The correct Answer is:
To solve the question "Mercury sticks to glass when it comes in contact with," we need to analyze the options provided and understand the chemical interactions involved. ### Step-by-Step Solution: 1. **Understanding Mercury's Properties**: - Mercury (Hg) is a liquid metal that does not readily wet surfaces like glass. This means it typically forms beads rather than spreading out. 2. **Analyzing the Options**: - **Option 1: Water**: Mercury does not react with water. Therefore, it will not stick to glass when in contact with water. - **Option 2: Nitric Acid (HNO3)**: When mercury reacts with nitric acid, it forms mercury(II) nitrate (Hg2(NO3)2). However, this reaction does not lead to mercury sticking to glass. - **Option 3: Iodine**: Mercury can react with iodine to form compounds like Hg2I2. However, this also does not result in mercury sticking to glass. - **Option 4: Ozone (O3)**: When mercury comes into contact with ozone, it reacts to form mercury(I) oxide (Hg2O) and oxygen (O2). The formation of mercury oxide allows mercury to stick to glass due to the "tailing effect." 3. **Conclusion**: - The correct answer is that mercury sticks to glass when it comes in contact with **ozone**. ### Final Answer: Mercury sticks to glass when it comes in contact with **ozone**. ---
