Chapter 2: Q58E (page 127)

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

a. NiCO3

b. MoO3

c.Co(NO3)2

d. V2O5

e. MnO2

f. Fe2O3

Short Answer

Expert verified

a. Nickel Carbonate

b. Molybdenum trioxide

c. Cobalt nitrate

d. Vanadium (V) oxide

e. Manganese (IV) oxide

f. Iron (III) oxide

Step by step solution

01

Understanding the concept of ionic charges.

Generally, a large number of metals exhibit the property of showing multiple positive charges or ionic states. This property depends upon the entity forminga bond with the metal.The metal loses its electron according to the requirement of electrons by the other entity.

For example, Iron (Fe) can show two ionic states, i.e., +2 and +3

02

Determining the names of the compounds

(a)NiCO3= Nickel Carbonate

This is an ionic form ofNi2+andCO32-

(b) MoO3=Molybdenum trioxide

Molybdenum trioxide is the ionic form ofMo 6+three O2-ions.

(c) Co(NO3)2=Cobalt nitrate

Cobalt nitrate is an ionic form ofCo2+and two(NO3)-ions.

(d) V2O5= Vanadium (V) oxide

(e) MnO2=Manganese (IV) oxide

(f) Fe2O3=Iron (III) oxide

What are the IUPAC names of the following compounds?

  1. Manganese dioxide
  2. Mercurous chloride (Hg2Cl2)
  3. Ferric nitrate [Fe(NO3)3]
  4. Titanium Tetrachloride
  5. Cupric bromide (CuBr2)

Variations in average atomic mass may be observed for elements obtained from different sources. Lithium provides an example of this. The isotopic composition of lithium from naturally occurring minerals is 7.5% 6Li and 92.5% 7Li, which have masses of 6.01512 amu and 7.01600 amu, respectively. A commercial source of lithium, recycled from a military source, was 3.75% 6Li (and the rest 7Li). Calculate the average atomic mass values for each of these two sources.

Open the Build a Molecule simulation (http://openstaxcollege.org/l/16molbuilding) and select the 鈥淟arger Molecules鈥� tab. Select an appropriate atoms 鈥淜it鈥� to build a molecule with two carbon and six hydrogen atoms. Drag atoms into the space above the 鈥淜it鈥� 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 鈥�3D鈥� 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?

Use the build a molecule simulation (http://openstaxcollege.org/1/16molbuilding) to repeat Exercise 2.34, but build a molecule with three carbons, seven hydrogens, and one chlorine.

  1. Draw the structural formula of this molecule and state its name.
  2. Can u arrange these atoms to make a different molecule? If so, draw its structural formula and state its name.
  3. How are molecules drawn in (a) and (b) the same? How do they differs? What are they called (the type of relationship between these molecules, not their names)?

Use the periodic table to give the name and symbol for each of the following elements:

(a) the halogen in the same period as the alkali metal with 11 protons

(b) the alkaline earth metal in the same period with the neutral noble gas with 18 electrons

(c) the noble gas in the same row as an isotope with 30 neutrons and 25 protons

(d) the noble gas in the same period as gold
