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

  2. Types of Reactions5 general types • Combination- • Decomposition- • Single Replacement- • Double Replacement - • 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 • Write the correct formula for the compound using the ionic charges. • Balance the equation • Write the balance combination reactions formula Mg + O2 2Mg + O2 2MgO

  5. Combination Reactions + S SO O 2 2

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

  7. Ca + S CaS P + O2 Tetraphosphorusdecoxide P4O10 4P + 5O2

  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 + O2 Iron (ll) oxide 2FeO 2Fe + O2 Homework Al(s) + O2(g)
