Front 3

Chemical bonds hold together___ in molecules or compounds

Back 3

atoms

Front 4

these bonds can result when atoms with the opposite charge attract

Back 4

Ionic bonds

Front 5

______Bond -
when atoms share one or more pairs of electrons or where atoms intract in other ways

Back 5

Covalent bonds

Front 6

Ionic
Covalent
Hydrogen
are examples of what

Back 6

chemical bonds

Front 7

____ bonds are formed by the attraction of oppositly charged ions

Back 7

Ionic bonds
ionic compounds tend to dissociate ( separate or go into solution) in water this is called ionization

Front 8

___ bonds form when atoms share 2 or more valance electrons

Back 8

Covalent bond
also shown at C-H
there are strengths single double, triple

Front 9

what is the term that describes the formation or breaking of chemical bonds

Back 9

Chemical reactions
chemical reactions are written with the reactant first, followed by the Products.

Front 10

what is the most important property of water

Back 10

the ability to form hydrogen bonds is the most important property.

Front 11

what are the differences between Polar/nonpolar?

Back 11

Polar covalent bonds unequal sharing of electrons (hydrophillic)
nonpolar- equal sharing of electrons (hydrophobic)

Front 12

cohesion and adhesion are-

Back 12

cohesion- when water molecules stick to other water molecules by hydrogen bonding ie surface tension
Adhesion- water molecules stick to other polar molecules by hydrogen bonding capillary action

Front 13

solute and solvent. what are the differences

Back 13

solute is what dissolves
solvent is what the solute disoloves in

Front 14

Back 16

lower (acidic)

Front 17

the Lower the H+ concentration the ______pH

Back 17

higher pH (basic)
