Which of the following oxides is/are not amphoteric in character?

Q. (a) What are amphoteric oxides? Give two examples of amphoteric oxides.
(b) Choose the acidic oxides, basic oxides and neutral oxides from the following:
Na₂O; CO₂; CO; SO₂; MgO; N₂O; H₂O.
(c) Which of the following are amphoteric oxides:
MgO, ZnO, P₂O₃, Al₂O₃, NO₂

Q. Assertion :SnO is more reactive towards acid than $Sn{O}_2$ Reason: Both SnO and $Sn{O}_2$ are amphoteric oxides

Q. Classify the following oxides into acidic, basic and amphoteric.
$CaO$, $MgO$, $C{O}_2$, $S{O}_3$, $N{a}_{2}O$, $ZnO$, $A{l}_2{O}_3$, $F{e}_2{O}_3$

Q. Consider the following statements and arrange in the order of true/false as given in the codes:
$S_1$: Oxides of boron $\left(B_2{O}_3\right)$ and silicon $\left(Si{O}_2\right)$ are acidic in nature.
$S_2$: Oxides of aluminium $\left(A{l}_2{O}_3\right)$ and gallium $\left(G{a}_2{O}_3\right)$ are amphoteric in nature.
$S_3$: Oxides of indium $\left(l{n}_2{O}_3\right)$ and thallium $\left(T{l}_2{O}_3\right)$ are basic in nature.
$S_4$: Oxides of germanium $\left(Ge{O}_2\right)$ and tin $\left(Sn{O}_2\right)$ are acidic in nature.

Q. (a) Classify following oxides as neutral, acidic, basic or amphoteric:
$CO,B_2{O}_3,Si{O}_2,C{O}_2,A{l}_2{O}_3,Pb{O}_2,T{l}_2{O}_3$
(b) Write suitable chemical equations to show their nature.
