Answer the question on the basis of passage given below :
There are three kinds of amines which are primary, secondary and tertiary amines. These amines may have alkyl group or aryl group or both alkyl and aryl groups. These amines can be distinguished from one another by various chemical tests.
An amine A on treatment with \(\text{HNO}_2\) gives \(\text{N}_2\text{(g)}\) and an alcohol B. The molecular mass of alcohol B is 46.
The amine A is :

When electric current is passed through acidified water, 448 mL of hydrogen gas at STP is collected at the cathode in 965 seconds. The current passed in amperes is :

What is the formula of following coordination compound: Potassium trioxalatoaluminate(III)

Read the passage carefully and answer the questions.
Electrochemistry is the study involving two types of processes. One type involves the production of electricity from the energy released during a spontaneous chemical reaction. Galvanic cells like Daniel cells are used to produce electricity from the redox reaction. Nernst equation of a galvanic cell gives the relation between the standard cell potential and the concentration of the species involved in the redox reaction. The second type of study involves the cells in which electrical energy is used to bring about the chemical reactions in a non-spontaneous process. The conductance of electrolytic solution depends on many factors including the nature of the electrolyte and the dimensions of the electrolytic cell.
