Nitroglycerin (C3H539 4C35392222NO) is a powerful explosive. Its decomposition may be represented by
HNO → 6N + 12CO + 10HO + O
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.
(a) What is the maximum amount of O2 in grams that can be obtained from 7.50 × 102 g of nitroglycerin?
(b) Calculate the percent yield in this reaction if the amount of O2 generated is found to be 24.0 g.
Suppose 1.07 g of FeCl3 is placed in a 75.0 mL volumetric flask, water is added, the mixture is shaken to dissolve the solid, and then water is added to the calibration mark of the flask. Calculate the molarity of each ion present in the solution.
Prepare 100 mL (total volume) of a buffer solution that is 0.025 M in carbonic acid, pH 7.25. You have solid H2CO3 and solid NaHCO3. Calculate how many grams of H2CO3 and HCO3- you need to weigh out to prepare this solution.
