8 Synthesis (Combination) Reactions
Exothermic Describes a process that releases energy to the surroundings, most commonly in the form of heat and/or light

9 Decomposition Reactions
A single compound breaks apart, or decomposes, into two or more chemical species A + B

10 Decomposition Reactions
Endothermic Describes a process that absorbs energy from the surroundings, most commonly in the form of heat and/or light

26 Single Replacement Reactions
A reaction between a compound and an element in which the element replaces an element of the same type in the compound, creating a different compound and a different element A + B C metals A + B C non-metals

27 Single Replacement Reactions
A reaction between a compound and an element in which the element replaces an element of the same type in the compound, creating a different compound and a different element A + B C cations A + B C non-metals

28 Single Replacement Reactions
A reaction between a compound and an element in which the element replaces an element of the same type in the compound, creating a different compound and a different element A + B C cations A + B C anions

29 Single Replacement Reactions
A reaction between a compound and an element in which the element replaces an element of the same type in the compound, creating a different compound and a different element A + B C cations A + H C H2 metal

30 Single Replacement Reactions
A reaction between a compound and an element in which the element replaces an element of the same type in the compound, creating a different compound and a different element A + B C cations A + H C H2 cation cation

31 Single Replacement Reactions
In single-replacement reactions, like replaces like – metals replace metals and hydrogen, non-metals replace non- metals

32 Double Replacement Reactions
