Answer:
The mass of the reactants is the same as the mass of the products.
Step-by-step explanation:
- According to the law of conservation of mass, the mass of the reactants should be equal to the mass of the products in a chemical equation.
- Balancing chemical equations makes them obey the law of conservation of mass, since it makes the number of atoms of each element equal on both sides of the equation.
- Therefore, for chemical equations to obey the law of conservation of mass, they should be balanced.
