Its decomposition may be represented by 4C3H3N3O9 → 6N2 + 12CO, + 10H20 + O2 This reaction generates a large amount of heat and gaseous products. It is the sudden formation of these gases, together with their rapid expansion, that produces the explosion. ok (a) What is the maximum amount of O, in grams that can be obtained from 7.50 × 10² g of nt nitroglycerin? g ences (b) Calculate the percent yield in this reaction if the amount of O, generated is found to be 24.5 %Part D: Food Calories Naked Juice Serving size 240 mL D1.
