Types of Chemical Reactions We will study 4 types

Synthesis (or combination) Reactions Involve the combination of smaller atoms and/or molecules into larger molecules. Example: hydrogen + oxygen  water

Synthesis (or combination) Reactions Involve the combination of smaller atoms and/or molecules into larger molecules. Example: hydrogen + oxygen  water

Decomposition Reactions Involve the splitting of larger molecules into smaller atoms and/or molecules. Example: water  hydrogen + oxygen

Decomposition Reactions Involve the splitting of larger molecules into smaller atoms and/or molecules. Example: water  hydrogen + oxygen

Single Displacement Reactions Chemical changes that involve an element and a compound as reactants. One element displaces or replaces another element from a compound.

Single Displacement Reactions Example: magnesium + silver nitrate  silver + magnesium nitrate

Double Displacement Reactions Elements in different compounds displace each other.

Double Displacement Reactions Example: lead(II) nitrate + potassium iodide  lead(II) iodide + potassium nitrate
