Balancing Equations and Types of Reactions

Front

What is a Double Displacement Reaction?

Back

A chemical reaction where two compounds exchange ions or bonds to form two new compounds. Example: AB + CD → AD + CB.

Front

What is a Combustion Reaction?

Back

A chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat. Example: CxHy + O2 → CO2 + H2O.

Front

How do you balance a chemical equation?

Back

By adjusting the coefficients of the reactants and products to ensure the same number of each type of atom on both sides of the equation.

Front

What are the coefficients used to balance the equation: 2Ag2O → __ Ag + __ O2?

Back

4, 1.

Front

What is a Synthesis Reaction?

Back

A reaction where two or more simple substances combine to form a more complex product. Example: A + B → AB.

Front

What is a Decomposition Reaction?

Back

A reaction where a single compound breaks down into two or more simpler products. Example: AB → A + B.

Front

What is a Single Replacement Reaction?

Back

A reaction where one element replaces another in a compound. Example: A + BC → AC + B.

Front

What is a chemical equation?

Back

A symbolic representation of a chemical reaction, showing the reactants and products with their respective quantities.

Front

What is the Law of Conservation of Mass?

Back

In a chemical reaction, mass is neither created nor destroyed; the total mass of reactants equals the total mass of products.

Front

What is the role of coefficients in a chemical equation?

Back

Coefficients indicate the number of molecules or moles of a substance involved in the reaction.
