  1. Warm-UpMay 20, 2013 • Write down the date and objective. • Objective: SWBAT review Unit 4 material by competing in Who Wants To Be a Chemist? • Complete the following questions for your warm-up: • What is the electron configuration for Zn (zinc)? • What is the noble gas configuration for Sn (tin)? • Describe the three types of chemical bonds.

  2. Objective & Agenda • Objective: SWBAT review Unit 4 material by competing in Who Wants To Be a Chemist? Agenda • Every Monday Matters • Review • Practice Problems • Types of Reaction Puzzle • Who Wants To Be a Chemist? • Final Exam Review • Quiz • Optional Homework

  3. Homework Review

  4. Short Answer 1 1. Atomic size is one of many trends of the periodic table. • Describe one reason atomic size may vary among the elements of the periodic table. • List the correct order of aluminum, magnesium, phosphorus, silicon, sodium, and sulfur, based on decreasing atomic size.

  5. Short Answer 2 • You are explaining the rules of nomenclature to your non-chemistry studying friend. You tell her that CCl4 is called carbon tetrachloride. She says, “Oh, then SnCl4 must be tin tetrachloride.” Is your friend right or wrong? Convince your friend of your opinion.

  6. Unit 7 Tracking

  7. Every Monday Matters • Give a Hug

  8. FACTS • Stimulation by touch is absolutely necessary for physical and emotional well-being • Touch is used to relieve pain, depression, anxiety; to enhance a child’s development and IQ; and to nurture premature babies. • Hugging strengthens the immune system, reduces stress, assists sleep, lowers blood pressure, and is an antidote to depression. • Hugging bolsters a patient’s will to live, dispels loneliness, eases fear, opens doors to buried feelings, builds self-esteem, and imparts feelings of belonging. • Hugging offers a wholesome alternative to promiscuity, alcohol, and drugs. • People need 4 hugs a day for survival, 8 for maintenance and 12 for growth.

  9. Take ACTION Today • Hug the people you care about today. Hug them in the morning, hug them to say hello, hug them because they bring you happiness, hug them to say good-bye, hug them to say “I love you,” hug them to show compassion, hug them if they are sad, hug them if they are hurting, hug them because they did something incredible, or hug them just because. • Hug a total stranger or someone you don’t know all that well… but ask first. • Challenge yourself and your friends to keep track of how many hugs you gave or received today. • Notice how you feel at the end of your hugging day.

  10. YOU Matter • If everyone hugged 4 people today- the minimum requirement for “survival”- that would add up to 1.2 billion hugs. If everyone gave 12 hugs- the number required for “growth”- the total would be 3.6 billion. So take the time to give 12 hugs today. That hug might be exactly what those 12 people needed.

  11. Reaction Types • Synthesis: A+B  AB • Decomposition: AB  A + B • Single Replacement: AB + C  AC + B • Double Replacement: AB + CD  AD + CB • Combustion: CxHy + O2  CO2 + H2O

  12. 1)  NaOH + KNO3 NaNO3 + KOH • Double Replacement

  13. 2)  CH4 + 2 O2 CO2 + 2 H2O • Combustion

  14. 3)  2 Fe + 6 NaBr 2 FeBr3 + 6 Na • Single Replacement

  15. 4)  CaSO4 + Mg(OH)2 Ca(OH)2 + MgSO4 • Double Replacement

  16. 5)  Pb + O2 PbO2 • Synthesis

  17. 6)  Na2CO3 Na2O + CO2 • Decomposition

  18. 7) 2Al  +  6HCl    2AlCl3 + 3H2 • Single Replacement

  19. 8) 3H2+ N2 2NH3 • Synthesis

  20. 9) 2H2O     O2 + 2H2 • Decomposition

  21. 10) CH3OH + O2 CO2 + H2O • Combustion

  22. Balancing • Here’s the deal. • Use the test. Don’t try to figure it out yourself.

  23. Balance __P4 + __O2 ---> __P2O5 • 2, 5, 1 • 1, 2, 5 • 1, 5, 2 • 5, 2, 1 • Balance __MnS + __HCl -> __H2S + __MnCl2 • 1, 2, 2, 1 • 1, 2, 1, 2 • 1, 2, 1, 1 • 1, 1, 1, 2 • Balance __SiH4 + __O2 -> __SiO2 + __H2O • 2, 1, 2, 1 • 2, 2, 2, 2 • 1, 2, 1, 2 • 2, 1, 2, 2 • Balance __CO2 + __H2O ---> __C6H12O6 + __O2 • 6, 1, 6, 6 • 1, 1, 6, 6 • 6, 6, 6, 6 • 6, 6, 1, 6

  24. Mole conversions 1 mole of ANYTHING = 6.02 x 1023 particles 1 mole of ANYTHING = 22.4 liters @ STP 1 mole of ANYTHING = molar mass Given number units units Units you want

  25. What is the mass of 2 moles of KBr? • How many moles are in 5.08 gram XeF4?

  26. Molarity- Stoichiometry • Make sure you know how to use the stoich structures. • You will be given a set on the day of the exam.

  27. Mol to Mol 1) 1 C2H4 + 3 O2 2 CO2 + 2 H2O How many moles of ethylene (C2H4) are required to produce 45 moles of carbon dioxide?

  28. Mol to Mass 1) 1 C2H4 + 3 O2 2 CO2 + 2 H2O How many grams of ethylene (C2H4) are required to produce 45 moles of carbon dioxide?

  29. Mass to Mol 1) 1 C2H4 + 3 O2 2 CO2 + 2 H2O How many moles of ethylene (C2H4) are required to produce 45 grams of carbon dioxide?

  30. Mass to Mass 1) 1 C2H4 + 3 O2 2 CO2 + 2 H2O How many grams of ethylene (C2H4) are required to produce 45 grams of carbon dioxide?
