Which trihalide is not hydrolysed by water?

Options:
A NF3
B NCl3
C PCl3
D AsCl3

The correct answer is:
NF3

Solution:
In the first stage of hydrolysis, an extra bond is formed by water molecule. While chlorine and the group 15 elements (except nitrogen) can expand their octet by using vacant d-orbitals of the valence shell, F and N cannot. As a result, NF3 is extremely stable.
Trihalides of P, As, Sb and Bi hydrolyse readily.
NF3+H2O(l)→ No hydrolysis
NCl3+3H2O(l)→NH3+3HOCl
PCl3+3H2O(l)→H3PO3+3HCl
2AsCl3+3H2O→6HCl+As2O3
Notes: A. SbCl3 and BiCl3 also hydrolyze to form basic oxochlorides.
BiCl2+H2O⇌BiOCl+2HCl
B. Hydrolysis of NCl3 is thought to proceed by stepwise replacement of chlorine, the lone pair on N-atom bonding to hydrogen atom of a water molecule
NHCl2+H2O→NH2Cl+HClO
NH2Cl+H2O→NH3+HClO

Which two distinct microbial processes are responsible for the release of fixed nitrogen as dinitrogen gas $\left(\mathrm{N}_2\right)$ to the atmosphere?

Options:
A Aerobic nitrate oxidation and nitrite reduction
B Decomposition of organic nitrogen and conversion of dinitrogen to ammonium compounds
C Enteric fermentation in cattle and nitrogen fixation by Rhizobium in root nodules of legumes
D Anaerobic ammonium oxidation and denitrification

The correct answer is:
Anaerobic ammonium oxidation and denitrification

Solution:
Denitrification is a chemical process in which nitrates in the soil are reduced to molecular nitrogen $\left(\mathrm{N}_2\right)$ which is released into the atmosphere. It is done by denitrifying bacteria like Pseudomonas. Anaerobic oxidation of ammonium $\left(\mathrm{NH}_4\right)$ also releases nitrogen in the atmosphere.
Related Theory
Anammox (anaerobic ammonium oxidation), which is a reaction that oxidizes ammonium to dinitrogen gas using nitrite as the electron acceptor under anoxic conditions, was an important discovery in the nitrogen cycle.

Which two of the following changes $(1-4)$ usually tend to occur in the plain dwellers when they move to high altitudes $(3,500 \mathrm{~m}$ or more)?
(1) Increase in red blood cell size
(2) Increase in red blood cell production
(3) Increased breathing rate
(4) Increase in thrombocyte count Changes occurring are

Options:
A (2) and (3)
B (3) and (4)
C (1) and (4)
D (1) and (2)

The correct answer is:
(2) and (3)

Solution:
When a person moves to higher altitudes, the $\mathrm{P}_{\mathrm{O}_2}$ and total atmospheric pressure decrease. Hypoxia stimulates the JG-cells of the kidney to release erythropoietin hormone, which stimulates erythropoesis in bone marrow causing polycythemia. Hypoxia will also increase breathing rate. Initially the size of RBCs will also increase but with increase in number of RBCs, the size of RBCs becomes normal.
