Calculate the lattice energy of NaCl. Heat of sublimation is 108kj/mol and Heat of NaCl is -411kj/mol. Energy to dissociate .5 mole of Cl2to an atom of Cl is121.4 kj/mol.
The solubility of AgCl(s) in water at 25 degrees C is 1.33*10^-5 mol/L and its deltaH0 of solution is 65.7 kJ/mol.
A solution contains 25 mmol of H3PO4 and 10. mmol of NaH2PO4. What volume of 2.0 M NaOH must be added to reach the second equivalence point of the titration of the H3PO4 with NaOH?
Calculate the pH at the equivalence point for titrating 0.170 M solutions of each of the following bases with 0.170 M HBr. a)sodium hydroxide
When 1 mol of a gas burns at constant pressure, it produces 2414J of heat and does 4kJ of work. 1. Identify \Delta E for the process. Express your answer using one significant figure.
How do you estimate energy change using bond reactions in a complete methane combustion
Suppose that this individual now decides to give one-eighth of a percent (0.125 ) of her new net worth to charity. How many dollars are given to charity? The answer is not 10.0025 or 12.5. I have been working at this problem and just need to figur..
Suppose that coal of density 1.5 g/cm3 is pure carbon. (It is, in fact, much more com- plicated, but this is a reasonable ?rst ap proximation.)
