Study Notes
Identifying Reactions
- Reactions can be classified as synthesis, decomposition, single displacement, double displacement, complete hydrocarbon combustion, or combustion of an element.
- Synthesis reactions combine two reactants to form a single product.
- Decomposition reactions break down a single reactant into two or more products.
- Single displacement reactions involve one element replacing another in a compound.
- Double displacement reactions involve the exchange of ions between two reactants.
- Complete hydrocarbon combustion reactions occur when a hydrocarbon reacts with oxygen, producing carbon dioxide, water, and energy.
- Combustion of an element reactions involve an element reacting with oxygen to produce an oxide and energy.
Balancing Chemical Equations
- Balancing chemical equations ensures that the number of atoms of each element on the reactant side equals the number of atoms of that element on the product side.
- This follows the law of conservation of mass, which states that matter cannot be created or destroyed.
Example Reactions
- Iron reacting with oxygen to form iron oxide is an example of a synthesis reaction.
- Iron sulfide reacting with hydrochloric acid to produce iron chloride and hydrogen sulfide is an example of a single displacement reaction.
- Silver nitrate reacting with hydrochloric acid to produce silver chloride and nitric acid is an example of a double displacement reaction.
- Aluminum chloride decomposing into aluminum and chlorine is an example of a decomposition reaction.
- Aluminum reacting with sulfuric acid to produce aluminum sulfate and hydrogen is an example of a single displacement reaction.
- Potassium chlorate decomposing into potassium chloride and oxygen is an example of a decomposition reaction.
- Propane reacting with oxygen to produce carbon dioxide, water, and energy is an example of a complete hydrocarbon combustion reaction.
- Hydrogen gas reacting with oxygen gas to produce water and energy is an example of a combustion reaction.
