The depictions of ionic compounds do not show distinct compound units but rather a collection of ions in the ratio given by the formula. Explain how the drawing of NaCl both illustrates that the compound exists as a large collection of ions and that the ratio of sodium ions to chloride ions is 1-to-1 as indicated by the formula NaCl.

Answers

Answer:

The ionic compound NaCl has a Face Centered Cubic unit cell

The site for atoms are Face, center and Edges corner.

Effective number of atoms

Na+

1centers + 12edges x(1)/(4) = 4 Na+  

Cl-

6face x(1)/(2)  + (1)/(8) x8 corners = 4Cl-

This is just one unit cell effective atom, there are thousand's of such unit cells are combined to form one such structure of NaCl. The real formula of NaCl is Na4Cl4 but for simplicity we use empirical formula that is NaCl.

In which of these substances are the molecules probably moving most quickly?solid iron at −45°C
solid iron at 300°C
liquid iron at 1600°C
liquid iron at 1800°C

Answers

The substance with molecules that are probably moving most quickly is liquid iron at 1800°C. This is because the particles of the liquid iron can move or slide past each other due to the small space available for movement. It cannot be compressed further due to the repulsive forces that acts between them. And also, the temperature is increases which causes for more thermal vibration of atoms.

What is the IUPAC name for the compound FeS?

Answers

The IUPAC name for the compound FeS is Iron(II)Sulfide. IUPAC stands for  International Union of Pure and Applied Chemistry. This is an organization that establishes official names of chemical elements and compounds. Hope this is the answer that you are looking for. 

Answer:

The correct answer is “Iron(II) sulfide.”

Explanation:

It is pretty obvious there is presented an iconic compound made by iron written as Fe and a sulfur, S that is a nonmental instead. A metal as iron will form a cation and a nonmetal an anion. The sulfur will need 2 electrons from iron in order to complete its octet and in this way the iron equilibrates the sulfur. It can give it 2, so that is why we write it in Roman numbers, and form the formula above.
