### Binary Compounds: Formula Writing #### Exercise 2.102 Write the chemical formulas for the following binary compounds: 1. **Potassium chloride** 2. **Tin(II) bromide** 3. **Calcium oxide** 4. **Barium chloride** 5. **Aluminum hydride** To assist with understanding, here are some general steps to follow when writing chemical formulas for binary compounds: ### Steps to Write Formulas for Binary Compounds 1. **Determine the symbols of the elements:** - Identify the chemical symbols for each element in the compound. 2. **Identify the charges:** - Determine the valence or oxidation state for each element. 3. **Balance the charges:** - Adjust the number of each type of ion so that the compound forms electrically neutral. For students, practicing these steps with the provided examples will enhance understanding of binary compound formulas. Feel free to use a periodic table for reference and ensure that the resulting compound is neutral in charge. ### Example: - For **Potassium chloride**: - **Element Symbols**: Potassium (K) and Chlorine (Cl) - **Charges**: Potassium has a +1 charge (K⁺) and Chlorine has a -1 charge (Cl⁻) - **Balanced Formula**: KCl By following these steps, try to write the formula for the remaining compounds provided in Exercise 2.102.
