Which of the following observations likely describes a
physical change?
A solid was exposed to heat and became a liquid.
A piece of metal was added to a liquid and bubbles
formed on the surface of the metal.
A white solid was exposed to ultraviolet light and
turned brown.
Two clear liquids were mixed together, and a yellow
solid formed.
A student places a beaker of liquid water on a hot plate. After a few minutes, bubbles form in the water. The student tests the bubbles and determines that they contain gaseous water. Is the formation of bubbles by the heating of water a physical change or a chemical change?
The change is chemical because a new substance was
formed.
The change is chemical because formation of a gas
indicates a chemical change.
The change is physical because no new substances
were formed.
The change is physical because the physical properties
of the substance changed.
Which of the following includes an example of a chemical
property of an element?
Aluminum is solid at room temperature.
Sulfur is not shiny and is not malleable.
Sodium reacts with other elements.
Silicon is shiny and is a poor conductor of electricity.
Which of the following is an example of a chemical
change?
Water freezes.
Wood is cut in half.
Bread is baked in an oven.
A copper wire is bent.
Which of these is a physical change?
Wood burning.
An ice wedge shattering a slab of shale.
Sulfuric acid corroding limestone.
Acid rain damaging granite.
A student measures the volume of a substance to be 3.25
ml. Can the student determine the identity of the
substance from this measurement?
No, because volume is an intensive property.
No, because volume is an extensive property.
Yes, because volume is an intensive property.
Yes, because volume is an extensive property
The table below lists some properties of a sample of lauric acid.
Which of these is a intensive property?
Volume
Mass
Boiling Point
Number of moles
You have measured the length and density of a pure metal
object in your chemistry lab. You will be able to identify the
metal the object is made of because
length is an intensive property.
length is an extensive property.
density is an intensive property.
density is an extensive property.
The value of an extensive property is directly related to
a substance’s
temperature.
amount.
density.
elements.
Which of the following pairs of properties includes one
extensive property and one intensive property?
density, mass
length, radius
mass, volume
malleability, hardness
Which of the following correctly describes the particles in
a solid compared to the particles in a liquid?
Particles in a solid are farther apart than particles in a
liquid.
Particles in a liquid are much farther apart than
particles in a solid.
Particles in a solid do not move at all, and particles in a
liquid slide past one another.
Particles in a solid vibrate in place and particles in a
liquid slide past one another.
Which observations were likely made of a gas?
This substance filled only the bottom half of a
container.
The volume of this substance did not change when
pressure was applied.
When this substance was transferred from a smaller
container to a larger container, its volume increased.
When this substance was moved from one container to
another, its shape stayed the same.
Which of the following correctly describes what happens
when an inflated balloon is compressed?
When the gas is compressed, its particles get smaller.
When the gas is compressed, its particles get closer
together.
When the gas is compressed, its particles get larger.
When the gas is compressed, its particles get farther
apart.
Which of the following best explains why CO2 gas is easily
compressible but solid CO2 is incompressible?
The molecules of CO2 gas are much closer together
than the molecules in dry ice.
The molecules of solid CO2 are much closer together
than the molecules of CO2 gas.
The molecules of CO2 gas are much smaller than the
molecules of solid CO2.
The molecules of CO2 gas attract one another, while
the molecules of the solid CO2 repel one another.
Which of the following correctly identifies the states of
matter depicted below?
1-liquid, 2-solid, 3-gas
1-gas, 2-solid, 3-liquid
1-solid, 2-liquid, 3-gas
Not enough information given
A student is given a sample of matter to classify. The
sample is uniform in color and texture. Based on this
information, the student can determine which of the
following?
The sample is an element.
The sample can be an element or a compound.
The sample is a homogeneous mixture.
The sample can be a homogeneous mixture or a
pure substance.
A new material was produced in a laboratory by bonding
atoms of different elements together in a unique
arrangement. Other laboratories were able to reproduce
these results, producing the same material with the same
elements in the same arrangement. What type of matter
was produced?
element
compound
homogeneous mixture
heterogeneous mixture
Vinegar is classified as a mixture. What does this tell
you about vinegar?
Vinegar is made of atoms of one type of element.
Vinegar is made of atoms of different elements
chemically bonded together.
Vinegar has a composition that is the same
wherever it is found.
Vinegar contains two or more pure substances mixed
together.
A scientist filters a sample of river water. The data from this
process are listed below. Which of the following is a correct
description of the sample?
It is a pure substance because solid particles cannot
pass through the filter paper.
It is a pure substance because the river water is
composed of only free elements.
It is a mixture because dissolved ions in the water pass
through the filter paper.
It is a mixture because solid particles are separated
from the river water.
Which type of matter is composed of two or more
elements that are chemically combined in a fixed
proportion?
Homogenous mixture.
Heterogenous mixture.
Compound.
