Categorizing and Balancing Chemical Reactions

Front

What is a chemical reaction?

Back

A process in which substances (reactants) are transformed into different substances (products) through the breaking and forming of chemical bonds.

Front

What does it mean to balance a chemical equation?

Back

To ensure that the number of atoms of each element is the same on both sides of the equation, reflecting the conservation of mass.

Front

What is the general form of a synthesis reaction?

Back

A + B → AB, where two or more reactants combine to form a single product.

Front

What is a decomposition reaction?

Back

A reaction where a single compound breaks down into two or more simpler products, represented as AB → A + B.

Front

What is a single replacement reaction?

Back

A reaction where one element replaces another in a compound, represented as A + BC → AC + B.

Front

What is a double replacement reaction?

Back

A reaction where the anions and cations of two different compounds exchange places, represented as AB + CD → AD + CB.

Front

How do you identify a combustion reaction?

Back

A reaction that involves oxygen and produces heat and light, typically resulting in carbon dioxide and water as products.

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 are used to indicate the number of molecules or moles of a substance involved in a reaction, helping to balance the equation.

Front

What is the difference between reactants and products?

Back

Reactants are the starting substances in a chemical reaction, while products are the substances formed as a result of the reaction.
