A fountain pen, which has a total volume of 2.4 cm is half full with ink at ground level where the pressure is
780.0 mm Hg. It is put into the pocket of a pilot who flies to an altitude where the pressure is 520.0 mm Hg.
How much ink leaks out of the pen?

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.

Hno3(aq) → h+(aq) + no3−(aq). picture ii best represents the strong acid hno3. strong acids are strong electrolytes

All the elements are arranged by melting points on the periodic table. in row they go from metals to gasses. in the row from sodium to argon, sodium is more reactive than the one on its right, magnesium.
