When a neutralization reaction was carried out using 100.00 mL of 0.7890M NH(3) water and 100.0 mL of 0.7940M acetic acid, change in temp was found to be 4.76 degree celcius. THe specific heat = 4.104 J g^-1 K^-1 and density was 1.03 g mL^-1. The calorimeter constant was 3.36 J K^-1.
Calculate delta H(neutzn) for the reaction of NH(3) and acetic acid and the percent error for the correct deltaH(neutzn) if a change in temp of 4.76 degree celcius had been used.
Calculate the amount of energy in the form of heat that is produced when a volume of 3.75 L of SO2(g) is converted to 3.75 L of SO3(g) according to this process at a constant pressure and temperature of 1.00 atm and 25.0 °C. Assume ideal gas beha..

paris is one of my favorite european cities. this question relates to a possible problem with parisian drinking water.
Glycolysis and gluconeogenesis are reciprocally regulated at the steps that interconvert fructose-6-phosphate and fructose-1,6-bisphosphate.
Camphor (C10H16O) is a natural compound found in the wood of camphor laurel, an evergreen native to southeast Asia. Borneol (C10H18O) and isoborneol (C10H18O) are similar to camphor
