Answer:
Puddles of water seen after a rainstorm that are clouded with sediment suggest erosion is occurring whereas puddles of clear water are a sign of minimal erosion. Lighter colored soil seen overtime is also a sign of erosion but can be more difficult to identify.

This organism belongs to the kingdom eubacteria since this kingdom is characterized by the following features that are also present in streptococcus:
1. Unicellular organism.
2. prokaryotic.
3. presence of cell wall made up of peptidoglycans.

The ph of the buffer solution given after 0.750 mol of H⁺ have been added is; 4.34
<h3>What is the PH of the Buffer?</h3>
pKa = -log(Ka) = 4.20
[A⁻] = [NaC₇H₅O₂]
[HA] = [HC₇H₅O₂]
Concentration of NaC₇H₅O₂ in the preferred buffer solution is;
[132.8g/(144.11 g/mol * 300 mol)] * 1000 mL/1 L = 3.07 M
Formula for the PH here is;
pH = pKa + log [A⁻/HA]
Thus;
pH = -log(6.3 x 10⁻⁵) + log [3.07/2.31]
pH = 4.34
