1. 6.5 Types of Chemical Reactions Synthesis and Decomposition

2. Types of Chemical Reactions
Synthesis (put together)
Decomposition (break apart)
Single Displacement
Double Displacement

3. Synthesis Reaction
Synthesis Reaction: involves combining two elements (or compounds) into one single compounds.

4. Synthesis Reaction
Example 1: magnesium and nitrogen make magnesium nitride

5. Synthesis Reaction
Example 2:
Zinc + sulfur  zinc sulfide

6. Synthesis Reaction Example 3: sodium + chlorine  sodium chloride
Na Cl  NaCl
Example 4:
ammonia + hydrogen chloride  ammonium chloride

7. Decomposition Reaction
Decomposition Reaction: large compounds are broken into similar compounds or elements. The general formula is the opposite of a synthesis reaction

8. Decomposition Reaction
Example 1:
Water  hydrogen + oxygen
Example 2:
ammonia nitrate  dinitrogen monoxide + water
