$\ce{Cu}$ reacts with $\ce{HNO3}$, though $\ce{Cu}$ cannot replace $\ce{H}$ due to its less reactivity. The reaction that takes place is not similar to a metal displacement reaction $\ce{(CuSO4 + Zn -> ZnSO4 +Cu)}$ which is where what you state applies (taking the electropositivity series into consideration). According to conditions, there are two ...

First of all, your reaction is wrong. $\ce{HPO3}$ does not exist as a single entity. It is actually a cylic molecule of formula $\ce{(HPO3)_n}$. The simplest such compound is $\ce{(HPO3)3}$ which is called trimetaphosphoric acid. See this answer for more details. So, what happens is that phosphorus pentoxide is very powerful dehydrating agent and can rip ...

The reaction given in options (a) and (b) are called formation of nitrate esters. The following nitrate ester is called "ethyl nitrate", Firstly, $\ce{HNO3}$ and $\ce{H2SO4}$ reacts to form the $\ce{E+}$. As we know, the former is relatively weaker acid than the latter, therefore $\ce{HNO3}$ donates $\ce{OH-}$ and neutralisation takes place, $$\ce{...
