6.5 Types of Chemical Reactions Synthesis and Decomposition

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

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

Synthesis Reaction Example 1: magnesium and nitrogen make magnesium nitride

Synthesis Reaction Example 2: Zinc + sulfur  zinc sulfide

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

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

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