(1 point)
The reactants and products have different types of atoms, but the number of each atom is the same.
The reactants and products have the same number and type of atoms, and the atoms are not recombined.
The reactants and products have different numbers of atoms, but the types of atoms are the same.

The statement that best represents the law of conservation of matter with regard to chemical reactions is:

The reactants and products have the same number and type of atoms, but the atoms may be recombined.

This statement accurately reflects that in a chemical reaction, the total mass and the number of each type of atom remain constant, even though the atoms can be rearranged to form different molecules.
