1.	sulphur burns in oxygen to give sulphur dioxide .if 16g of sulphur burns in 'x'cc of oxygen . calculate the amount of potassium nitrate which must be heated to produce 'x' cc of oxygen.[S=32, K=39, N=14,O=16]
Answer» Hii dear ___________❤️❤️❤️ good morning_______________✌️✌️✌️✌️ S + O2 → SO2 1mol 1mol 1mol Moles of S reacted = 16g/32G/MOL = 0.5 mol 0.5 mol of S needs 0.5 mol of Oxygen, {To complicate the question x CC is mentioned in the question, which has no SIGNIFICANT use.} So we know that Sulphur burns in 0.5 mol Oxygen. The thermal decomposition of Potassium nitrate : 2KNO3 → 2KNO2 + O2 2mol 1 mol [2 x 101g] 32g O2 1 mol of O2 is produced by 2 mol of KNO3 0.5 mol will thus be produced by 1 mol of KNO3 Thus 1mol of KNO3 is required to produce the given amount of Oxygen. 1mol of KNO3 = molar mass of KNO3 = 101g Hence 101g of KNO3 is required.
