Help please What is the pressure of a mixture of oxygen, nitrogen, and carbon dioxide gases if the pressures of these gases are as follows: Po2 = 300 atm, PN2 = 50 atm, and Pcoz = 200 atm?​

yes it is balanced

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.
