what is the difference between a chemical bonds formed in the molecules of 02 and the chemical bonds formed in crystals of a NaCI

O2 is a covalent substance while NaCl is an ionic substance

Explanation:

In O2 molecule, the bond is between 2 oxygen atoms which are non - metals. Thus, this is a covalent bond since it involves 2 non metals.

Whereas, for the NaCl molecule, the bond is between a metal sodium (Na) and a non metal Chloride(Cl) and thus we can say this is an ionic bond.

Thus the difference is that O2 is a covalent substance while NaCl is an ionic substance.

relative humidity is a measure of the amount of moisture in the air relative to the total amount of moisture the air can hold.

so d

what is the question here. i think you messed up.
