75.0 degrees Celsius = 75.0 + 273 = 348 K.
Assuming pressure is held constant,
Hope I helped with the answer to your question ;)
Atoms 'like' to have 8 valence electrones. sodium has one electron 'in excess' and chlorine 'lacks' in one. so they just exchange :) both are happy. then the ionic bond is formed because chlorine is now charged negative (additional electron) and sodium is charged positive (gave up one electrone) - the opposite charges cause electrostatic pull. many atoms, many bonds and thats how salt is built.
The relationship between electron orbits and light emission Bohr postulate is The energy difference between two electron orbits would equal the energy of an emitted photon.
What do you mean by electron orbit?
The path of an electron around the nucleus of an atom. In atomic theory and quantum mechanics, an atomic orbital is a function describing the location and wave-like behavior of an electron in an atom.
This function can be used to calculate the probability of finding any electron of an atom in any specific region around the atom's nucleus.
What do you mean by Light emission?
Light can be produced by matter which is in an excited state and, as we will show, excitation can come from a variety of sources.
The atoms and molecules that make up matter typically emit light at characteristic energies. The light emission can be spontaneous or stimulated.
