Question

Industrial chemists have to understand the chemistry of oxides.

For example, silicon dioxide is used in glass making and carbon monoxide is used in the
extraction of iron from iron ore.
(i) Explain how burning carbon in air can lead to the formation of carbon monoxide.
(2)
(ii) Write the balanced equation for the reaction between silicon and oxygen.
(2)

Answer 1

carbon monoxide can be formed due to incomplete combustion of carbon due to insufficient oxygen supply
