What is the difference between a compound and a mixture?

• A compound is made of two or more elements chemically bonded together, while a mixture consists of two or more substances that are physically combined but not chemically bonded.

• A compound consists of two or more substances that are physically combined, while a mixture is made of elements chemically bonded together.

• A compound can be separated into its components by chemical means, while a mixture cannot be separated.

Can compounds be separated into their elements?

• Yes, compounds can be separated into their elements through chemical reactions.

• No, compounds cannot be separated into their elements under any circumstances.

• Compounds can only be separated into their elements through physical means.

What is a homogeneous mixture?

• A mixture that has a uniform composition throughout, such as saltwater.
