Question

an ore contains a mixture of zinc carbonate and lead carbonate. Zinc and lead are produced from this ore by 2 reactions.

REACTION 1: The carbonates in the ore are converted into a mixture of zinc oxide and lead oxide

Name this type of reaction. ______________________
How is this reaction done? _______________________

REACTION 2: the metals are mixed with carbon and heated in a furnace to produce zinc and lead

Explain why zinc and lead are produced

Answer 1

first reaction is decomposition reaction. carbonates are converted into respective oxides and CO2

while second reactions are reduction reactions
Each oxide is reduced by Carbon to give respective metal

Answer 2

Thank you so much!
