This passage describes a chemical reaction. Read the passage. Then, follow the instructions below.
Have you ever eaten food that was cooked on a grill? Some grills are powered by propane gas. The propane combines with oxygen in the air to make carbon dioxide gas and water vapor. This process releases energy in the form of heat, creating a flame that cooks the food.
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 propane in this chemical reaction.
Have you ever eaten food that was cooked on a grill? Some grills are powered by propane gas. The propane combines with oxygen in the air to make carbon dioxide gas and water vapor. This process releases energy in the form of heat, creating a flame that cooks the food.
The underlined text tells you that when propane and oxygen combine, carbon dioxide and water are formed. When propane and oxygen react, or go through a chemical change, their atoms are rearranged to form carbon dioxide and water. Because propane reacts in this chemical reaction, propane is a reactant.
