An ideal gas undergoes a cyclic process as shown in Figure.


$$\Delta $$U_BC = $$-$$5 kJ mol^-1, q_AB = $$2$$ kJ mol^-1, W_AB = $$-$$5 kJ mol^-1, W_CA = 3 kJ mol^-1. Heat absorbed by the system during process $$CA$$ is :

The IUPAC name of the following compound is :

In the molecular orbital diagram for the molecular ion, N₂⁺, the number of electrons in the $$\sigma $$_2pz molecular orbital is :

A sample of $$NaCl{O_3}$$ is converted by heat to $$NaCl$$ with a loss of $$0.16$$ $$g$$ of oxygen. The residue is dissolved in water and precipitated as $$AgCl.$$ The mass of $$AgCl$$ (in $$g$$) obtained will be : (Given : Molar mass of $$AgCl=143.5$$ $$g$$ $$mo{l^{ - 1}}$$)
