Balancing Chemical Reactions and Types

Front

What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light and heat. Example: 2C3H7OH + 9O2 -> 6CO2 + 8H2O.

What does the Law of Conservation of Mass state?

Back

The Law of Conservation of Mass states that in a closed system, the mass of the reactants must equal the mass of the products; the number of atoms of each element remains the same before and after a reaction.

What is a balanced chemical equation?

Back

A balanced chemical equation has the same number of each type of atom on both sides of the equation, adhering to the Law of Conservation of Mass.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where one compound breaks down into two or more simpler substances. Example: Al(OH)3 -> Al2O3 + H2O.

Front

What is a precipitation reaction?

Back

A precipitation reaction occurs when two solutions are mixed, resulting in the formation of an insoluble solid (precipitate). Example: Mixing solutions A and B to form solid C.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more reactants combine to form a single product. Example: A + B -> AB.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a chemical reaction where one element replaces another in a compound. Example: A + BC -> AC + B.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a chemical reaction where the anions and cations of two different compounds exchange places, forming two new compounds. Example: AB + CD -> AD + CB.

Front

How do you identify a combustion reaction?

Back

A combustion reaction can be identified by the presence of oxygen as a reactant and the production of carbon dioxide and water as products.

Front

What is the significance of balancing chemical equations?

Back

Balancing chemical equations is crucial because it ensures that the Law of Conservation of Mass is upheld, meaning that matter is neither created nor destroyed in a chemical reaction.
