A gas at 55.0°C occupies a volume of 3.60L. What volume will it occupy at 30.0° C? Pressure is constant.

n has four pairs of electrons in the valence shell, electrons repel one another ,n has 7 protons in its nucleus, and since n has 7 protons, it must fill the second shell, giving it 4 pairs of electrons. the electrons form 3 bonds and 1 lone pair of electrons. each pair of electrons repels the other pairs, so they are equally far apart.

so all of the above

the answer is a and have a great day
