What are the five main types of chemical reactions?
Synthesis, Decomposition, Single Displacement, Double Displacement, Combustion
What occurs in a synthesis reaction?
Two or more reactants combine to form a new larger product.
What is the general pattern for a synthesis reaction?
A + B → AB
Provide an example of a synthesis reaction.
2H2 + O2 → 2H2O
What occurs in a decomposition reaction?
One compound breaks down into two or more smaller compounds or elements.
What is the general pattern for a decomposition reaction?
AB → A + B
Provide an example of a decomposition reaction.
2KClO3 → 2KCl + 3O2
What happens in a single displacement reaction?
One element takes the place of another element in a compound.
What is the general pattern for a single displacement reaction?
AB + C → AC + B
Provide an example of a single displacement reaction involving metals.
2HCl + Mg → MgCl2 + H2
What occurs in a double displacement reaction?
The metal ions of two different compounds exchange places.
What is the general pattern for a double displacement reaction?
AB + CD → AD + CB
Provide an example of a double displacement reaction.
NaOH + HCl → HOH + NaCl
What is a complete combustion reaction?
Reactions involving the burning of hydrocarbons with oxygen, producing carbon dioxide and water.
Blue, hottest flames, most efficient way to burn energy
What is the general pattern for a complete combustion reaction?
CxHy + O2 → CO2 + H2O
Provide an example of a complete combustion reaction.
CH4 + 2O2 → CO2 + 2H2O
What is an incomplete combustion reaction?
Reactions involving the burning of hydrocarbons with limited oxygen, producing carbon, carbon monoxide, carbon dioxide, and water.
Produces yellow, sooty and cooler flames
What is the general pattern for an incomplete combustion reaction?
CxHy + O2 → C(s) + CO + CO2 + H2O
What is corrosion?
The breakdown of metal as a result of chemical reactions with its environment.
What is the Maillard reaction?
A series of chemical reactions between amino acids and sugars in food, leading to browning and flavor development.
