Answer 1

$\huge\boxed{\fcolorbox{red}{yellow}{Shailesh}}$

Ea2O3 is the oxide of Eka-aluminium predicted by Mendeleeff. 2) EsO2 is the oxide of Eka-silicon predicted by Mendeleeff. 3) In 1875 Eka-aluminium was found to be Ga2O3 -Gallium oxide.

Answer 2

${\huge{\boxed{\mathbf{\red{♡ANSWER♡}}}}}$.

• ${EaO3}$ is the predicted formula of oxide of the predicted element in eka -Aluminium group.
• This is similar to${Ga2O3}$,the observed property of oxide of Galium ,which was discovered in 1875.
• ${EsO2}$ is the predicted formulaof oxide of predicted element eka-silicon group.
• This is similar to GeO2,the observed property of Oxide of Germanium , which was discovered in 1886
