Extracting Iron

Question 1

Recall

• Recall that iron is extracted in a blast furnace

Answer 1

Iron is ectracted form iron ore in a huge container called a blast furnace.

blast furnace is a vertical furnace that produces liquid metals by the reaction of a flow of air introduced under pressure into the bottom of the furnace with a mixture of metallic ore, oxygen and coke (carbon)

Question 2

explain

• Explain displacement reactions

Answer 2

A displacement reaction is a reaction in which one element is substituted for another element in a compound.

Question 3

Determine

• Use the reactivity series to determine if displacement reactions will occur

Answer 3

Yes displecment reactiosn will occur in the blast furnace.

Question 4

Recall

• Recall the raw materials needed for the blast furnace

Answer 4

iron ore, coke (carbon) and limestone

Question 5

summarise

• Write the word equation to summarise the reaction occurring in the blast furnace

Answer 5

iron oxide + carbon monoxide → iron + carbon dioxide

Question 6

write

• Write word equations for displacement reactions

Answer 6

In the case of the extraction of iron - the starting compound is iron oxide and the starting pure element is carbon.

Iron oxide + carbon → iron + carbon dioxide
