Types Of Chemical Reactions Flashcards
What is a synthesis reaction?
A reaction where two reactants combine to make a larger or complex reaction.
A+B -) AB
What is a decomposition reaction?
A reaction where a large or more complex molecule breaks down to form two or more simpler products.
AB -) A+B
What is a simple displacement reaction?
A reaction where an element displaces another element in a compound producing a new compound and a new element.
A+BC -) AC+B
What is a double displacement reaction?
A reaction where elements in different compounds displace each other or exchange places producing two or new compounds.
AB+CD -) AD+CB
What is combustion?
A chemical reaction where a fuel “burns” quickly with oxygens.
What are examples of fuels for combustion?
Hydrogen
Phosphorus
Hydrocarbons (like propane)
What are the two types of combustion?
Incomplete and complete combustion
What is complete combustion?
A reaction of hydrocarbons that uses all the available fuel and produces only carbon dioxide, water, and energy; occurs when the oxygen supply is large.
What is the word equation for complete combustion?
Hydrocarbon + Oxygen -) Carbon Dioxide + Water + Energy
What is incomplete combustion?
A reaction of hydrocarbons that may produce carbon monoxide, carbon dioxide, water, and energy; it occurs when the oxygen is limited.
What is the word equation for incomplete combustion?
Hydrocarbons + Oxygen -) Carbon Dioxide + Water + Carbon Monoxide + Carbon + Energy
What is combustion of hydrogen?
When hydrogen reacts (burns) with oxygen to form water
How can combustion of hydrogen be reversed?
Through a process called Electrolysis.
What is corrosion?
The breakdown of a metal resulting from reactions with chemicals in its environment, usually air and water.
What are the main culprits of rusting?
Oxygen and Water
