Pentaerythritol tetranitrate (abbreviated PETN, chemical formula C5H8N4O12) is an explosive material with a structure that is very similar to nitroglycerin. It is one of the components of plastic explosives such as Semtex. The explosion of PETN can be represented by: C5H8N4O12(s)→2CO(g)+4H2O(g)+3CO2(g)+2N2(g) A plastic explosive charge is formed into a cylinder about 30 cm long and about 2 cm in diameter. It weighs about 246 grams and is 58.5% PETN by mass. What is the total number of moles of gas produced when this plastic explosive charge explodes? mol gas Sulfuric acid (H2SO4) reacts with sodium bicarbonate (NaHCO3) to produce sodium sulfate, carbon dioxide and water. If 1.45 L of 4.50 M H2SO4 is spilled and 1.00 kg NaHCO3 (MM=84.01 g/mol) is available to clean up the spill, is there enough sodium bicarbonate to neutralize the spilled sulfuric acid? No, and there is about 10% less NaHCO3than needed. Yes, and there is about 10% more NaHCO3than needed. No, and there is about 20% less NaHCO3than needed. Yes, and there is precisely enough NaHCO3. Yes, and there is about 20% more NaHCO3than needed.
