Questions Based on High Order Thinking Skills (HOTS) 44. When a piece of limestone reacts with dilute HCI, a gas X is produced. When gas X is passed through water then a white precipitate Y is formed. On passing excess of gas X, the white precipitate dis forming a soluble compound Z. (a) What are X, Y and Z ? (b) Write equations for the reactions which take place: (1) when limestone reacts with dilute HCI (if) when gas X reacts with lime water to form white precipitate Y (fi) when excess of gas X dissolves white precipitate Y to form a soluble compound Z 45. If someone is suffering from the problem of acidity after overeating, which of the following would suggest as remedy? Lemon juice, Vinegar, Baking soda solution Give reason for your choice.
