Jelaskan bukti bahwa senyawa memiliki sifat berbeda dengan atom penyusunnya?

Of course, compounds have entirely different chemical properties from the elements that make them up. Remember that compounds are the results of chemical changes. These chemical changes involve chemical reactions between two or more substances. During these changes, atoms are rearranged to form new products completely different from the starting ones. However, the total mass of the substances before the reaction and substances after the reaction still stay the same.

Remember too that stuff combined chemically cannot be separated physically. They need to be separated chemically and under certain conditions.
