The explosion of 2.00 mol of solid trinitrotoluene (tnt; c7h5n3o6) with a
volume of approximately 274 ml produces gases with a volume of 448 l at room temperatur and 1.0 atm pressure. how much pv work in kilojoules is done during the explosion?
2 c7h5n3o6(> 12 co(g) + 5 h2(g) + 3 n2(g) + 2 c(s)

-45.37 kJ

Explanation:

The work done for the explosion of 2 moles of TNT can be determined by taking the product of the pressure and change in volume. In addition, the explosion of a substance is endothermic in nature. Thus, we have the equation for work done as:

W = P*dV

Where:

W = work done (L*atm)

P = pressure (atm) = 1.0 atm

dV = change in volume (L) = 0.274 - 448 = -447.726 L

Therefore,

W = 1.0 * (-447.726) = -447.726 L*atm

1 L*atm is equivalent to 101.325 J

Thus, the work done in kJ is:

-447.726*101.325/1000 = -45.37 kJ

to make a supersaturated solution, make a saturated solution of sugar by adding 360 grams of sugar to 100 ml of water at 80 degrees celsius. when the water cools back down to 25 degrees, that 360 grams of sugar will still be dissolved even though the water should only dissolve 210 grams of sugar.
