A

Between 2 atoms, 1 atom has lost an electron and the other has gained one

34

What is an atomic number?

A

The sum of electrons and protons (not neutrons) combined in an atom.
(Always the same amount of each)

35
Q

What is the atomic MASS number?

A

Number of protons and neutrons (electrons are light so don’t count)

R.E.M. MASS+Neutrons

36

A 
How much vapour?
Heavier than air?
Flammable?
Water reactive? 
Will water curtain reduce the vapours?
39
Q

Boiling point is?

A

Temperature at which a material becomes a Gas or vapour

40
Q

Vapour pressure is?

A

Measure of how volatile a substance is

Atmospheric pressure is 100kpa
Water 3kpa
Petrol 30-65kpa
Diesel 0.6kpa

41
Q

Vapour Density is?

A

Relative density of a vapour compared to Air

Air =1
Heavier than 1 =low lying vapour
Less than 1 = high lying vapour

42
Q

LEL is?

A

Lowest % of a substance in air which can be ignited

43
Q

What causes vapour pressure to rise?

A

Temperature / heat

44
Q

Flash point is?

A

Fireball 25m

Cylinder may propel 150m

Fragments 200m

46
Q

49
Q

If an “X” appears before a Hazard identification number (e.g X30 or X33 as an intensification of that hazard) on the top half of an orange panel, what does it mean?

A

X = react dangerously with water

(X=No water)

Zero after number is no intensification (e.g. What would be X3 or 3 would be 30 or X30)
