Question

Answer 1.3 (6pts). What is the energy, in kJ/mol, of photons with a wavelength of 976.9 nm? Answer: 1.4 (6pts). For the left-hand table give the quantum numbers for the last electron added or identify the element where the quantum number for the last electron added is given. Assume that all orientations are fixed so that subshells fill from lowest to highest. For the right-hand table give the number of electrons expected for the quantum set provided,- indicates the field may have any value. ml ms Element Quantum Set Number of electrons n 1 (2,) 2 (4, +1/2) 3 (5,1,0,-) 4 (5, 4,,+1/2) 5 (6, 6 (3,0,-) 1 Lead 2 Cobalt 3 Silicon 4 1 4 2 1-1/2 1-1/2 0+1/2 4 6 3 1.5 (6pts). What are the four basic assumptions of the ideal gas law 1 2. 3. 4

Answer 1

THANK YOU VERY MUCH .HOPE THIS WILL HELP YOUANS-1.5:For a gas to be “ideal” there are four governing assumptions:

1.The gas particles have negligible volume. 2.The gas particles are equally sized and do not have intermolecular forces (attraction or repulsion) with other gas particles.

3.The gas particles move randomly in agreement with Newton’s Laws of Motion. 4.The gas particles have perfect elastic collisions with no energy loss.
