What is the correct order of acidic strength for $Al_2O_3$,$SiO_2$,$P_2O_3$,and $SO_2$?

The chemical properties of $Li$ and $Mg$ are similar because:

If $X(OH) > Y(OH)$ (acidic strength) and $X$ and $Y$ both belong to the same group,then select the $CORRECT$ statement:

If $M^{+3}$ has configuration $[Ar]3d^{10}$,then $M$ belongs to :-

The periodic table consists of $18$ groups. An isotope of copper,on bombardment with protons,undergoes a nuclear reaction yielding element $X$ as shown below. To which group,element $X$ belongs in the periodic table?
${}_{29}^{83}Cu + {}_{1}^{1}H \rightarrow 6{}_{0}^{1}n + {}_{2}^{4}\alpha + 2{}_{1}^{1}H + X$

Choose the correct order of acidic strength for $CO_2, CuO, CaO, H_2O$.
