(a)
Interpretation:
The reaction

Oxidation:
Loss of electrons from an atom ion or molecule during a
Example
Here
Oxidation number:
It is the charge of an atom, provided if the compound is composed of ions. On oxidation the oxidation number will increase and on reduction the oxidation number will decrease. It can be also called as degree of oxidation.
Example:
`
Oxidation number of
Oxidation number of
Oxidation number of
Oxidation number of
Here we can see that the oxidation number of copper is decreased and the oxidation number of magnesium is increased.
(b)
Interpretation:
The reaction
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. Reduction is gaining of electrons.

Here we can see that the oxidation number of copper is decreased and the oxidation number of magnesium is increased.
(c)
Interpretation:
The reaction
Concept Introduction:
Reduction:
It is the gaining of electrons. Oxidation number will decrease in this. Reduction can be also termed as addition of Hydrogen or removal of Oxygen.
Example:
The oxidation No of Zn is reduced.

- The concept of determining which reactant is limiting and which is in excess is akin to determining the number of sandwiches that can be made from a set number of ingredients. Assuming that a cheese sandwich consists of 2 slices of bread and 3 slices of cheese, determine the number of whole cheese sandwiches that can be prepared from 36 slices of bread and 51 slices of cheese.arrow_forwardWhich of the following is true for all exergonic reactions? Group of answer choices A. The reactions are nonspontaneous B. A net input of energy from the surroundings is required for the reactions to proceed C. Some reactants will be converted to products D. The products have more total energy than the reactants E. The reaction proceeds with a net release of free energyarrow_forwardWhich one of the following statements is completely TRUE? O When AG > 0, the reaction is BOTH product-favored (spontaneous) AND endergonic. When AG 0, the reaction is BOTH reactant-favored (nonspontaneous) AND endergonic. When AG > 0, the reaction is BOTH product-favored (spontaneous) AND exergonic. When AG > 0, the reaction is BOTH reactant-favored (nonspontaneous) AND exergonic. When AG < 0, the reaction is BOTH reactant-favored (nonspontaneous) AND exergonic.arrow_forward
