Question

In a chemical reaction, which aspect of the reactants changes?(1 point) Responses total mass total mass name of each element name of each element arrangement of the atoms arrangement of the atoms nuclei

Answer 1

In a chemical reaction, the aspect of the reactants that changes is the **arrangement of the atoms**. While the total mass remains constant (according to the law of conservation of mass), and the names of the elements do not change, what occurs during the reaction is a reorganization of the atoms into new structures, resulting in the formation of products with new properties.
