Front

What does the arrow in a chemical equation represent?

Back

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

Front

What is the difference between a reactant and a product?

Back

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

Front

What does it mean if a chemical equation is balanced?

Back

A balanced equation has the same number of each type of atom on both sides, indicating that mass is conserved.

Front

What are coefficients in a chemical equation?

Back

Numbers placed before compounds to indicate the number of molecules or moles involved in the reaction.

Front

What are subscripts in a chemical formula?

Back

Numbers that indicate the number of atoms of an element in a molecule, found within the chemical formula.
