Which best explains why it is important to conserve energy resources?

• They are all renewable.

• They are all nonrenewable.

• As the use of fossil fuels increases, it becomes more difficult to find alternative energy resources.

• As the most readily available resources run out, it becomes more difficult to obtain additional resources from the earth.

When elements chemically combine, which best describes the resulting compound?

• It has different ratios of atoms.

• It has different types of matter.

• It has the same properties as the uncombined elements.

• It has different properties from the uncombined elements.
