It allows them to communicate without confusion.

It makes the elements more stable.

It helps them to create new elements.

It changes the properties of the elements.

How do mixtures differ from pure substances?

Mixtures can be separated by physical means.

Mixtures are composed of two or more elements chemically combined.

Mixtures have a fixed composition.

Mixtures are always homogeneous.

A substance made from two or more simpler substances that can be broken down into those simpler substances.

A single element in its pure form.

A substance made from one element that cannot be broken down.

A mixture of elements that cannot be separated.

What does a compound always contain?

One element in a variable proportion.

Which of the following statements is true about hydrogen and oxygen?

Both are solids at room temperature

Both are liquids at room temperature

What is a property of water that differs from hydrogen and oxygen?

Water is a liquid at room temperature

Water is a gas at room temperature

Water is a solid at room temperature

Why can the properties of a mixture vary?

Because the composition of a mixture is not fixed.

Because the composition of a mixture is fixed.

Because the properties of a mixture are more constant than the properties of a substance.

Because mixtures cannot retain any properties of their individual substances.

What can mixtures retain?

Some of the properties of their individual substances.

More properties than their individual substances.

None of the properties of their individual substances.

All the properties of their individual substances.

How can mixtures be classified?

By how well the parts of the mixture are distributed

In a heterogeneous mixture, the parts of the mixture are:

Noticeably different from one another

In a homogeneous mixture, the substances are:

So evenly distributed that it is difficult to distinguish one substance in the mixture from another

Noticeably different from one another

What do a pencil, a quarter, a book, and a cafeteria tray have in common?

They all have a recognizable shape and take up space.
