The element that has a complete valence electron shell is argon (Ar) since it is a noble gas in the last group on the periodic table.
Answer:
a. At pH 9, the product, p-nitrophenol, will be ionized, the solution will appear yellow in color, and thus can be monitored at the wavelength of maximum absorption for the phenolate ion which is 400nm
Explanation:
In alkaline phosphatase assay, the hydrolysis of p nitrophenyl phosphate to p nitrophenol happens. When the ph is 9, the product which is p nitrophenol would undergo ionization. The solution is going to appear to be of yellow and it can be monitored at a wavelength for maximum absorption of phenolate ions at 400nm.
Option A is the answer to the question.

In hot water the molecules move faster versus In cold water they move slower (hope that helps)
The average kinetic energy of the gas particles is greater in container B because it has a higher temperature.
<h3>What is temperature?</h3>
The term temperature refers to a measure of the average kinetic energy of the molecules of body. This means that molecules that are at high temperature tend to move faster than the molecules that are at low temperature.
As such, the higher temperature of the molecules of the gas in B shows that the molecules in B are faster than those in A thus the correct statement is; "the average kinetic energy of the gas particles is greater in container B because it has a higher temperature."

Missing parts;
The picture shows two containers filled with a gas.
Two equally sized containers are shown with tight lids and each container has a thermometer. The container on the le is labeled A and the one on the right is labeled B. The thermometer inside container B shows a higher temperature than the thermometer inside container A.
Which statement is correct?
The average kinetic energy of the gas particles is greater in container A because it has a lower temperature.
The average kinetic energy of the gas particles is greater in container B because it has a higher temperature.
The gas particles in both containers have the same average kinetic energy because t have the same volume.
The gas particles in both containers have the same average kinetic energy because t have equal number of particles.
