Solutions
The properties of matter are determined by the properties of atoms and molecules - Correct Answer
true
Atom - Correct Answer submicroscopic particles that constitute the fundamental building blocks of
ordinary matter
Molecules - Correct Answer Atoms bound together in specific geometrical arrangements to form
molecules
Chemistry - Correct Answer the science that seeks to understand the behavior of matter by studying the
behavior of atoms and molecules
data - Correct Answer descriptions of a characteristic or behavior of nature
Hypothesis - Correct Answer observations often lead to these educated guesses
What makes a hypothesis good - Correct Answer It needs to be falsifiable or able to be proved wrong
law of conservation of mass - Correct Answer "in a chemical reaction, matter is neither created or
destroyed"
Which statement best explains the difference between a theory and a law? - Correct Answer a law
summarizes a series of related observations; a theory gives the underlying reasons for them
, matter - Correct Answer anything that occupies space and has mass (can be classified as solid, liquid, or
gas)
State - Correct Answer an objects physical form
composition - Correct Answer the basic components that make it up
solid matter - Correct Answer atoms or molecules that pack closely together in a fixed location. Can take
the shape of a crystalline
Crystalline - Correct Answer atoms or molecules are in patterns with long-range, repeating order
Amorphous - Correct Answer atoms or molecules do not have any long-range
Liquid matter - Correct Answer atoms or molecules pack around each other as closely as they do in
solids, but are free to move around each other. Have a fixed volume, but not a fixed shape
Gaseous matter - Correct Answer atoms or molecules have a lot of space between them. The gases are
compressible and very free to move around one another
pure substance - Correct Answer made up of only one component, and its composition is invariant
mixture - Correct Answer a substance composed of two or more components in proportions that can
vary from one sample to another
element - Correct Answer substance that cannot be broken down chemical into a simpler form
compound - Correct Answer two or more elements in fixed definite proportions
