Short Answer

Expert verified
  1. ClO2
  2. N2O4
  3. K3P
  4. Ag2S
  5. AlN
  6. SiO2

Step by step solution

01

Writing individual atoms/molecules with their charge

\(C{l^ - }\)\({O^{2 - }}\)\({N^{3 + }}\)\({K^ + }\)\({P^{3 - }}\)\(A{g^ + }\)\({S^{2 - }}\)\(A{l^{3 + }}\)\({N^{3 - }}\)\(S{i^{4 + }}\)

02

Crisscrossing charges with elements present in the compound

After crisscrossing, we get

  1. ClO2

  2. N2O4

  3. K3P

  4. Ag2S

  5. AlN

  6. SiO2

In the following drawing, the green spheres represent atoms of a certain element. The purple spheres represent atoms of another element. If the spheres touch, they are part of a single unit of a compound. Does the following chemical change represented by these symbols violate any of the ideas of Dalton’s atomic Theory? If so, which one?

Each of the following compounds contains a metal that can exhibit more than one ionic charge. Name these compounds:

a. Cr2O3

b. FeCl2

c. CrO3

d. TiCl4

e.CoO

f. MoS2

Samples of compound X, Y, and Z are analyzed, with results shown here.

Do these data provide example(s) of the law of definite proportions, the law of multiple proportions, neither, or both? What do these data tell you about compounds X, Y, and Z?

Open the Build a Molecule simulation (http://openstaxcollege.org/l/16molbuilding) and select the “Larger Molecules” tab. Select an appropriate atoms “Kit” to build a molecule with two carbon and six hydrogen atoms. Drag atoms into the space above the “Kit” to make a molecule. A name will appear when you have made an actual molecule that exists (even if it is not the one you want). You can use the scissors tool to separate atoms if you would like to change the connections. Click on “3D” to see the molecule, and look at both the space-filling and ball and-stick possibilities.(a) Draw the structural formula of this molecule and state its name.(b) Can you arrange these atoms in any way to make a different compound?

Using the periodic table, classify each of the following elements as a metal or a nonmetal, and then further classify each as a main-group (representative) element, transition metal, or inner transition metal:

(a) cobalt

(b) europium

(c) iodine

(d) indium

(e) lithium

(f) oxygen

(h) cadmium

(i) terbium

(j) rhenium
