2) Cr3(P1O3)2 
 
 
3) H1Br1
 
 
4) C3S2 
 
 
5) Sulfurous acid 
 
 
--------------------------------- 
Part II 
 
Balance the chemical reaction and give the correct type of reaction for the following: 
 
1) ___ Ca1Br2 + ____ Na3P1 ==> ____ Ca3P2 + ____ Na1Br1 
Type of Rxn:____________________ 
 
 
2) ___ Li3P1O4 ==> ____ Li + ____P + ____ O2 
Type of Rxn:____________________ 
 
 
3) ___ C8H18 + ____ O2 ==> ____ C1O2 + ____ H2O1 
Type of Rxn:____________________ 
 
 
---------------------------------- 
Part III Print out One Step/two Step graphic organizer ([http://www.tmcleod.org/Level1/Chem328IonicCompound/CPOneTwoStepMoleCalGtaphicOrgwithWorkSpace.pdf CP One Two Step Mole Calculation Graphic Organizer with Work Space]) and fill out form to get correct answer for the following problems. 
 
 
1. How many liter @STP of elemental nitrogen gas (N2 if I have 85.2g of this gas? 
 
 
2.

--------------------------------- 
Part IV 
 
Print out Stoichiometry graphic organizer ([http://www.tmcleod.org/Level1/Chem328ChemicalReaction/CPStoichiometryCalculationGraphicOrganizerwithWorkSpace.pdf CP Stoichiometry Graphic Organizer with Work Space]), fill in and answer correctly 
 
1) Using the balanced equation from question 1 in Part II above, how many grams of calcium bromide do I need to react to obtain 56.4grams of sodium bromide? 
 
2) Using the balanced equation from question 3 in Part II above, how many molecules of dihydrogen monoxide do I produce if I react 65.2grams of elemental oxygen (remember it is a diatomic element). 
 
 
 
Answers:
