When two substances react chemically to produce a new substance, what is TRUE of the mass of the two substances compared to the mass of the new substance?

Respuesta :

Answer:

They have the same mass

Step-by-step explanation:

According to the Law of conservation of mass in a chemical reaction, mass can neither be gained or lost.

Therefore, the mass of the reactants will be equivalent to the mass of the product. Conservation of mass is ensured in a chemical reaction by making the chemical equation balanced.

Therefore, in this case, the mass of the the two substances will be equal to the mass of the new substance.
