Using carbon to extract lead

-Represent displacement reactions with carbon, metal oxides and iron using formulas and equations.

-explain how mass is conserved in the extraction of metals.

What metals could be extracted using carbon?

SOURCE OF CARBON

Coke

-Burn coal slowly to temperatures over 1000 degree celcius.

-Absence of oxygen

REDUCTION

• REMOVAL OF OXYGEN FROM A METAL

• CARBON ACTS AS A REDUCING AGENT

Extraction of iron

• haematite (iron ore)

• Coke + limestone (remove impurities)

• Blast furnace - temp of upto 1650 degree celcius

• 4:15 to 5:15 GCSE BBC Science Bitesize - Useful Products From Metal Ores And Rocks - YouTube https://youtu.be/PvfnMxAJW_0

PREDICTING THE MASS OF IRON

• Iron oxide + limestone+ coke --> carbon dioxide + iron

• Predict the theoretical amount of iron produced

• Iron entering furnace = amount of ore x percentage purity = 100 tonnes x 0.2 = 20 tonnes

• Amount of ore going in = Amount of ore going out (CONSERVATION OF MASS)

Multiple Choice

Reduction is

• the removal of oxygen

• the addition of oxygen

Multiple Choice

Coke is made by

• buring coal at high temperature without oxygen

• buring coal at low temperature without oxygen

• buring wood at high temperature without oxygen

Multiple Select

In the extraction of iron, the following are needed...

• iron oxide

• coke

• limestone

• coal

Multiple Choice

Why is limestone added to the furnace when extracting iron?

• to make the temperature hot enough

• to supply carbon

• to remove impurities

Multiple Choice

To extract iron, a container is used. This is called

• an oven

• a blast furnace

• a fermenter

Multiple Choice

How much iron metal could be made from 250 tonnes of magnetite (iron ore) with a purity where 30 percents of its mass is iron?

• 250 tonnes

• 9 tonnes

• 75 tonnes

• 100 tonnes
