Chemistry Worksheet: Matter #1

1. A mixture (is/is not) a chemical combining of substances.

2. In a compound the (atoms/molecules) are (chemically/physically)combined so that the elements that make up the compound (retaintheir identities and (do/do not) take on a new set of properties.

3. The smallest identifiable unit of a compound is a(n) ___________,which is made up of ____________ which are chemically bonded.

4. True or False: A mixture is always made up of a combination of elements.

5. In a mixture, the substances (lose/retain) their identities.

6. In a mixture the substances involved (can/cannot) be separated by asimple physical process.
