The dipole moment in a water molecule Which statement about hydrogen bonds is NOT true? A) Hydrogen bonds account for the anomalously high boiling point of water. B) In liquid water, the average water molecule forms hydrogen bonds with three to four other water molecules. C) Individual hydrogen bonds are much weaker than covalent bonds. D) Individual hydrogen bonds in liquid water exist for many seconds and sometimes for minutes. E) The strength of a hydrogen bond depends on the linearit...

Acid : proton donor base : proton acceptor conjugate base : what is left after an acid gives up a proton Strong acids : HCl, HBr, H2SO4, HI, HNO3, HClO4 strong base : group 1 hydroxide (NaOH, KOH, Ca(OH)2) strong acids have 2 | P a g e : weaker conjugate base weaker acids have : stronger conjugate bases weaker bases : resonance, more electronegative groups buffer : equal amounts of acid and base, pH=pKa equivalence of strong acid and strong base : equal mols of acid and base...

CEM 142 MOCK EXAM 2 QUESTIONS AND ANSWERS ALREADY PASSED Imagine a reaction in which compound A (which is a blue compound) reacts with compound B (which is a yellow compound) to give AB. A2 + B2 --> 2AB What can you say about the color of compound AB? It is impossible to predict what the color of AB is from the information given Which acid is the strongest of CH4 NH3 OH2 and HF HF because H and F are small atoms - more bond overlap, not willing to share electrons, most positive ...

there is a decrease in products - if K <<<< 1 of a weak acid, then (concerning products) decrease in pH - an increase in K and products will result in (concerning pH) Ka - equilibrium constant for ionization of acid increases - if the percent ionization increases, what happens to acid strength? K decreases - what happens to K as you deprotonate acids? weaker - do acid become weaker or stronger as you deprotonate them? no - do SA/SB have conjugates?
