  1. Benchmark 1 Review Day 09.27 & 09.28 2012 Chemistry Ms. Boon

  2. Catalyst • Earlier this week we watched a video showing solid sodium combining with water to form sodium hydroxide and hydrogen gas. • Balance the chemical equation: • ___Na (s) + __H2O (l) → __NaOH (aq) + __H2 (g) • 2 Na (s) + 2 H2O (l) → 2 NaOH(aq) + H2 (g) • How many atoms make up the compound NaOH? • 3 – Na, O, H • What is the molar mass of sodium hydroxide (NaOH)? • Na = 23, O = 16, H = 1 … 23+16+1= 40 g/mol • HW Due Today: p. 271 #1-3 & p. 298 #1, 2, 3, 5, 6, 7

  3. Objectives • I can balance chemical equations. • I can make calculations involving moles, molar mass, and number of particles.

  4. Agenda • Catalyst (10) • Homework Review (1o) • Benchmark Review Stations (70-80) • Mole Quiz #1 (20)

  5. Homework Review p. 271 #1-3 p. 298 #1, 2, 3, 5, 6, 7 • __C2H2 + __O2→ __CO2 + __H2O 2 C2H2+ 5 O2→ 4 CO2+ 2 H2O • __Fe(OH)2 + __H2O2 → __Fe(OH)3 2 Fe(OH)2+ H2O2→ 2 Fe(OH)3 • __FeS2 + __Cl2 → __FeCl3 + __S2Cl2 2 FeS2+ 5 Cl2→ 2 FeCl3+ 2 S2Cl2

  6. Homework Review p. 271 #1-3 p. 298 #1, 2, 3, 5, 6, 7 • D • B • A • C • A • C

  7. Agenda • Catalyst (10) • Homework Review (1o) • Benchmark Review Stations (70-80) • Mole Quiz #1 (20)

  8. Benchmark Review Stations • Each table is a station. (15-20 min. per station) • Show your work on your own sheet of paper. • 8 people or less per station. • Station 1: Atoms, Ions, Isotopes Mystery Bags • Station 2: The Mole Review Exercises • Station 3: Balancing Chemical Reactions • Station 4: Vocabulary Posters

  9. The Mole #1 Quiz: Instructions • The quiz has 3 parts: • Part 1: Avogadro’s Number • Part 2: Molar Mass • Part 3: Mole and Mass Conversions • Do not answer every question!!! • Choose 5 questions per section. • Do not write on the quiz. • Show your work and your answers on your own paper. • Label your answers carefully so I know what questions you answered.
