balanced or unbalanced chemical equations

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 an unbalanced chemical equation?

Back

An unbalanced chemical equation does not have the same number of each type of atom on both sides, meaning that mass is not conserved.

Front

What are reactants in a chemical reaction?

Back

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

Front

What are products in a chemical reaction?

Back

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

Front

What does the law of conservation of mass state?

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

How can you determine if a chemical equation is balanced?

Back

To determine if a chemical equation is balanced, count the number of atoms of each element on both sides of the equation and ensure they are equal.

Front

What is the significance of coefficients in a chemical equation?

Back

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

Front

What is the role of subscripts in a chemical formula?

Back

Subscripts indicate the number of atoms of each element in a molecule; they are not changed when balancing equations.

Front

What is the difference between a chemical equation and a word equation?

Back

A chemical equation uses chemical formulas to represent reactants and products, while a word equation uses words to describe the substances involved.

Front

What does it mean to balance a chemical equation?

Back

Balancing a chemical equation means adjusting the coefficients to ensure that the number of atoms for each element is the same on both sides.
