reactant product
This passage describes a chemical reaction. Read the passage. Then, follow the instructions below.
Candles can be made from beeswax, the substance bees use to build honeycombs. As a beeswax candle's string, or wick, burns, the wax melts and rises up the string. The wax combines with oxygen in the air, forming carbon dioxide and water. This process releases energy in the form of light and heat.
A chemical change occurs when new substances are formed from existing substances. This process is called a chemical reaction.
In a chemical reaction, one or more substances change into one or more different substances. During the reaction, the atoms of the original substances are rearranged to form other substances.
The original substances in a chemical reaction are called reactants. These substances react, or go through a chemical change.
The substances that are formed in a chemical reaction are called products. These substances are produced by the chemical reaction.
So, in a chemical reaction, reactants go through a chemical change to form products.
Read the underlined text carefully. Look for information about what happens to beeswax in this chemical reaction.

The underlined text tells you that when beeswax and oxygen combine, carbon dioxide and water are formed. When beeswax and oxygen react, or go through a chemical change, their atoms are rearranged to form carbon dioxide and water. Because beeswax reacts in this chemical reaction, beeswax is a reactant.
