Acetone peroxide, C₉H₁₈O₆(s), is a powerful but highly unstable explosive that does not contain nitrogen. It can pass undetected through scanners designed to detect the presence of nitrogen in explosives like TNT (trinitrotoluene, C₇H₅N₃O₆) or ammonium nitrate. Write a balanced equation for the combustion (burning in oxygen) of acetone peroxide producing steam and carbon dioxide. What pressure is generated in a 2.00-L bottle when 4.00 g of acetone peroxide is ignited to 555°C and burned in air? Assume 100% combustion.
