Consider the following statements: 1. Baking soda is used in fire extinguishers. 2. Quicklime is used in the manufacture of glass. 3. Gypsum is used in the manufacture of Plaster of Paris. Which of the statements given above is/are correct?

The correct answer is D because all three statements are scientifically accurate: Statement 1 is correct. Baking soda, or sodium bicarbonate, is used in soda-acid fire extinguishers. When it reacts with an acid, it releases carbon dioxide gas, which helps extinguish the fire by cutting off the oxygen supply. Statement 2 is correct. Quicklime, or calcium oxide, is a primary raw material in the glass industry. It is melted with silica sand and soda ash to produce common soda-lime glass, providing the glass with chemical durability and hardness. Statement 3 is correct. Gypsum is the raw material used to produce Plaster of Paris. When gypsum is heated to about 150 degrees Celsius, it loses part of its water content to become calcium sulfate hemihydrate, commonly known as Plaster of Paris.
