A sentence might be Hydrogen and oxygen combine to form water (**H2O**). To turn this into an equation you must first find the symbols for hydrogen and oxygen. They are **H** and **O**. Hydrogen and oxygen are both diatomic so they are written with a **2** to the right of them- **H2, O2**. Then you add them together **H2 + O2 > H2O**. Then after that you must balance the equation. When you balance an equation that means that you need the same number of **H**'s on both sides and the same number of **O'**s on both sides. This equation is not yet balanced because there are two **O**'s on the left and only one on the right. So then you have to add a **2** in front of the **H2O** on the right. But then there are only two H's on the left and **4 H's** on the right. Then you must equal the number of H's so you must put a **2** in front of the **H** on the left. The final Equation should look like **2H2 + O2-> 2H2O**.
