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:
10.32 moles of ammonia NH₃
Explanation:
From the question given above, the following data were obtained:
Number of molecules = 6.21×10²⁴ molecules
Number of mole of NH₃ =?
The number of mole of NH₃ can be obtained as follow:
From Avogadro's hypothesis,
6.02×10²³ molecules = 1 mole
Therefore,
6.21×10²⁴ molecules = 6.21×10²⁴ / 6.02×10²³
6.21×10²⁴ molecules = 10.32 moles
Thus, 6.21×10²⁴ molecules contains 10.32 moles of ammonia NH₃
