Homework answers / question archive / Could I have help with these questions? Based off the provided data on picric acid, the questions follow the data
The theoretical enthalpy is -15186 kJ/mol.
Molar mass of picric acid = 229.1 g/mol
The volume of 1 g of picric acid is 0.89 L.
The amount of heat produced at 1 kg is 16552.7 kJ
The volume of gas produced at 1 g and the volume is 0.89 L is -0.0902 KJ.
1. In Discussion # 2, you determined the theoretical enthalpy of your explosive reaction. This is can also be termed the heat of explosion, but when it is termed heat of explosion, the units are traditionally kJ/kg of substance. Convert your enthalpy of reaction (kJ/mol) to heat of explosion (kJ/kg) using the molar mass of your explosive. List that value here and use it to calculate the explosive energy of 5.00 kg.
2. In Discussion #1, you calculated the volume of gas that your explosive would produce if 1 g of it was used, assuming standard temperature and pressure (STP)and any water produced in the gaseous state. Is this actually accurate, as the gas is usually heated as a result of the explosion, resulting in a much larger volume of gas? But what temperature will the gas reach? Calculate the final volume of the gas produced from 1.00 g of your explosive using Charles' Law, and assuming your explosion reaches a temperature of 3000 K.
Remember Charles' law? V1/T1 = V2/T2
3. Explosive power is defined as the heat of explosion (kJ/kg) x the volume of gases (L/g) produced (at final temperature). Calculate the explosive power of your substance. Use the volume of your gas produced after heating by "heat of explosion".
