Acids and Bases

Question 1

Acids form what when dissolved in water?

Answer 1

H+ ions

Question 2

Bases release what when dissolved in water?

Answer 2

OH- ions

Question 3

Salts composition

Answer 3

Metals + anion

Question 4

If more than one binary compound is formed by a pair of non metals greek prefixes are used. What are they?

Answer 4

1=mono
2=Di
3=tri
4=tetra
5=penta
6=hexa
7=hepta
8=octa
9=nona
10=deka

Question 5

Percent Composition equation

Answer 5

part/whole x 100%=Percent composition and
mass of element x in 1 mol/mass of 1 mol of the compound x 100%

Question 6

ionic bonds?

Answer 6

Metals + non metals (cation and anion)

Question 7

Covalent bonds?

Answer 7

bond between 2 non metals

Question 8

Electronegativity definition and trend?

Answer 8

Ability to accept electrons (non metals love to accept electrons)-Increases L to R and Decreases down the group ^

Question 9

Lewis Configuration what goes in the middle?

Answer 9

Most metallic element

Question 10

Polar covalent bonds definition

Answer 10

2 different non metals

Question 11

non polar covalent bonds definition

Answer 11

2 same non metals (diatomic elements)

Question 12

Electronegativity range for bonds

Answer 12

0-.3 = non polar
.4-1.9 =polar
2.0+ = ionic

Question 13

What affects solubility in water?

Answer 13

Molecular polarity (Like dissolves like).

Polar molecules are attracted to polar molecules.
