Explanation:

There are three significant figures and it is best expressed in scientific notation

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.
