Gizmo Warm-up In a chemical reaction, reactants interact to form products. This process is summarized by a chemical equation. In the Balancing Chemical Equations Gizmo, look at the floating molecu... les below the initial reaction: H2 + O2 ? H2O. 1. How many atoms are in a hydrogen molecule (H2)? 2 2. How many atoms are in an oxygen molecule (O2)? 2 3. How many hydrogen and oxygen atoms are in a water molecule (H2O)? 3 4. In general, what does a subscript (such as the “2” in H2) tell you about the molecule? How many molec ules there are 5. A chemical equation is balanced if the number of each type of atom on the left side is equal to the number of each type on the right side. Is this reaction balanced? [Show More]
