Your question is inappropriate and unclear to read it. It doesn't make any sense.
Answer:
C
Explanation:
the gray moths were able to hide better in the smoky air then cream colored moth and were able to stay alive.
Answer:
C
Explanation:
Photosynthesis is usually represented by the equation Carbon dioxide + water + light --> glucose + oxygen.
Therefore, <u>A substance is water</u> and <u>B is glucose</u>
A is incorrect because it's talking about glucose
B is incorrect because it's talking about chlorophyll, the important pigment in photosynthesis
D is incorrect because it combines to form oxygen, not hydrogen
The ph of the buffer solution is 7.743.
What is the Henderson-Hasselbalch Equation?
The Henderson-Hasselbalch equation establishes a relationship between the pKa and pH of acids. When the concentration of the acid and its conjugate base and the associated conjugate acid, are known, the pH of a buffer solution can be determined with the use of this equation.
We use Henderson-hasselbalch equation,
pH = pKa + log [Base] / [Acid]
pKa = -log Ka = -log (3.0 x 10^-8) = 7.46
pH = 7.52 + log [0.250] / [0.150]
pH = 7.52+ 0.2227
pH = 7.743
Therefore, the ph of the solution is 7.743.
