Question

Which is most likely to occur during a chemical reaction? Responses: Atoms of the original substance are lost. Atoms of the original substance are lost. Mass is conserved. Mass is conserved. The original substance maintains its properties. The original substance maintains its properties. New atoms are created.

Answer 1

The most likely occurrence during a chemical reaction is that mass is conserved. According to the law of conservation of mass, the total mass of the reactants is equal to the total mass of the products in a chemical reaction, meaning that atoms are neither lost nor created, and the original substance does not maintain its properties after the reaction.
