Use the following data to estimate the lattice energy for potassium oxide. 2K (s) + 1/2 O2 (g) â K2O (s)
Enthalpy of formation of K2O = -363.2 kJ/mol
Bond enthalpy for O2 = 498 kJ/mol
1st electron affinitty of O = -141 kJ/mol
2nd electron affinity of O = 745.2 kJ/mol
enthalpy of sublimation for K = 89.0 kJ/mol
1st ionization energy of K = 418.8 kJ/mol
2nd ionization energy of K = 3052.0 kJ/mol

An electrons position cannot be known precisely only it's probability of being in a certain location can be known

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?

Listenbase your answer to the question on the information below.nuclear radiation is harmful to living cells, particularly to fast-growing cells, such as cancer cells and blood cells. an external beam of the radiation emitted from a radioisotope can be directed on a small area of a person to destroy cancer cells within the body.cobalt-60 is an artificially produced radioisotope that emits gamma rays and beta particles. one hospital keeps a 100.0-gram sample of cobalt-60 in an appropriate, secure storage container for future cancer treatment.which choice represents the correct product for the beta decay of the co-60? fe-60ni-60fe-61ni-61
