<center><b>Answers at bottom of webpage</b></center><br> <br> <u><b>Part I</b></u><br> <br> Please indicate if the following is an acid (A), Molecular Compound (MC), or Ionic Compound (IC). Then give the correct chemical name or chemical formula for the following:<br> <br> 1) Barium sulfate<br> <br> <br> 2) Cr<sub>3</sub>(P<sub>1</sub>O<sub>3</sub>)<sub>2</sub><br> <br> <br> 3) H<sub>1</sub>Br<sub>1</sub> <br> <br> 4) C<sub>3</sub>S<sub>2</sub><br> <br> <br> 5) Sulfurous acid<br> <br> <br> ---------------------------------<br> <u><b>Part II</b></u><br> <br> Balance the chemical reaction and give the correct type of reaction for the following:<br> <br> 1) ___ Ca<sub>1</sub>Br<sub>2</sub> + ____ Na<sub>3</sub>P<sub>1</sub> ==> ____ Ca<sub>3</sub>P<sub>2</sub> + ____ Na<sub>1</sub>Br<sub>1</sub> <br> Type of Rxn:____________________<br> <br> <br> 2) ___ Li<sub>3</sub>P<sub>1</sub>O<sub>4</sub> ==> ____ Li + ____P + ____ O<sub>2</sub><br> Type of Rxn:____________________<br> <br> <br> 3) ___ C<sub>8</sub>H<sub>18</sub> + ____ O<sub>2</sub> ==> ____ C<sub>1</sub>O<sub>2</sub> + ____ H<sub>2</sub>O<sub>1</sub><br> Type of Rxn:____________________<br> <br> <br> ----------------------------------<br> <u><b>Part III</b></u><br><br> 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.<br> <br> 1. How many liter @STP of elemental nitrogen gas (N<sub>2</sub> if I have 85.2g of this gas?<br> <br> 2. How many grams of Mg<sub>1</sub>Br<sub>2</sub> do I have if I mass out 6.28 moles of this ionic compound? ---------------------------------<br> <u><b>Part IV</b></u><br><br> <br> 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.<br> <br> 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?<br> <br> 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).<br> <br> ----------------------------<br> <u><b>Answers</b></u><br> <br> Part I<br> 1.
