Q

Thermite reaction

A

A displacement or competition reaction between aluminium and iron oxide, producing aluminium oxide and iron. It releases enough heat to melt the iron, so it can be used for joining railway tracks together.

25
Q

Noble gases are stable because ..

A

They do not require any more or less protons.

26
Q

To be stable or unstable means

A

Its reactivity depending on the greater or lesser amount of atoms it needs to lose or gain.

27
Q

Metal +Acid =

A

Salt ( metal salt ) + hydrogen

28
Q

Different salts :

  • hydrochloric acids =
  • nitric salt =
  • sulphuric acid =
A
  • chloride
  • nitrate
  • sulphate
29
Q

Magnesium + hydrochloric acid =

A

35
Q

Chemical displacement is ..

A

The process of which a more reactive chemical replaces another.

36
Q

Example

A

Lead nitrate + potassium = potassium nitrate + lead

37
Q

Ores are metals found in rock underground , dug up through mining and extracted from different processes.

A

Any metal less reactive than carbon can be separated using carbon as it is any metal less reactive than carbon is less likely to react with anything else . Separating a metal with carbon means to heat it up-extracting the metal

38
Q

Gold is special..

A

It is the most least reactive therefore not able to deaerate as easily.-making it expensive .
