Answer in General Chemistry for ash #155545

1. 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.
2. Write a balance equation for the combustion (burning in oxygen) of acetone peroxide producing steam and carbon dioxide.
3. What pressure is generate in a 2.00 L bottle when 5.00 g of acetone peroxide is ignited to 555℃ and burned in air?  Assume 100% combustion

The balanced equation for combustion of acetone peroxide is;

2C₉H₁₈O₆ + 21O₂ “to” 18CO₂ + 18H₂O

Pressure generated the bottle

Given that;

PV = nRT, hence

P= “dfrac{nRT}{V}”

n = moles of acetone = “dfrac{mass}{molar mass of a gas} =” “dfrac{5g}{222.24g/mol(dimer)}” = 0.0225mol

R = 0.08206L*atm*mol^-1K^-1

T = 555oC + 273K = 828K

P = “dfrac{0.0225mol x 0.08206Latmmol^-1K^-1 x 828K}{2.00L}” = 0.76423 atm
