A new compund has been analyzed and a .47191g sample has been found to contain .1929g C, .01079 of H., .08566g of oxygen, and .1898g of Cl. Find the empirical formula
The molecular weight of [Cu(NH3)x]SO4*H2O when x=1 is equal to 194.68 g/mol. the molecular weight of CuSO4 * 5H2O is equal to 249.72 g/mol.
Calculate the energy levels of the pi-network in octatetaene, C8H10, using the particle in the box model. To calculate the box length, assume that the molecule is linear and use the values 135 and 154pm for C--C and C-C bonds.
at 100.0 degrees celsius and 1.00 atm delta h 40.6 for the vaporization of water. estimate delta g for the vaporization
How would the value of the atomic mass of the metal calculated be affected if the hot metal sample cooled off before it was transferred to the water in the calorimeter. would it be too high or too low
The tmeperature s increased to 1200 K, so that all CaC204 decomposes to form CaO according to the reactions, The density of the gas mixture at 1200K was 0.70501 g/L. What was the mass of the calcium oxalate initially placed in the vessl?
