The correct Answer is:
To evaluate the truth of the given statements, let's analyze each statement step by step. ### Step 1: Analyze Statement 1 **Statement:** Sodium silicate is called water glass. **Explanation:** Sodium silicate is indeed referred to as water glass. It is formed by fusing silicon dioxide (SiO2) with sodium oxide (Na2O), and when dissolved in water, it creates an aqueous solution that resembles glass. When this solution dries, it forms a glass-like solid. Therefore, this statement is **True**. ### Step 2: Analyze Statement 2 **Statement:** Salts of lead are poisonous in nature. **Explanation:** Lead and its compounds are well-known for their toxicity. Lead exposure can cause severe health issues, particularly affecting the nervous system, kidneys, and other organs. Children are especially vulnerable to lead poisoning, which can lead to developmental issues. Hence, this statement is also **True**. ### Step 3: Analyze Statement 3 **Statement:** Producer gas is a mixture of CO and N. **Explanation:** Producer gas is generated from the gasification of carbonaceous materials like coal. It primarily consists of carbon monoxide (CO) and hydrogen (H2), along with some nitrogen (N2) and other gases. However, the main components are CO and H2, not just CO and N. Therefore, this statement is **False**. ### Conclusion Based on the analysis: - Statement 1: True - Statement 2: True - Statement 3: False Thus, the correct answer is that the first two statements are true, and the third statement is false. ### Final Answer **The correct option is:** True, True, False. ---
