Transition Metals

Question 1

Explain what happens when transition metals loses its electrons.

Answer 1

Transition metals loses its electrons to form a positive ion. It loses 4s sub shell first before 3d to form a stable oxidisation state

Question 2

What do complex ions exist of?

Answer 2

complex ions consists of a central metal ion surrounded by ligands

Question 3

Explain what a ligand is.

Answer 3

molecule or ion that donates a pair of electrons to central transition metal ion to form a dative covalent bond

Question 4

what is Transition metals used as in the industry

Answer 4

Transition metals are industrial catalysts

Question 5

How are Platinum and Rhodium used in catalytic converters in cars? and how is this useful?

Answer 5

It converts carbon monoxide and nitrogen monoxide into carbon dioxide and nitrogen gas. Its useful because its not pollutant

Question 6

What is the role of iron in the Haber process?

Answer 6

used as a catalyst

Question 7

Explain what happens in the Haber process when using iron. Include how ammonia is produced

Answer 7

Nitrogen reacts with hydrogen to make ammonia. The iron catalyst speeds up the reaction by lowering the activation energy so N2 and H2 bonds are broken more easily

Question 8

Iron is used as a catalyst in the Haber process. How can this will with financial and environmental issues.

Answer 8

Cost of process are reduced.
Less fuel is needed to be burned and generate energy, this means that fossil fuels are conserved and less carbon emissions are produced

Question 9

What is the Haber process used for?

Answer 9

Haber process produces ammonia and this helps with making fertilisers to improve crop field
