Chemistry - (correct Answer) - the study of matter and its interactions
Matter - (correct Answer) - anything that has mass and takes up physical space.
Atom - (correct Answer) - the smallest units of matter that retain the properties of that matter.
Mass - (correct Answer) - A measure of the amount of matter that an object contains.
Volume - (correct Answer) - The amount of physical space a substance or object occupies.
pure substance - (correct Answer) - A type of matter with a constant composition.
subatomic particles - (correct Answer) - electron, protons, and neutrons.
Elements - (correct Answer) - atoms of the same type grouped together.
What is the simplest substance? - (correct Answer) - elements
periodic table - (correct Answer) - displays all known element according to similarities between
elements' properties.
What makes up all of the material in the universe? - (correct Answer) - Matter
What's an example of a pure substances? - (correct Answer) - Aluminum
What's a compound? - (correct Answer) - A substance made up of 2 or more different elements joined
together.
What's an example of a compound? - (correct Answer) - H2O, table salt
What is a mixture? - (correct Answer) - A combination of 2 or more pure substances that retains its own
identity & properties.
What are the 2 types of Mixtures? - (correct Answer) - homogeneous and heterogeneous mixtures

What is the difference between homogeneous mixture and a pure substance? - (correct Answer) - They
both are uniformed, but the composition of pure substance is always the same and in homogenous
mixture each sample may vary.
