The correct Answer is:
To determine the name of the compound represented by the formula `Na2CO3.10H2O`, we can follow these steps: ### Step 1: Identify the Components of the Formula The formula `Na2CO3.10H2O` consists of two parts: - `Na2CO3`: This part indicates that the compound contains sodium (Na), carbon (C), and oxygen (O). - `10H2O`: This indicates that there are 10 water molecules associated with the compound. ### Step 2: Analyze the Anhydrous Part The `Na2CO3` part is sodium carbonate. Sodium carbonate is a well-known compound that can exist in anhydrous form (without water) and in hydrated forms. ### Step 3: Understand the Hydration The `10H2O` indicates that this sodium carbonate is in its decahydrate form, meaning it has 10 water molecules attached to each formula unit of sodium carbonate. ### Step 4: Combine the Information When sodium carbonate is hydrated with 10 water molecules, it is commonly known as washing soda. ### Final Answer Thus, the name of the compound `Na2CO3.10H2O` is **washing soda**. ---
