Concept explainers
Interpretation:
From the given
Concept Introduction:
Oxidation:
Loss of electrons from an atom ion or molecule during a chemical reaction is known as oxidation. Oxidation state of atom ion or molecule will increase in this process. In simple it is the addition of oxygen.
Example:
Here
Reduction:
Gaining of electrons from an atom, ion or molecule during a chemical reaction is known as reduction. Oxidation state of an atom will increase in this process. In simple it is the addition of hydrogen.
Example:
Here
Redox reactions:
It is a type of reaction in which both oxidation and reduction happens simultaneously. One get oxidized and one get reduced
Example
Zn is oxidized and hydrogen is reduced here
Nonredox reactions:
It is a type of reaction in which no transfer of electrons from one reactant to another reactant.

Meanwhile, the carbon source is coal that contains 60% C and 7% ash, the remainder being volatile matter. 4,800 kg limestone and 5,850 kg coal are fed to the reactor, which produces a gaseous and a solid product. Some of the carbon become CO2 and CO, and all the volatile matter are gasified and join the gaseous product. All solid components join the solid product leaving the reactor. The first reaction is 95% complete and the second 90%. Determine the amount of the solid product and the percent purity of CaC2 in it using molecular balances.arrow_forward
