A 6.55 g sample of C6H5NH2 was combusted in a bomb caloriemeter. If the temp rose by 32.9 degreese C use the info below to determine the heat capacity of the calorimeter (Ccal)
C6H5NH2 = 93.13 g/mol, O2 = 32.00 g/mol CO2 = 44.01 g/mol H20 = 18.02 g/mol NO2 = 46.01 g/mol
4 C6H5NH2 + 35 O2 → 24 CO2 = 14 H20 = 4 NO2
At 700 K the equilibrium constant for the reaction is Kp = 0.76. CCl4(g)-> C(s) + 2 Cl2(g) A flask is charged with 2.00 atm of CCl4, which then reaches equilibrium at 700 K. (a) What fraction of the CCl4 is converted into C and Cl2?
A gaseous mixture of NO2 and N2O4 is in equilibrium. If the concentration of N2)4 is 5.3 x 10^-5 M, what is the concentration of NO2? 2 NO2 (g) ==> N2O4 (g) Kc = 170
A 3.46 g sample of zinc heated to 95.4 C was dropped into 50 g of water at 20.7 C in a calorimeter. The temperature rose to 21.2 C. What is the specific heat of zinc?

Compute the amount of heat evolved in the oxidation of 32.0 grams of Fe at the temperature 25 oC and pressure 1 atm pressure ( ΔHfo(Fe 2 O 3 ,s) = -824kJ/mol)
what mass of (NH4)2SO4 must be dissolved in 0.100L of 0.350M NH3 to produce a buffer solution with pH 10.05?
A 1L steel tank is fitted with a safety valve that opens if the internal pressure exceeds 850 torr. It is filled with helium at 23 oC and 0.991 atm and placed in an oil bath.
In one episode of the 1960s television sitcom, Gilligan's Island, the famous professor constructed voltaic cells to use as substitues for their radio's dead batteries.
