The statement is false. The difference between homogeneous and heterogeneous mixtures does not involve whether chemical bonds are formed. In both homogeneous and heterogeneous mixtures, no new chemical bonds are created. Mixtures involve the physical combination of substances, and the components retain their original chemical properties. The key difference between the two types of mixtures lies in the uniformity of distribution:
In a homogeneous mixture, the components are evenly distributed at the molecular or atomic level, creating a uniform appearance throughout the mixture (like a solution).
In a heterogeneous mixture, the components are not evenly distributed, and they can be seen as distinct phases or regions within the mixture, giving it a non-uniform appearance.
Chemical bonds involve the sharing or transfer of electrons between atoms to form compounds, which is a different concept from mixtures.
