While creating a piece of art work, a student becomes curious about the ink he is using to create his art. He wonders if the in
is a pure substance or a mixture. The ink appears to be uniform throughout, but separates when a chromatography experimer
is performed on it, leaving multiple marks of different colors along the chromatography paper.
Using his observations of the properties of the ink, the student can classify it as a
heterogeneous mixture.

The INCORRECT alternative is: D) All living and nonliving things consist of matter, which is anything that occupies space and has mass. Mass is the amount of matter in any object, which does not change. Weight, the force of gravity acting on matter, does change. When objects are farther from Earth, the pull of gravity is strong; this is why the weight of an astronaut is close to zero in outer space. 5. Structure of Atoms: each element is made up of atoms, the smallest units of matter that retain the properties and characteristics of the element. Is CORRECT to affirm that: B) One subatomic particle composed of individual atoms. Only three types of subatomic particles are important for understanding the chemical reactions in the human body: protons, neutrons, and electrons. The dense central core of an atom is its nucleus. Within the nucleus are positively charged neutrons (p+) and uncharged (neutral) protons…arrow_forward
