Another name for a chemical change is a(n) (1) . Such a change can be represented by means of a written statement called a(n) (2) The symbol for the word "yields" in such a statement is a(n) (3) . Any substance written to the left of this symbol is called a(n) (4) . Any substance written to the right of this symbol is called a(n) (5) . A number written just to the left of a formula is called a(n) (6) .

A chemical change in which two or more substances combine to form a more complex substance is called a(n) (7) reaction. A change in which a substance is broken down into simpler substances is called a(n) (8) reaction. If the change is caused by heat supplied to the reaction, the Greek symbol (9) is often written above the "yields" symbol in the equation.

A chemical change in which a free element replaces and releases another element in a compound is called a(n) (10) reaction. A chemical change in which there is an exchange of ions between two compounds is called a(n) (11) reaction. A solid substance produced by such a reaction in a liquid medium is called a(n) (12) .
