Question

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

Explanation:

In a chemical reaction, atoms are rearranged to form products. The name of each element remains the same as elements are conserved. The nuclei are not affected in a chemical reaction (nuclear reactions are different). According to the law of conservation of mass, the total mass of reactants equals the total mass of products. So the aspect that changes is the arrangement of atoms.

Answer:

arrangement of the atoms
