Question

Which statement best represents the law of conservation of matter with regard to chemical reactions?
A. The reactions and products have the same number and type of atoms, but the atoms may be recombined
B. The reactants and products have the same number and type of atoms, and the atoms are not recombined
C. The reactants and products have different types of atoms, but the number of each atom is the same
D. The reactants and products have different numbers of atoms, but the types of atoms are the same

Answer 1

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

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

This statement reflects the principle that in a chemical reaction, atoms are neither created nor destroyed, but they can be rearranged or recombined to form new substances.
