- Mr. Roy, the principal of a reputed school organized a seminar in which he invited parents and principals to discuss the serious issue of diabetes and depression in students. They all resolved this issue by strictly banning the junk food in schools and to introduce healthy snacks and drinks’like soup, lassi, milk, etc. in school canteens. They also decided to make compulsory half an hour physical activities for the students in the morning assembly daily. After six months, Mr. Roy conducted the health survey in most of the schools and discovered a tremendous improvement in the health of students. After reading the above passage, answer the following: What are the values (at least two) displayed by Mr. Roy? As a student, how can you spread awareness about this issue? What are tranquilizers? Give an example. Why is the use of aspartame limited to cold foods and drinks?The combustion of ammonia in the presence of excess oxygen yields NO2 and H2O: 4 NH3 (g) + 7 O2 (g) → 4 NO2 (g) + 6 H2O (g) The combustion of 294 g of ammonia consumes __________ g of oxygen.
