What is the pressure applied when a force of 200 N acts on an area of 0.5 m??​

P = 200/5 = 40 Pa.

If this helped hit the heart. Have a nice day :-)

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
