The atoms that are oxidized and the ones that are reduced form the given compounds. Concept introduction: A reaction that involves both oxidation and reduction is known as a redox reaction . The oxidation state of the atoms is changed. This involves the exchange of electrons between the species. Reduction occurs when an atom of a molecule or ionic species gains an electron. Oxidation occurs when an atom of a molecule or ionic species losses an electron.

Interpretation Introduction
Interpretation: The atoms that are oxidized and the ones that are reduced form the given compounds.
Concept introduction:
A reaction that involves both oxidation and reduction is known as a redox reaction. The oxidation state of the atoms is changed. This involves the exchange of electrons between the species.
Reduction occurs when an atom of a molecule or ionic species gains an electron.
Oxidation occurs when an atom of a molecule or ionic species losses an electron.
(b)
Interpretation Introduction
Interpretation: A balanced form of the given chemical equation for the given reaction.
Concept introduction:
A balanced chemical equation is based on the law of conservation of mass for a closed system. According to this law, the mass of the products formed in a chemical reaction is equal to the mass of the reactants involved in the reaction.

Interpretation Introduction
Interpretation: The amount of sodium cyanide solution required to react with 40.0kg of rock that contains 2.00 % by mass of gold.
Concept introduction: The mass % of component is given by: Mass%ofacomponent=MassofthecomponentinthesolutionTotalmassofthesolution×100
Molarity is given by: M=NumberofmolesVolumeofthesolution
Thus, volume of solution is calculated by above formula.
