Answer 10

Sr

Question 11

How to determine what bond is the most polar

Answer 11

elements bonded furthest away from each other on the period table

Question 12

difference between a strong and weak acid

Answer 12

strong acids completely ionize, weak acids only partially ionize

Question 13

ph formula

Answer 13

pH=-log[H+]

Question 14

Ka formula

Answer 14

Ka=[H+][A-]/[HA]

Question 15

pKa formula

Answer 15

pKa=-logKa

Question 16

pH formula with pKa

Answer 16

pH=pKa + log [base(A-)/acid(HA)]

Question 17

Note

Answer 17

Water molecules are polar molecules and form hydrogen bonds. Oil is nonpolar therefore water molecules do not form strong attractions to oil.
