5 Chemistry Name: Types of Reactions My action plan to help me improve my learning includes: Review labs, notes, packet and activities. Use the calendar to make sure everything is reviewed. Have a family member or friend quiz me orally. Meet with my teacher in the morning/afterschool for extra help. Use the magic calculator online to check your calculation answers to appropriate labs. Complete and review homework problems by reworking them and NOT just looking at them. Use Objective Checklist throughout unit to assess understanding Period: Ask and answer questions during class. Start studying early! (Not just the night before the test.) Re-read or review all assigned sections from the book. Do online practice quizzes available through class website or through internet. Find a study buddy from Chemistry who understands the material and I can work well with. Use Objective Checklist as a study guide Use this checklist as your personal guide to assess your level of readiness for quizzes and the unit test. Circle the descriptor that best describes how you feel about your mastery of each objective. NOTE: IF IT IS NOT A, YOU PROBABLY ARE NOT READY FOR THE QUIZ/TEST!!!!! = I get it? = I need more practice/review! = I need to get help During Unit Before Test (An asterisk indicates an overarching theme from a past unit!) I feel confident that I?!?! 1. Identify the five types of reactions.?!?! 2. Predict products for any of the five types of reactions from formulas or chemical names. Be able to balance the complete equation.?!?! 3. Using the activity series, predict whether a reaction will occur or not for single replacement reactions from formulas or chemical names or in a lab situation.?!?! 4. Using the solubility chart, predict whether a reaction will occur or not for double replacement reactions from formulas or chemical names or in a lab situation. Check off the study skills you USED to move from? or! to while studying for the test. I have carefully self-assessed my work during this unit and have taken steps to get my questions answered before the quiz/test. Student Signature: Parent Signature: Date: 5

15 Solubility Chart: Combination of cations with anions either produce no precipitate, (i.e. the ions do not combine in solution) or they form a precipitate, leaving less than 1% of the ions in solution. Soluble combinations are labeled (aq); insoluble combinations are labeled (s). Some combinations form gases or undergo complex reactions, these are labeled d, indicating decomposition. Spaces labeled indicate no reference was found. Group I & C2H3O2 - AsO4 3- Br - CO3 2- Cl - CrO4 2- OH - I - NO3 - C2O4 2- O 2- PO4 3- SO4 2- NH4 + (aq) (aq) (aq) (aq) (aq) (aq) (aq) (aq) (aq) (aq) (aq) (aq) (aq) (aq) (aq) Al 3+ (aq) (s) (aq) (aq) (s) (aq) (aq) (s) (s) (aq) d Ba 2+ (aq) (s) (aq) (s) (aq) (s) (aq) (aq) (aq) (s) (aq) (s) (s) d (s) Bi (aq) d (s) d (s) (s) d (s) (s) (aq) d (s) Ca 2+ (aq) (s) (aq) (s) (aq) (aq) (s) (aq) (aq) (s) (s) (s) (aq) d (s) Co 2+ Ni 2+ Cu 2+ (aq) (s) (aq) (s) (aq) (s) (s) (aq) (aq) (s) (s) (s) (aq) (s) (s) Fe 2+ (aq) (s) (aq) (s) (aq) (s) (aq) (aq) (s) (s) (s) (aq) (s) (s) Fe 3+ (s) (s) (aq) (aq) (s) (aq) (aq) (s) (s) (aq) (s) Pb 2+ (aq) (s) (s) (s) (s) (s) (s) (s) (aq) (s) (s) (s) (s) (s) (s) Mg 2+ (aq) d (aq) (s) (aq) (aq) (s) (aq) (aq) (s) (s) (s) (aq) d (aq) Hg 2+ (aq) (s) (s) (s) (aq) (aq) (s) (s) (aq) (s) (s) (s) d (s) Ag + (aq) (s) (s) (s) (s) (s) (s) (s) (aq) (s) (s) (s) (s) (s) (s) Zn 2+ (aq) (s) (aq) (s) (aq) (s) (s) (aq) (aq) (s) (s) (s) (aq) (s) (s) S 2- SO3 2- It is useful to remember that all compounds containing Group I A ions are soluble.

17 PROVE IT! : SINGLE REPLACEMENT REACTIONS Purpose: To practice determining whether or not single replacement reactions will occur based on an activity series, and then proving it in the lab. Procedure: Using your activity series, predict whether or not a reaction will occur for the following combinations. If your prediction is for "no reaction," record NR on the product side. If your prediction is that a reaction will occur, write in the products and balance the equation. (You can assume any copper ions formed have a 2+ charge). 1. Mg + AgNO3 (aq) 2. Cu + Mg(NO3)2 (aq) 3.

Zn + Mg(NO3)2 (aq) Once you are confident in your answers to the above, go back to the lab and PROVE IT! YOU ONLY HAVE ONCE CHANCE TO PROVE IT, SO DOUBLE CHECK YOUR ANSWERS BEFORE GOING INTO THE LAB! No pens/pencils in the lab!!! Place the above numbered reactions into your well plate as follows. Place a large X in the wells that you predict No Reaction will occur. Call your teacher over to prove your predictions 17

18 PROVE IT! : DOUBLE REPLACEMENT REACTIONS Purpose: To practice determining whether or not double replacement reactions will occur based on a solubility chart, and then proving it in the lab. Procedure: Using your solubility chart, predict whether or not a reaction will occur Write each reactant as a formula, and predict whether or not a reaction will occur. If your prediction is for "no reaction," record NR on the product side. If your prediction is that a reaction will occur, write in the products (as formulas) and balance the equation. 1. potassium carbonate + iron (II) sulfate 2. potassium carbonate + lead (II) nitrate 3. potassium carbonate + sodium hydroxide 4. iron (II) sulfate + lead (II) nitrate 5. iron (II) sulfate + sodium hydroxide 6. lead (II) nitrate + sodium hydroxide Once you are confident in your answers to the above, go back to the lab and PROVE IT!
