The answer is Velocity and potential energy. Kinetic energy is the total energy of a system or an object in motion and requires movement.
Answer:
Explanation:
We are given two reactions which are the two steps of a mechanism:
......(1)
.......(2)
To determine the net chemical equation, we will multiply equation 2
.......(3)
Adding (1) and (3)
Thus, the net balanced chemical equation is:
Answer:
pH = 7.8
Explanation:
The Henderson-Hasselbalch equation may be used to solve the problem:
pH = pKa + log([A⁻] / [HA])
The solution of concentration 0.001 M is a formal concentration, which means that it is the sum of the concentrations of the different forms of the acid. In order to find the concentration of the deprotonated form, the following equation is used:
[HA] + [A⁻] = 0.001 M
[A⁻] = 0.001 M - 0.0002 M = 0.0008 M
The values can then be substituted into the Henderson-Hasselbalch equation:
pH = 7.2 + log(0.0008M/0.0002M) = 7.8
A scientific law states a repeated observation about nature.
