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.
The answer must show the lowest number of significant number of significant places in the decimal region
Explanation:
5.67 + 0.00032 adds up to 5.67 because the least number of significant figures in the decimal place 2.
- To add up two numbers, that are in decimal places.
- Identify the number of significant figures in them
- Their addition should sum up to a value no more than the significant figures to the right of the decimal having the lowest accuracy.
5.67
+ 0.00032
to the right of the decimal, they have two significant numbers.
The answer should also be this way.
