1 PG 84 Pg 84 Header: I can predict DR rxns using solubility rules
Hmwk: Finish lab. Mole Projects due next class Warm-up: Handshake each partner at your table. Best & Worst moments of spring break

2 MOLE PARTY! If you would like to bring food, please sign up on the sheet All food must be sealed in a package All drinks must be sealed You may drop off food in the morning starting at 8:15am Mole projects due when you walk in the door Make sure to have your grading rubric with your mole! All problems must be completed.

3 Double Replacement

4 Double Replacement Reactions
Ag+ NO-3 Na+ Cl- Rxn involves 2 compounds switching cations with each other

5 Come up with a list of soluble compounds.
Rally Partner: Person A gives and answer Person B gives an answer continuing until time is called Come up with a list of soluble compounds. Come up with a list of insoluble compounds.

6

7 Insoluble products precipitate out.

8 Practice __AlBr3(aq) + __K2SO4(aq) __Al2(SO4)3( ) + __KBr( )

9 Practice __KI(aq) + __Pb(NO3)2(aq)  __KNO3( ) + __PbI2( )

10 Cast Away: DR Lab Prep One person on your team will be cast off to check answers and get ideas. They will then bring you all their treasures they have for you to share

11 Cast Away: DR Lab Prep C: In your teams write all the chemical formulas for the lab R: Write a reaction that will form a precipitate from the chemicals above C: Write reaction #2 that forms a precipitate R: Write reaction #3 that forms a precipitate

12 DR Investigation Once all 5 rxns are written you may go to lab.
Please keep chemical trays clean (in fume hood) Wash hands when done with the lab Post lab analysis: Write balanced rxn with state signifiers. Draw the picture in the beaker. Must color coordinate

13 Prediction Silver nitrate and potassium chromate

14 __AgNO3(aq) + __K2SO4(aq) __KNO3( ) + __Ag2SO4( )
__FeCl3(aq) + __Na2CO3(aq) __Fe2(CO3)3( ) + __NaCl( )   __BaCl2(aq) + __NaOH(aq) __Ba(OH)2 ( ) + __NaCl( )

15 Solubility QQT Inside outside circle

16 Coefficients of a balanced chemical reaction form the mole ratio
Mole to Mole Coefficients of a balanced chemical reaction form the mole ratio

17 How many mole of copper are produced if 2.3 moles of iron are reacted.
Step 1: Write & Balance the Rxn Fe( ) + Cu(NO3)2 ( )  Cu( ) + FeNO3 ( ) Step 2: Set-up problem & solve

18 A 0. 49 mol sample of AgNO3 reacts with excess NaI
A 0.49 mol sample of AgNO3 reacts with excess NaI. How many mol of NaI are needed to react?

19 Potassium sulfate reacts with 5. 70 mols of strontium hydroxide
Potassium sulfate reacts with 5.70 mols of strontium hydroxide. How many mols of precipitate are produced

20 How many moles of CaCl2 will be produced if you start out with 5
How many moles of CaCl2 will be produced if you start out with 5.0 moles of HCl reacting with calcium hydroxide?

21 MOLE DAY CELEBRATIONS MOLE PRESENTATIONS- write the name of your mole on the top of the card, your name underneath set your mole up Mole Vote Mole Feast Mole Dance Party & Karaoke Mole Race

22 Mole Race Teams of 2- choose wisely There are 3 moles hidden within the science wing (E-Hall upstairs and down) You both need pictures with ALL the moles to be in the raffle to win. Send pictures with a witty caption

23 Come up with a list of soluble compounds.
Rally Partner: Person A gives and answer Person B gives an answer continuing until time is called Come up with a list of soluble compounds. Come up with a list of insoluble compounds.
