Found between h-f,o,or n

Question 17

Covalent network solids, macromolecules

Answer 17

Metalloids

Question 18

Answer 19

Metal-nonmetal

Question 20

Dipole -dipole

Answer 20

Attraction between polar molecules

Question 21

London forces

Answer 21

Extremely weak leading to low melting and boiling points

Found between non metals. S8,O2,h2 etc.

Question 22

Melting and boiling points

Answer 22

Depend on bond strength-hydrogen bond has very high melting and boiling points.
London forces very low

Question 23

Ideal gas

Answer 23

Considered to be point masses

No attractive forces between molecules

Question 24

Gas

Answer 24

Has no definite shape or volume
Undergoes diffusion
Exerts pressure
Is easily compressed due to molecules being far apart
Can be condensed into a liquid.

Question 25

Heating and cooling curve

Answer 25

No temp change during phase change Cooling-starts with gas ends in solid Heating-starts in solid ends in gas

Question 26

Saturated solution

Answer 26

Solutions with the max amount of solute dissolved in the solvent Equilibrium state Constant temp and closed system

Question 27

Unsaturated solutions

Answer 27

Less than the max amount of solute dissolved in solvent

Question 28

Supersaturated solutions

Answer 28

More than the max amount of solute is dissolved Unstable Can be changed by scratching the surface of container with file or adding a crystal of the solute

Question 29

Solute

Answer 29

The substance being dissolved

Question 30

Solvent

Answer 30

The dissolving agent and is usually the most abundant substance in the mixture

Question 31

How a solution forms

Answer 31

when water molecules collide against the surface of the solute, the solute bonds break and some h bonds in water break and new bonds form between the solute and water

Question 32

How does ionization energy vary

Answer 32

The energy required to move the most loosely bound electron to form a cation. Increases across periods, decreases down families

Question 33
