Somethings that are beneficial is its good for plants, if it is very fine ash it is able to break down and quickly dissolve into the soil.
The answer is sodium chloride.
Explanation:
Sodium chloride refers to table salt, and is the most abundant of salts found in seawater.
Answer:
Explanation:
The usefulness of a buffer is its ability to resist changes in pH when small quantities of base or acid are added to it. This ability is the consequence of having both the conjugate base and the weak acid present in solution which will consume the added base or acid.
This capacity is lost if the ratio of the concentration of conjugate base to the concentration of weak acid differ by an order of magnitude. Since buffers having ratios differing by more will have their pH driven by either the weak acid or its conjugate base .
From the Henderson-Hasselbach equation we have that
pH = pKa + log [A⁻]/[HA]
thus
0.1 ≤ [A⁻]/[HA] ≤ 10
Therefore the log of this range is -1 to 1, and the pH will have a useful range of within +/- 1 the pKa of the buffer.
Now we are equipped to answer our question:
pH range = 3.9 +/- 1 = 2.9 through 4.9

Answer:
Well yes and no
Explanation:
The molecules move, but in place. They are constantly vibrating, rotating and so forth.
Atoms do not move at all
