21
Q

What is the reactivity series?

A

A list of metals from the least to most reactive

22

What is the chemical formula for Sulfuric acid?

A

H2SO4

25
Q

What is the chemical formula for Hydrochloric acid(solution)/Hydrogen chloride (gas form)?

A

HCl

26

A

AlCl3

31
Q

What is the chemical formula for Calcium Hydroxide?

A

Ca(OH)2

32
Q

What is the chemical formula for Mgsulfate

A

MgSO4

33
Q

What is the arrangement of gases?

A

Far apart and random

34
Q

What is the movement of gases?

A

Quickly in all directions

35
Q

What happens to gases if the temp increases?

A

Kinetic energy of the particles increases, there will be more contact with the edge of the box and more collisions. the frequency of collisions increases between particles.

36
Q

What is a frequency?

A

How many collisions in a given time

37
Q

what happens to volume as you increase temp?

A

The volume is directly proportional to the temp. as the temp increases, so does the volume.

38
Q

what happens to pressure as you increase temp?

A

The pressure is directly proportional to the temp. as the temp increases, so does the Pressure.

39
Q

What happens to Pressure as you increase the volume?

A

The pressure of the gas is inversely proportioned to the volume. If pressure is high, the frequency rises and volume decreases.
If the pressure is low, the volume is high.
