What is the definition of a scientific theory? - Answer a model that explains the underlying
reasons for observations and laws
What term best describes a brief statement that summarizes many past observations and
predicts new ones? - Answer scientific law
Which of the following is an example of a scientific law? - Answer In a chemical reaction,
matter is neither created nor destroyed.
Which of the following would be considered a theory? - Answer Helium balloons float because
helium is less dense than air.
The key to success in chemistry is: - Answer all of the above
A plastic block has dimensions of 2.2 cm x 3.0 cm x 1.5 cm and a mass of 12.4 grams. Will the
block float in water and why? - Answer No, because the density of the block is 1.3 g/mL which
is greater than the density of water.

Suppose a boat engine leaks 938 mL of oil into a lake. The mass of this spilled oil is 823 g. The oil
will not mix with the lake water. Which statement is true? - Answer The oil will float because
its density of 0.877 g/mL is less than the density of water.
Which state of matter has indefinite shape and is compressible? - Answer gas
A solution is an example of a (an): - Answer homogeneous mixture
Which of the following is NOT an example of a physical property? - Answer Water can form
hydrogen and oxygen under electrolysis conditions.
Which of the following is a homogeneous mixture? - Answer stainless steel
When methane is burned with oxygen the products are carbon dioxide and water. If you
produce 36 grams of water and 44 grams of carbon dioxide from 16 grams of methane, how
many grams of oxygen were needed for the reaction? - Answer 64
Which of the following statements about matter is FALSE? - Answer Matter is smooth and
