How is nitrogen prepared in the laboratory? Write the chemical equations of the reactions involved.
Why does the reactivity of nitrogen differ from phosphorus?
Bond angle in `PH_(4)^(+)` is higher than that in PH3. Why?
Pb(NO3)2 on heating gives a brown gas which undergoes dimerisation on cooling? Identify the gas
Explain why NH3 is basic while BiH3 is only feebly basic.
Give the resonating structures of NO2 and N2O5.
What is the covalence of nitrogen in N2O5?
Why does NO2 dimerise?
