Classify each of the following as either a p-type or n-type semi-conductor

(a) It is an example of substitution reaction as in this reaction the bromine group in bromoethane is substituted by the –SH group.  (b) It is an example of addition reaction...

Homogeneous mixture - soda water, air, vinegar, filtered tea.  Heterogeneous mixture - wood, soil.

The energy gap between the valence band and conduction band in an insulator is very large while in a conductor, the energy gap is very small or there is overlapping...

In metals with increase of temperature, the kernels start vibrating at faster rate and thus offer resistance to the ow of electrons. Hence, conductivity decreases. In case of semi-conductors, with...

(i) Ge (a group 14 element) is doped with In (a group 13 element). Therefore, a hole will be created and the semiconductor generated will be a p-type semiconductor.  (ii) B (a...

Let U be the set of all students in the group. Let E be the set of all students who know English. Let H be the set of all students who know...

(d) In gaseous state the HCl is covalent in nature while in aqueous solution it ionises to give H+ and Cl- ions

(a) outside the cable

(a) Task 1 can not be assigned to either person 1 or 2 i.e. there are 4 options. Task 2 can be assigned to 3 or 4 So, there are only 2 options...
