Answer:
BeCO3 will hydrolyze in an aqueous medium, yielding a basic solution.
Explanation:
In accord with the rules of salt hydrolysis, the cation 
can hydrolyze. The anion 
can also hydrolyze, given that the resulting conjugate acid is weak.
Given that both ions hydrolyze, the Ka (acid ionization constant) and Kb (Base ionization constant) of each reactant (or product [that is, the conjugate acid and base for each ion]) must be compared.
Using the web (hopefully some sort of reference table has been provided to you):
Ka (for Be^2+) = 
Kb (for CO3^2-) = 
= 
= 
The Kb > Ka, so the solution will be basic.
Hope this helps! My apologies if this answer is incorrect, I have not done this type of problem in a while.
<span>In the distant future, earth was no longer habitable by humans due to extreme pollution and excessive waste. Humans were not allowed to go back to earth due to the severity of the planet's condition and they dwell in space for hundreds of years while WALL-E, short for Waste Allocation Load Lifter Earth-class, was the only robot left to clean the planet, little by little.</span>
