CHEM 163 Final Study (CHEM 163 WWU) Questions And Answers Predicting if a solid will form - ANS-Compare Qsp (not @ eq.) to Ksp (@ eq.) 1. Qsp>Ksp: rxn favors reactants, solid will form 2. Qsp<Ksp: rxn favors products, solid will not form --Don't forget, Q is a rxn quotient, exclude pure substances, coefficients become exponents Eq. Const. Expression - ANS--Coefficients become exponents -exclude pure substances (l), (s). These do not contribute to eq. Strength of weak acids - ANS-Ka...

MCAT Organic Chemistry Exam Questions and Answers Instantaneous Dipole Moment - Answer-Exists in an otherwise nonpolar molecule. Occurs because the electrons in a bond move about the orbital and at any moment may not be distributed exactly between the two bonding atoms, even when the atoms are identical. London Dispersion Forces - Answer-Occur between two instantaneous dipoles; the weakest dipole-dipole force (vs. hydrogen bonds which are the strongest dipole-dipole forces). Wolff-Kishner...
