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.
answer: C
Explanation:
They are remains that are in rock
Answer:
An object which experiences either a change in the magnitude or the direction of the velocity vector can be said to be accelerating. This explains why an object moving in a circle at constant speed can be said to accelerate - the direction of the velocity changes.

Hello, and this is my own words Periodic trends are specific patterns in the properties of chemical elements that are revealed in the periodic table of elements. Major periodic trends include electronegativity, ionization energy, electron affinity, atomic radii, ionic radius, metallic character, and chemical reactivity.
Hope This Helps. and have good day!
