    Does a neutralisation reaction with higher volumes create more heat?

    In a multiple choice question, I assumed that half the volume of 2 acids and bases with constant concentrations would mean half the temperature. The answer suggests there is no change. Can anyone explain this? I can't understand how presumably half the molecules can produce the same amount of...

    The more the electron is away from the nucleus in higher shells, does it only absorb

    The more the electron is away from the nucleus in higher shells, does it only absorb EM waves with higher energy, like ultra violet waves.? Like in glass, light does not get absorbed by the electron but ultra violet does. I am thinking the further away the electron is, then it only absorbs...

    Which of these has higher boiling point?

    Which one has higher boiling point, phosphorus pentachloride or sulphur hexafluoride? So, phosphorus pentachloride is shaped as a trigonal bipyramid. It is not polar and the forces that act between molecules are London dispersion forces. Sulphur hexafluoride is shaped as octahedral, it is not...
