The explosive nitroglycerin decomposes rapidly upon ignition or sudden impact according to the following balanced equation: 4C3H5N3O9 (l) --> 12 CO2 (g) + 10H2O (g) + 6N2 (g) + O2 (g)
DH RXN = -5678 kJCalculate the standard enthalpy of nitroglycerin
A. A student places 2.10 L of water in his dormitory room, which has the volume of 4.06 x10^4 L. He seals the room and waits for the water to evaporate. At 25 deg C, the density of water is 0.997 g/mL
The background section describes why you want the bleach to be far in excess of the dye. State how much greater the bleach should be to be considered in large excess. If the due is 1 x 10-5 M how much can the bleach be diluted before you no longer..
