Chemical Reactions: Vocab and HW Questions Evidences of a Chemical Reaction Notes Monday, December 12, 2011 (B) Tuesday, December 13, 2011 (A) Page 69 Warm Up: Identify each container as a beaker full of elements, compounds, heterogeneous mixture or homogeneous mixture. Page 70 Homework: Review notes for assessment next class Pure sub. V. mixtures and chemical reaction evidences Monday, December 12, 2011 (B) Tuesday, December 13, 2011 (A) 3. Formation of a Gas – a)Hydrogen Peroxide + yeast O 2 - A glowing splint will re-light when added to test tube b)Baking Soda + vinegar CO 2 - A burning splint will go out when added to test tube c) Zinc + hydrochloric acid H 2 - The zinc disappears and you see bubbles (gas) 1.Color Change – bleach added to water with food coloring will take away the color 2. Formation of a Precipitate – When you add ammonia to a mixture of water and alum, you see a white precipitate 4. Temperature Change – Endothermic – Energy taken in – gets colder -ice pack Exothermic – Energy given off – gets hotter - firecrackers Evidences of a Chemical Reaction (Draw in pictures of the demos as we do them)

Balance Equations handout (both sides) Law of Conservation of Matter and Ziplock Bag Chemistry Lab Wednesday, December 14, 2011 (B) Thursday, December 15, 2011 (A) Page 73 Warm Up: Page 74 Homework: Balance Equations handout (both sides) Wednesday, December 14, 2011 (B) Thursday, December 15, 2011 (A) 1. What type of evidence for chemical reactions do firecrackers have? Give a general and a specific answer. 2. Name and provide an example of the 4 evidences of chemical reactions. There is no observable change in the quantity of matter during a chemical reaction or a physical change. In other words, matter cannot be created nor destroyed. It is just converted from one form to another Show formulas for substances in the reaction Left of arrow = reactants Right of arrow = products Arrow = yields or produces Reactants must equal products!!

Balancing Equations Example 1 Subscripts = small # – Indicate # of atoms of elements Coeffients = large # – Indicate # of molecules of compounds Na + Cl NaCl Na =1Na = 1Cl = 1 Super Easy and Balanced!!

Balancing Equations Example 2 Subscripts = small # – Indicate # of atoms of elements Coeffients = large # – Indicate # of molecules of compounds H 2 + O 2 H 2 O H=2 H = 2 O=2 O = 1 2H 2 + O 2 2H 2 O H=4 H = 4 O=2 O = 2 Balanced!
