CEM 141 FINAL EXAM 2026 LAB CHEMISTRY
AND SAFETY DRILL PACK ANSWER SHEET
◉ ion-ion interactions.
Answer: the strongest intermolecular interactions
ions have very high concentrations of positive and negative charge
charged particles
not in a specific spot
◉ To tell type of bond you look at.
Answer: electronegativities
◉ Simple Ionic Compounds.
Answer: Metal (cation & low electronegativity) and non-metal
(anion & High electronegativity)
◉ Why do simple Ionic compounds form between metals and non-
metals?.
Answer: Trade-off between the energy changes with
adding/subtracting electrons.
◉ Complex Ionic Compounds.
,Answer: contains polyatomic ions
◉ Polyatomic atom.
Answer: A charged group of covalently bonded atoms
◉ Monatomic gas.
Answer: One atom gas
◉ Temperature and Kinetic Energy of Monatomic gases are.
Answer: directly related
◉ At a specific temperature, do all gas particles move at the same
speed?.
Answer: No, collisions between particles transfer different amounts
of energy
◉ Can individual gas particles have a temperature?.
Answer: No, Temperature is related to average KE
◉ Population.
Answer: lots of particles
have temperature
, ◉ k_b.
Answer: Boltzmann Constant
◉ One molecule can have....
Answer: Kinetic Energy not temperature
◉ 1/2mv^2 equals.
Answer: 3/2k_bT
◉ If temperature increases then.
Answer: Average velocity will increase
◉ If velocity increases....
Answer: KE will increase
◉ Heisenberg Uncertainty Principle.
Answer: states that it is impossible to determine simultaneously
both the position and velocity of an electron or any other particle
◉ Particle of light, photons, electrons, protons and neutrons behave
as.
