Which is most likely to occur during a chemical reaction?(1 point) Responses Mass is conserved. Mass is conserved. New atoms are created. New atoms are created. Atoms of the original substance are lost. Atoms of the original substance are lost. The original substance maintains its properties.

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 reactants must equal the total mass of products in a closed system. The other options, such as creating new atoms or losing atoms of the original substance, are not consistent with the principles of chemistry. Additionally, the properties of the original substances typically change during a chemical reaction.
