This homework assignment involves answering questions about inorganic compounds and balancing chemical equations. Students are instructed to show their work, be neat and clear, and the homework is due on October 31st, 2011. The questions include identifying mystery compounds based on descriptions, balancing and naming reactions, and identifying the type of reaction. Students must follow directions carefully to receive full credit.

1. Homework 2
Answer the following questions.
Follow directions and show all of your work to avoid point deductions.
Please be as neat and orderly as possible, as well as clear about your answers
and work.
I will not grade any homework that is not understandable, messy, or incomplete.
Homework is due, Monday October 31st, 2011
I. Read the following statement. Find the mystery compound or compounds
using the descriptions given. Write the name of the compound (using IUPAC
rules), its formula, classification of inorganic compound, and the type of bond that
hold the compound together.
1. I have two compounds that belong to the same period. Their valence electrons
are found in the 4s orbital but at times use their 3d orbitals to make bonds. The
oxidation state of one of the elements can be either +2 or +3. I have it as a solid
and will be using it in a +2 oxidation state. Lack of this compound in the blood
can cause humans to have anemia. The second compound is a metal oxide or
ternaryoxisalt. The metal has an unfilled 9 electrons in its d orbital, and the other
two elements are two nonmetals that belong in the same family. One of them has
an average atomic mass of about 16, and the other is found as an oxyanion with
the latter.
II. Complete the reactions below. Balance the equation and identify the type of
reaction. Name each of the compounds in the reaction using the IUPAC Rules.
1. Iron in the product will have an oxidation state of +3
Fe (s) + Cl2(g)______________ (s)
2. The oxidation state of copper in this compound is +2
Cu(s) + AgNO3 (aq)  ____________ (aq) + Ag (s)
3.
__________ (aq) + Al_____ (aq)  PbCl2 + Al(NO3)3

2. 4.Ba(OH)2is heated.
Ba(OH)2 (s)  _________ (aq) + H2O (l)
5.
Na2SO3 (aq) + HC2H3O2 (aq)  ___________(aq) + H2_____ (aq)
