Matter Review

Gavin wanted to show his parents a reaction

between an acid and a base as he had done in class

earlier that day. He found baking soda in the

cupboard, but could not find any vinegar. What

could Gavin use for his reaction in place of the

vinegar?

• ammonia

• lemon juice

• tap water

• boiling water

Robert and Daniela are discussing the phases of

water. Robert says that ice, water, and steam are

three different compounds since they have three

different names. Daniela disagrees and says that

all three states are the same compound. Who is

correct and why?

• Robert is correct because the three states of

  water have different physical properties.

• Robert is correct because unique names are

  only given to new compounds that are

  discovered.

• Daniela is correct because all three states of

  water have the same physical properties.

• Daniela is correct because all three states are

  made of the same compound with the same

  ratio of hydrogen to oxygen.

Which of the following is a property of

elements?

• Elements have their own individual

  characteristic properties.

• Elements have at least two different types of

  atoms.

• Elements have the ability to change into a

  different element.

• Elements are can be separated from one

  another.

Compounds are made up of different kinds of

atoms that are chemically combined. What do

compounds have in common?

• The have the same color.

• The have the same melting point.

• They can be broken down into simpler

  substances.

• They cannot combine with one another to

  form more complex substances.

The state of matter is an example of a physical

property. Why is the state of matter considered a

physical property even though a substance may

change between a solid, liquid, and gas?

• The property can be easily observed.

• The chemical nature of the substance does

  not change.

• The state of matter depends on the amount

  of substance present.

• Solids, liquids, and gases have different

  chemical compositions from one another.

A characteristic property is one that is remains the same regardless of the amount of matter that is present.

Which of the following is a characteristic property of matter?

• density

• mass

• volume

• weight

As Jose mixed two substances in a test tube, he noticed that the test tube became warm. He also noticed an odor coming from the test tube. Based on Jose’s observations, what was most likely occurring inside the test tube?

• the substances were melting

• a physical change

• new substances were being formed

• changes in physical properties

Which of the following is most likely evidence of

a chemical change?

• An object gets smaller.

The process of passing an electric current through water is known as electrolysis. During electrolysis, the electric current decomposes water into hydrogen and oxygen gases. Why is the electrolysis of water an example of a chemical change?

• An electric current is used.

• New substances are produced.

• Water undergoes a change in state.

• The composition of the original substance

  remains unchanged.
