1. ❧❧ Decomposition Reactions By: Andrew, CJ, and Kenny

2. Decomposition ❧ Decomposition reaction- A single compound is broken down into two or more products AB=A+B

3. Decomposition (cont.) ❧ Outcomes of decomposition reactions are often difficult to predict. ❧ Most decomposition reactions require energy in the form of heat, light, or electricity

4. Balancing Decomposition Equations It’s simple. You just need to make sure you end up with the same amount of the same atoms that you started with. Example: One of the possibilities of the products of water decomposing is H 2 + O. That is not balanced though. To balance it, you could make the reactant 2H 2 O. 2H 2 O 2H 2 + O 2 Now the equation is balanced!

5. Facts ❧ Decomposition is one of the most common forms of chemical reactions

6. S’more Facts. ❧ When a simple binary compounds breaks down, you know the products will be the elements originally in the compound.

7. The correct answer is C Interactive Questions What is needed for decomposition to occur? __________ in the form of heat, light, or electricity A. Moles B. Atoms C. Energy D. Decomposition

8. Interactive Questions Balance this equation: CaO Ca + O 2 The correct answer is 2CaO 2Ca + O 2

9. HW Question Balance this equation: C 3 H 6 N 6 O 6 Carbon Monoxide, Water, Nitrogen
