Answer: 4.4 x 10^-7
Explanation:
The dissociation equation for this reaction is:
MgCO3 (s) → Mg+2 (aq) + CO3-2 (aq)
(Here 0.08 >>> x )
So the solubility MgCO₃ in a solution that containing 0.080 M Mg²⁺ is 4.4 x 10^-7
Molecules move from areas of high concentration to areas of low concentration.
Cells are the basic unit of structure in all organisms and also the basic unit of reproduction.
What is the this (^ that up there) a description of?
