two flasks are connected with a stopcock. flask A has a volume of 4.5 L and contains nitrogen gas at a pressure 1.75 atm. flask B has a volume of 8.2 L and contains oxgen gas at a pressure of 2.25 atm. when the stopcock between the flaskes is opened and the gases are free to mix, what will the pressure be in the resulting mixture

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.
