Solution

(A) Laughing Gas$$\longrightarrow$$ Nitrous oxide. As this gas sometimes generates a feeling of euphoria due to which a person wants to laugh after smelling it. (B) Anhydride of $$HNO_3 \longrightarrow$$ anhydride means a compound obtained after water has been removed from other compounds. From $$HNO_3, H_2O$$ can't be removed so, if we take $$2(HNO_3)$$ $$\longrightarrow H_2N_2O_6\quad \xrightarrow [-H_2O]{}\quad N_2O_5$$ (nitrogen penta-oxide) (C) Anhydride of $$HPO_3$$ Similarly as above if we take $$2[HPO_3]=H_2P_2O_6\quad \underrightarrow {-H_2O}\quad P_2O_5$$ (Phosphorus Pentaoxide) (D) Acid Anhydride of nitrogen. Acid Anhydride is formed by the combination of two acid structures with an ion of a water molecule. Hydrazine reacts with nitrous acid giving acid anhydride of nitrogen, i.e, hydrazoic acid with loss of $$2$$ molecules of water. $$N_2H_4+HNO_2\longrightarrow HN_3+2H_2O$$
