Question

Write a chemical equation for reduction of metal oxides with carbon ?​

Answer 1

Explanation:

There are many examples of the reaction in which metal oxides react with carbon and reduction happens. The most simplified reaction is

2 Fe2O3 + 3 C → 4 Fe + 3 CO2

where Feric oxide reacts with carbon.

Usually feric oxide is brown to red in colour .

When the reaction happens, carbon dioxide in emitted and we get iron. The valency of iron has reduced from +3 in feric oxide to +2 in iron

Answer 2

Chemical equation:

Metal oxide + Carbon → Metal + Carbon dioxide

Explanation:

• Carbon is a non-metal which replaces the less reactive metals from their oxides.
• The extraction of metal takes place by heating process.
• Some of the metals that are extracted with carbon are zinc, iron, tin lead and copper. Some of the metals that cannot be extracted from carbon are aluminium, magnesium, calcium, sodium and potassium.
• The carbon dioxide is liberated during end of the process.
