Respuesta :
The mass of products in a chemical change remains the same mass it was before the transition.
Answer:
Matter cannot be created nor destroyed in the events of a chemical reaction.
Explanation:
Mass and matter only change forms, aka, it can only be recycled and ultimately will still exist no matter how the parts are rearranged. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted.
