FINAL EXAM CHM 151 RIO SOLADO M.SCHAAB LATEST UPDATE GRADED A+ What is the difference between an ionic bond and a covalent bond? An ionic bond is formed when one atom transfers electrons to another atom, creating ions that attract each other. A covalent bond is formed when two atoms share electrons. How do you determine the number of valence electrons in an element? The number of valence electrons can be determined by looking at the group number of the element in the periodic t...

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...

What is free energy? correct answers Energy available to do work What is the difference between exothermic and endothermic reactions? correct answers Exothermic releases heat, endothermic absorbs heat What is reaction coupling? correct answers Linking exothermic and endothermic reactions to drive unfavorable reactions What is Le Chetalier's Principle? correct answers System will shift to counteract stress How do you calculate free energy of coupled reactions? correct answers Add the...
