In the 1860's the Central Pacific Railroad company employed the chemist James Howden to make an explosive capable of blasting through the granite mountains of the Sierras. The railroad needed tunnels for their train to pass through. James Howden built a nitroglycerin producing lab on Donner Pass where he would make the explosive compound on command. Nitroglycerin has the chemical formula C3H5N3O9. When it is detonated, it decomposes into carbon dioxide, water, oxygen and nitrogen. What is the theoretical yield for moles of nitrogen gas produced upon detonation of 1.320 tons of nitroglycerin? There are 907185 grams in 1 ton and nitroglycerin has a molar mass of 227 g/mol. Do not include decimals in your answer.

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
