Phosphorus has three electrons in its 3p sublevel and sulfur has four. phosphorus should have the lower ionization energy but it does not, sulfur does. why?
a. because sulfur has more electrons, they are further from the nucleus and thus easier to remove and form an ion.
b. sulfur has 2 of its electrons paired in the 3p sublevel. the mutual repulsion of their negative charges makes them easier to remove, or "ionize."
c. since sulfur has more electrons, it has more chances to form an ion.
d. phosphorus has 2 of its electrons paired in the 3p sublevel, which makes them harder to remove, or "ionize."

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
