1. 7.5-7.6 Types of Reactions and Combination Reactions By Shannon, Devon, and Lauren

2. Types of Reactions 5 general types 1.Combination- 2.Decomposition- 3.Single Replacement- 4.Double Replacement - 5.Combustion - A chemical change when two substances react to make a single substance A chemical change when a single compound is broken down into two or more simpler products A chemical change when atoms of an element replace atoms of a second element in a compound A chemical change that involves a change of positive ions between two compounds A chemical change when oxygen reacts with another substance producing energy in the form of heat and light

3. Types of Reactions

4. How to Solve Combination Reactions 1.Write the correct formula for the compound using the ionic charges. 2.Balance the equation 3.Write the balance combination reactions formula Mg + O2 2Mg + O2 2MgO

5. Combination Reactions + SO 2 SO 2

6. Guess the Reaction combination combustion decomposition Double replacement Single replacement

7. Ca + S P + O 2 CaS Tetraphosphorus decoxide 4P + 5O 2 P 4 O 10

8. Fun Facts When a metal undergoes a combination reaction with oxygen, a metal oxide is formed Combination reactions are always exothermic.

9. Practice Fe + O 2 Iron (ll) oxide Al (s) + O 2 (g) Homework 2Fe + O 2 2FeO
