam: Quantum numbers. The principle quantum number n=1,2,3,… It is the energy level. The outer energy level of potassium has a quantum number of 4. The subshell l=0,1,2,...,n-1.
