Balancing Equations and Types of Reactions Practice

Front

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, indicating that mass is conserved during the reaction.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of 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 decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products. Example: AB → A + B.

Front

What is a single displacement reaction?

Back

A single displacement reaction is a type of reaction where one element replaces another in a compound. Example: A + BC → AC + B.

Front

What is a double displacement reaction?

Back

A double displacement reaction is a type of reaction where the anions and cations of two different compounds exchange places to form two new compounds. Example: AB + CD → AD + CB.

Front

How do you determine the coefficients in a balanced equation?

Back

Coefficients are determined by adjusting the numbers in front of the compounds to ensure that the number of atoms for each element is the same on both sides of the equation.

Front

What are reactants in a chemical reaction?

Back

Reactants are the starting substances in a chemical reaction that undergo change to form products.

Front

What are products in a chemical reaction?

Back

Products are the substances formed as a result of a chemical reaction.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.

Front

What is the significance of the arrow in a chemical equation?

Back

The arrow in a chemical equation indicates the direction of the reaction, showing that reactants are transformed into products.
