General Chemistry Exam 1 Questions
and Answers
Science - correct answer-A method of asking questions and finding answers.
Matter - correct answer-Everything in the universe that has mass or occupies space.
Energy - correct answer-The capacity to transfer heat or do work.
Chemistry - correct answer-The study of composition, structure, and properties of
matter.
Homogenous - correct answer-A mixture that is uniform throughout. (i.e. vinegar)
Heterogenous - correct answer-A mixture that is NOT uniform throughout. (i.e. salad
dressing)
Element - correct answer-A pure substance that can not be broken down.
Compound - correct answer-A substance consisting of two or more elements.
Law of Constant Composition - correct answer-Every sample of a particular compound
always contains the same elements in the same proportions.
Atom - correct answer-The smallest representative particle of an element.
Filtration - correct answer-A way to separate a substance by using a medium to hold
one of the substances back. (i.e. using a sift)
Distillation - correct answer-Vaporizing volatile components and condensing them.
Intensive Properties - correct answer-Properties of matter independent of quantity. (i.e.
color, malleability, melting temperature)
Extensive Properties - correct answer-Properties that characterize how much of the
object is present. (i.e. length, width, mass, volume)
Physical Properties - correct answer-Properties of a pure substance that can be
observed or measured without changing the substance. (i.e. color)
Density - correct answer-The ratio of an object's mass to its volume.
