Propose a technological chain for the production of lead from the mineral galena PbS. Write down the reaction equations.
We will offer a technological chain for the production of lead from the mineral galena PbS. We write down the reaction equations.
The production of lead from the mineral galena PbS proceeds along the following chain.
Combustion reaction.
PbS -> PbO -> Pb.
2PbS + 3O2 = 2SO2 + 2PbO.
When lead sulfide interacts with oxygen, the result is sulfur oxide and lead oxide.
PbO + CO = Pb + CO2.
When lead oxide and carbon monoxide react, lead and carbon dioxide are produced.
That is, the production of lead proceeds in 2 reactions.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
