Answer the following question given this paragraph: Elements and Compounds Any sample of matter that has the same physical and chemical properties throughout the sample is called a substance. There are two types of substances. A substance that cannot be broken down into chemically simpler components is an element. Aluminum, which is used in soda cans, is an element.

In contrast, scientists have identified tens of millions of different compounds to date. Q: Any sample of matter that has the same physical and chemical properties throughout the sample is called what? Choices: - element - molecule - type - substance A:
substance
