Part I : Showing appropriate work, give the correct chemical formula or chemical name for the following:

1a. Calcium nitrate

1b. Pb1(SO3)2

1c. N5Cl2

1d. Copper (II) carbonate

1e. Sn1S2

Part II Stoichiometry, Limiting Reactant and Percent Yield

1a. In a sentence, explain what a limiting reactant problem is and when do need to do one.

1b. Define limiting reactant:

Define excess reactant:

2. Solid lithium is added to a solution of calcium nitrate. If you start with 2.54grams of Lithium and obtain 7.90grams of solid calcium (after filtering and drying product), what is the percent yield of calcium?

Balanced Chemical Rxn:

Part III Predicting Reactions and Net Ionic Reactions

Follow directions in SingleReplacementDoubleReplacementHandout for showing work.

a. Al(s) + Zn1(C2H3O2)2 (aq) -->

b. (NH4)2(SO3)1 (aq) + Ca1Br2 (aq) --->

c. Ca1(NO3)2 (aq) + Al1Cl3 (aq) --->

Part IV Oxidation Reduction Reaction (Redox reactions)

Answer the following Redox reaction as stated in the following:

a. Cu(s ) + Ag1(NO3)1(aq) ---> Cu1(NO3)2(aq) + Ag(s)

b. Zn + HNO3 --> Zn(NO3)2 + NO2 + H2O1 (Yes, one N can be involved with reaction and other does not have to)

c. C2H6(g) + O2(g) ---> C1O2(g) + H2O1(g)
