3.  Concerned with identifying the identity of a substance  Or whether a specific substance is present  i.e. flame test, litmus tests

4.  Determining the quantity (mass or concentration) of a specific substance present in a sample.  i.e. titrations, precipitation mass

5.  Mass cannot be created or destroyed, it is merely rearranged in space, and changed into different types of particles.

6.  Quantitative analysis can be used to verify the law of conservation of mass

8.  Sometimes 1 of the 2 reactants is not completely used up in a chemical reaction…  That’s the LIMITING reagent!

9. 1. Write a Balanced Equation for the Reaction 2. Determine the 2 Reagents involved in the Reaction 3. Using your 2 givens, Separately solve for your unknown 4. The species that gives the smaller amount of your unknown is your Limiting Reagent 5. Use your Limiting Reagent to Figure out how much of your Excess Reagent will Actually React

11.  If 20.0mL of 3.0mol/L H 2 SO 4 (aq) is added to 15mL of 5.0mol/L KOH(aq), what mass of water can form?

12.  350g of KOH(s) is added to 1.00L of 6.0mol/L of H 3 PO 4 (aq). How many moles of which reagent is in excess?

13.  10.0L of nitrogen gas at 105kPa and 35C are mixed with 33.5L of hydrogen gas at 95.0kPa and 40C and ammonia gas is formed. What mass of ammonia gas will form?

14.  5.00g of NaOH(s) is added to 50.0mL of 1.25mol/L HNO3(aq). Calculate the mass of water that forms. Determine your Limiting and Excess Reagents. Finally, use your LR to determine how much excess reagent is present.
