CHEMISTRY 101 EXAM 1 REVIEW QUESTIONS
WITH CORRECT ANSWERS
Matter - CORRECT ANSWER -Anything that occupies space and has mass.
Atoms - CORRECT ANSWER -
The submicroscopic particles that constitute the fundamental building blocks of ordinary matter.
Molecules - CORRECT ANSWER -
Combinations of atoms bound together in specific arrangements.
Scientific Method - CORRECT ANSWER -
Process for understanding nature by observations and conducting experiments.
Hypothesis - CORRECT ANSWER -A tentative interpretation or explanation of the observations.
Experiment - CORRECT ANSWER -
A set of highly controlled procedures designed to test whether an idea about nature is valid.
Scientific Law - CORRECT ANSWER -A brief statement that describes the behavior of nature.
Theory - CORRECT ANSWER -A general explanation for behavior and characteristics of nature.
Solid Matter - CORRECT ANSWER -
State where atoms or molecules are packed close to each other in fixed locations.
Particle motion is vibrational only.
, Crystalline Solid - CORRECT ANSWER -
Atoms or molecules in a pattern with long range, repeating order.
Ex. table salt and diamond
Amorphous Solid - CORRECT ANSWER -atoms or molecules have no long range order.
Ex. glass and plastic
Liquid Matter - CORRECT ANSWER -
State where atoms or molecules are packed closely together, but are free to move relative to ea
ch other.
Have a fixed volume but no fixed shape.
Gaseous Matter - CORRECT ANSWER -
State where atoms or molecules have a lot of space between them. They are free to move relati
ve to each other.
Are highly compressible.
Pure Substance - CORRECT ANSWER -Made of only one component. Composition is invariant.
Mixture - CORRECT ANSWER -
Two or more components. Proportions can vary from one sample to another.
Element - CORRECT ANSWER -
Substances that cannot be chemically broken down into simpler substances.
Compounds - CORRECT ANSWER -
Substances that are composed of two or more elements in fixed, definite proportions. Can be br
oken down with chemical reactions.
