(a)
Interpretation:
The balanced net ionic equation of the reaction needs to be determined.
Concept introduction:
The balanced net equation is that equation which follows the law of conservation of mass. According to this law, total mass of reactant is equal to the total mass of product.
(b)
Interpretation:
The amount of gas produced in liters is to be determined.
Concept introduction:
The following formula will be used −
Here, P is pressure, V is volume, n is number of moles, R is Universal gas constant and T is temperature.
(c)
Interpretation:
The pH of the solution is to be determined.
Concept introduction:
The following formula will be used −
(d)
Interpretation:
The bonding in blue-colored ion is to be determined by using crystal field theory and valance bond theory.
Concept introduction:
The valance bond theory is defined as the theory which helps to determine the bonding between two atoms.
The crystal field theory is used to describe the degeneracy of electron orbital states.
(e)
Interpretation:
The reason for the case, when an excess of KCN is added to the solution, the color changes and paramagnetism of the solution decreases is to be determined.
Concept introduction:
The paramagnetism is based on the number of unpaired electrons as the number of unpaired electrons increases the paramagnetic behavior increases.
