Answer:
pH = 2.56
Explanation:
The Henderson-Hasselbalch equation relates the pH to the Ka and ratio of the conjugate acid-base pair as follows:
pH = pKa + log([A⁻]/[HA]) = -log(Ka) + log([A⁻]/[HA])
Substituting in the value gives:
pH = -log(1.77 x 10⁻⁴) + log((0.0065M) / (0.10M))
pH = 2.56
I believe it's D. A catalyst causes an increases the rate of a reaction without itself being consumed.
Precipitation is the short-term condition of the atmosphere
<h2>Increase of reaction rate</h2>
Explanation:
- It is observed that when the concentration of acetylcholine remains constant in the reaction of an aqueous solution, the speed of the enzyme-catalyzed reaction or the formation of the product increases with increasing concentrations of substrate.
- The reaction rate is directly proportional to the concentration of acetylcholine.
- At very low concentrations of acetylcholine, there is a small increase in the concentration of the substrate which results in a large increase of the rate in reaction.
Answer:
Wave energy is dissipated in quiet water areas like bays, resulting in sand deposition. Strong wave energy concentrates its power on the wave-cut cliff, eroding areas that stick out into the water. The wave erodes the cliff's bottom, eventually causing it to fall.
