I believe the answer is salt. because it is a compound of two distinct elements that can be broken down without changing the properties of substance.
A pure substance is a substance that are made up of only one type of an atom or one type of a molecule. Pure substances may be further broken down into elements and compounds.
Infraclass: Placentals
Placental mammals are the most diverse group of mammals with about 4000 discovered species.
The location of the negative charges is evenly distributed throughout the entire atom.
J. J. Tomson concluded that atoms are divisible and that the corpuscles are their building blocks.
Atoms are made up of smaller particles.
J. J. Thomson discovered the electron ( the negative charges of the atom) in 1897.
His "plum pudding" model (1904) suggested: the electrons are embedded in the positive charge and evenly distributed throughout the entire atom.
With this model, he abandoned his earlier hypothesis that the atom was composed of immaterial vortices.
Later, Rutherford demonstrate that J.J Thompson's Plum Pudding model was not accurate.

#SPJ4
The kinetic molecular theory of matter states that:
1. Matter is made up of particles that are constantly moving.
2. A change in phase may occur when the energy of the particles is changed.
3. All particles have energy, but the energy varies depending on the temperature the sample of matter is in. This in turn determines whether the substance exists in the solid, liquid, or gaseous state.
Mn+2 is cation and CO3 is anion
hope it help
