Answer:
Saturated = The solution cannot dissolve any more solute at a given temperature
2) Unsaturated = solution can dissolve more solute at a given temperature.
3) Supersaturated = Solution which has more solute than its saturated solution

Answer: isotopes
Explanation: I remember this from when I took honors chemistry, they are know as isotopes.
Answer:
B. Electrons are gained, so the oxidation number decreases.
Explanation:
Reduction is the <em>gain of electrons</em>.
Oxidation number is the charge that an atom <em>appears</em> to have when we count its electrons in a specific way.
Electrons have a negative charge so, if an atom gains electrons, its charge (oxidation number) becomes more negative. The oxidation number decreases.
If electrons are given off, the atom is being oxidized. Loss of electrons is <em>oxidation</em>.
Answer:
9.57
Explanation:
Given that:
Considering the Henderson- Hasselbalch equation for the calculation of the pOH of the basic buffer solution as:
![pOH=pK_b+log\frac{[conjugate\ acid]}{[base]}](https://tex.z-dn.net/?f=pOH%3DpK_b%2Blog%5Cfrac%7B%5Bconjugate%5C%20acid%5D%7D%7B%5Bbase%5D%7D)
So,
pH + pOH = 14
So, pH = 14 - 4.43 = 9.57
