Answer:
It is considered an ionic compound since it is composed of the magnesium cation (Mg2+) and two hydroxide anions (OH-). There are no covalently shared electrons here. ... The reaction of the hydroxide anions with acid causes more of the magnesium hydroxide to dissolve until all of the acid has been neutralized.
The correct answer is false because there isn’t 4 there is 8 atoms
The best choice that explains why atoms of carbon-14 (c-14) are unstable is there are 2 more protons than neutrons in the nucleus
<h3>
What is a stable atom?</h3>
An atom is said to be stable if the number of neutrons in the nucleus is greater than number of protons in the nucleus, because the the neutrons increases the nuclear force which keeps the atom stable.
Thus, the best choice that explains why atoms of carbon-14 (c-14) are unstable is there are 2 more protons than neutrons in the nucleus.

Answer:
Explanation:
1. Atomic mass of K
To get the atomic mass of K, you calculate the weighted average of the isotopic masses.
That is, you multiply the atomic mass of each isotope by a number representing its relative importance (e.g., its percent of the total).
Set up a table for easy calculation:
2. Formula mass of KF
