10. The partial pressure of water vapor in a greenhouse is 139.0 mm Hg, which is 18% of the total pressure. What is the
total pressure in the greenhouse?

Acertain atom has 22 protons and 19 electrons. this atom loses an electron. the net charge on the atom is now 4+1+01-4-. if this same atom with 22 protons and 19 electrons were to gain 3 electrons, the net charge on the atom would be 3+2+02-3-.
