Answer:
a. C (s)+ 02(g)---->C02(g)
b. CO2(g) +C(s)--->2CO(g)
Explanation:
This reaction is the method of purification of some precious metals such a iron(Fe) in it's ore. a.The carbon(coke) is oxidized to carbon (IV) oxide
b. the carbon dioxide gas is reduced with the same carbon to produce carbon(II) oxide.
The reaction may be referred to as a decarboxylation reaction. Decarboxylation reactions are those in which carbon dioxide is removed. This reaction in which pyruvic acid is connverted to acetyl coenzyme A is a part of the reactions that take place during the process of respiration. The carbon dioxide released during respiration is produced from such decarboxylation reactions.
