Types of Chemical Reactions Section 1
Synthesis Reaction
Synthesis = combo of substances to create product that is chemically bonded combo of reactants
Oxidation = addition of oxygen to chemical substance
Formation of Rust: 2Fe +3O (subscript 2) ---→ 2FeO (subscript 3), A + B -→ AB
Wood Burning (combustion)
C(subscript 6)H(subscript 10)O(subscript 5) + 6O(subscript 2) ----> 6CO(subscript 2) + 5H(subscript 2)0
Carbon oxidized to form carbon dioxide, hydrogen oxidized to form water
Cellulose burns in the presence of oxygen to produce carbon dioxide and water vapor
Decomposition Reaction
Hydrogen peroxide: 2H(subscript 2)O(subscript 2) ----> 2H(subscript 2)O + O(subscript 2)
Decomposition = once chemical compound breaks into 2 or more separate compounds/elements
AB ---→ A + B
Combustion Reaction
Similar to synthesis reactions, combo of oxygen & fuel, "fueled" by hydrocarbons, almost always exothermic
hydrocarbon: a compound containing only hydrogen and carbon
Hydrocarbon + O(subscript 2) ---> CO(subscript 2) + H(subscript 2)O
Replacement Reaction
Ions in these compounds: A+, B-, C+, D-
Ab + CD ⇾ AD + CB
Replacement occurs with ions in ionic compounds
Electrolysis (example: Hydrogen Peroxide, seen on bright purple)
Water decomposes to form oxygen and hydrogen gas
