  1. 1/30/2012 Standards: 3My Website - www.MrWiggerSci.com/chem Objectives: 1. be able to recognize 6.02 x 1023 = mole = Avogadro's Number 2. be able to convert from representative particles<----> moles DO NOW: 1. Write 1 paragraph (5-10 sentences) on a separate sheet of paper, not on your whiteboard. (5 pts) MISC (turn in to basket when completed) REFLECTION Subject: What do you plan to do different this semester than you did last semester? This should be something(s) that will allow you to improve your grade and/or perform well on the CST test. HOMEWORK: 1. Ch 11.1, PP's p. 311     1-3 AND App A, p. 876, Ch 11.1     1-4 (5 pts) Std 3 ========================================================== STAMPS: Journal - none 1. SN Ch 11.1 p. 137-140 (5 pts) Std 3 Notebook - To Keep All of MISC Stamp sec - 3 prints Print a new Notebook Total Sheet

  2. Representative particles can be atoms or molecules (aka formula units) Page 310

  3. 1 mol = 6.02 x 1023 1 mol Na atoms = 6.02 x 1023 Na atoms 1 mol NaCl = 6.02 x 1023 NaCl molecules 1 doz = 12 1 doz eggs = 12 eggs 1 gross = 144 1 gross eggs = 144 eggs Representative Particles: molecules - example NaCl atoms - example Ti or N or Al

  4. A mole is just a number: 6.02 x 1023 ·If 1 mol Al atoms = 6.02 x 1023 Al atoms, How many atoms are in 3.5 mol of Al ?

  5. If you have 4.6 mol B, how many B atoms?

  6. 1/31/2012 Standards: 3 (Stoichiometry) Objectives: Via Video at home a. be able to convert from moles <----> representative particles b. be able to divide or multiply powers of 10 and change to Scientific Notation (pen method) Video In Class Students will have opportunity to change their lives for the better! DO NOW: 1. Answer questions on handout "Gifted Hands..." as you are watching the video. (5 pts) Std MISC HOMEWORK: 1. Mole <---> representative particle Conversion Practice - Tutorial 1st 5 questions only (3 pts) Std 3 2. Ch 11.1, PP's, p. 312     4 (a-d) (2 pts) Std 3 ========================================================== STAMPS: Journal 1/30 1. Stamp: Ch 11.1, PP's p. 311     1-3 (5 pts total for both) Std 3 App A, p. 876, Ch 11.1     1-4 1. Given 5.5 mole CoCl2 how many formula units are there? 2. Given 4.4 x 1025 atoms Cl, how many moles are there? Give this lesson on video! Show Gifted Hands w Cuba Gooding, Jr. What makes learning fun and enjoyable? How do you make you mark in the world. When you are dead - how many will come to your funeral and why? I'll tell you - those who you have had a positive influence on. How will you be remembered. Pray like there is no tomorrow and live as if you will survive to be 100 yrs old (Ben Franklin)

  7.
