1
Do Now: What is a chemical reaction? What is a reactant? What is a product? Why do substances react with each other?

2
Equation “Sentence” that represents a chemical reaction Reactants Products

3
Word Equation: Magnesium metal reacts with nitrogen gas to produce solid magnesium nitride Magnesium + Nitrogen Magnesium nitride Plus “+” separate substances on each side Yield “” separates reactants from products

4
Chemical Equation: Magnesium metal reacts with nitrogen gas to produce solid magnesium nitride Magnesium + Nitrogen Magnesium nitride Mg (s) + N 2(g) Mg 3 N 2(s)

5
Balanced Chemical Equation: Magnesium metal reacts with nitrogen gas to produce solid magnesium nitride Magnesium + Nitrogen Magnesium nitride Mg (s) + N 2(g) Mg 3 N 2(s) Must satisfy the law of conservation of matter!!! 3

6
Balance equations to satisfy the Law of Conservation of Matter Use coefficients to balance equations Indicate phases (s – l – g – aq)

7
Use your ion sheet to write formulas for the following compounds. Then balance each chemical equations using coefficients. 1. Solid Iron (III) chloride reacts with aqueous sodium hydroxide to form solid iron (III) hydroxide and aqueous sodium chloride 2. Solid Iron (III) oxide reacts with hydrogen gas to produce solid iron and liquid water 3. Sodium bicarbonate, is heated to produce sodium carbonate, carbon dioxide, and water.

8
Yesterday we looked at the following reactions: 3Mg (s) + N 2(g) Mg 3 N 2(s) FeCl 3(s) + 3NaOH (aq) Fe(OH) 3(s) + 3NaCl (aq) Fe 2 O 3(s) +3 H 2(g) 2Fe (s) +3H 2 O (l) 2NaHCO 3(s) Na 2 CO 3(s) + CO 2(g) + H 2 O (l) What is happening in each reaction?

9
5 Basic types of chemical reactions Combination Decomposition Single-Replacement – Double-Replacement – Combustion- – Reactants combine to form 1 product – 1 Reactant produces 2 or more products A +BC -> B + AC AB +CD -> AD + CB C x H y + O 2 -> CO 2 + H 2 O

10
Write a balanced chemical equation for … Copper metal is dropped into a solution of silver nitrate Single Replacement – AB + C CB + A (C is a metal) AB + C AC + B (C is a nonmetal)

11
Write a balanced chemical equation for … Lead II nitrate and sodium iodide Double Replacement – AB + CD AD + CB A change must take place, such as precipitation, formation of pure liquid, or evolution of gas

12
Write a balanced chemical equation for … The combustion of propane, C 3 H 8 (oxygen is required!) Combustion – hydrocarbon + O 2 CO 2 + H 2 O hydrocarbon – a molecular compound containing C and H and possibly O
