Answer:
Explanation:
Oxygen molecules are formed as a result of covalent bonding between two atoms of oxygen. There is a sharing of two valence electrons so as to complete their respective octets. This is also similar to the formation of nitrogen molecules.
Oxygen has greater force of attraction because, the electronegativity of oxygen is the second strongest among the elements. Electronegativity deals with the relative tendency of an atom to attract electrons to itself. Therefore, the shared electrons are being greatly pulled by the two atoms of oxygen. The electronegativity of nitrogen is not as great as that of oxygen.
Answer:
Gases have two properties that set them apart from solids and liquids. First, gases spontaneously expand to fill the container they occupy, no matter its size. In other words, a gas has no fixed volume or shape. Secondly, gases are easily compressible.

The question is in incomplete, so here is the complete question:
Nucleic acids are polymers of just 4 different monomers in a linear arrangement. How many different nucleic acid polymer sequences are possible when the polymer contains 30 monomers?
Polymers are biomolecules formed by monomers. For nucleic acid, like DNA and RNA, as 4 monomers are necessary to "create" 1 polymer, a polymer containing 30 monomers can "produce" 7 different nucleic acid sequences.
