CEM 142 MSU Final Exam Questions and Answers Already Passed Does aqueous sugar conduct electricity, why or why not No, because there are no ions Does aqueous NaCl conduct electricity? Yes, because this is an ionic compound (metal/nonmetal) What is the only IMF present in non polar molecules London Dispersion Forces How does electronegativity change in the periodic table Electronegativity increases from left to right (with the right being most electronegative), and increases from bo...

CEM 142 Exam 3 MSU Questions and Answers Rated A+ What do you know about reactions? (make a list) -Atoms are conserved. They are only re- arranged. -Properties of products are emergent (not a mixture of the reactants properties). -Reactions can be classified by the type of reaction (how it occurs). -Reactions are always accompanied by an energy change (can be exo and endo) that results from changed in interactions (bonds and IMFs) in the reactants and products. -Reactions are alway...

General Chemistry 2 ACS Final Review 25 Questions with Verified Answers What are the 4 types of intermolecular forces listed from weakest to strongest? - CORRECT ANSWER London dispersion, dipole-dipole, hydrogen bonding, ion-dipole What effect does IMFs have on surface tension? - CORRECT ANSWER surface tension increases as strength of IMF increase What effect does IMFs have on viscosity? - CORRECT ANSWER viscosity increases as strength of IMFs increase What effect does IMFs have on b...

Intermolecular forces (IMFs) correct answer: the forces of attraction between molecules of covalent compounds (weak) Intramolecular forces correct answer: forces within molecules. Forces caused by the attraction and repulsion of charged particles (strong) Dispersion forces correct answer: present in all molecules attractions between molecules caused by the electron motion on one molecule affecting the electron motion on the other through electrical forces; these are the weakest inter...
