Beryllium oxide ($\mathrm{BeO}$) is an amphoteric oxide, meaning it reacts with both acids and bases.

Reaction with aqueous $\mathrm{HCl}$ (acid):
$\mathrm{BeO}+2\mathrm{HCl}\to {\mathrm{BeCl}}_2+{\mathrm{H}}_2\mathrm{O}$
The product is beryllium chloride (${\mathrm{BeCl}}_2$).

Reaction with aqueous $\mathrm{NaOH}$ (base):
$\mathrm{BeO}+2\mathrm{NaOH}\to {\mathrm{Na}}_2{\mathrm{BeO}}_2+{\mathrm{H}}_2\mathrm{O}$
The product is sodium beryllate (${\mathrm{Na}}_2{\mathrm{BeO}}_2$).

Thus, the products obtained are ${\mathrm{BeCl}}_2$ and ${\mathrm{Na}}_2{\mathrm{BeO}}_2$.

Answer: ${\mathrm{BeCl}}_2$ and ${\mathrm{Na}}_2{\mathrm{BeO}}_2$
