Balancing Equations and Types of Reactions

Front

What is a Double Replacement 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 the reactant side of a chemical equation?

Back

The left side of a chemical equation, where the starting substances (reactants) are listed before the yields sign.

What is the balanced equation for the reaction of Aluminum and Oxygen?

Back

4Al + 3O₂ → 2Al₂O₃.

Front

What type of reaction always starts with a hydrocarbon and reacts with oxygen?

Back

Combustion reaction, producing carbon dioxide and water.

Front

What is a Synthesis Reaction?

Back

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

Front

What is the Law of Conservation of Mass?

Back

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

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 does the yields sign (→) indicate in a chemical equation?

Back

It indicates the direction of the reaction, showing that reactants are transformed into products.
