3/24 chemistry class update and homework due 3/31

Hi folks,

Today we primarily did a lab dealing with limiting reagents but we also spent a bit of time reviewing the math of limiting reagents and naming ionic compounds.

The latest quiz seemed to indicate that many folks haven't quite mastered the concept of naming ionic compounds so for homework this week I'd like you to do a bit more work on that by doing some naming as well as answering questions about today's lab.  Answers are included for the naming section.

1.  What was the limiting reagent in the first trial?  

2.  How much excess reagent did you have in the first trial?

3.  What was the limiting reagent in the second trial?

4.  How much excess reagent did you have?

5.  What was the limiting reagent in the third trial?

6.  How much excess reagent did you have?

7. In a perfect world, how much baking soda and vinegar would you need to yield 300 g of sodium acetate?

8. Name the following compounds.

a.  AgCl3

b. CrO

c. CaI2

d. Zn2Br2

e. Fe2O3

f. FeO2

g. SrI2

h. Zr(OH)2

i. V(NO2)2

j. Ag(SO4)

k. Mn(PO3)

Answers to Names

a.  Silver (III) Cloride

b. Chromium (II) Oxide

c. Calcium (II) iodide

d. Zinc (I) Bromide

e. Iron (III) Oxide

f. Iron (IV) Oxide

g. Strontium (II) Iodide

h. Zirconium (II) Hydroxide

i. Vanadium (II) Nitrite

j. Silver(II) Sulfate

k. Manganese (III) Phosphite
