Answer: b. 322.5 mL
Explanation:assume constant pressure, then
693/(273.15+45) = v/(273.15-125)
v= 693*148.15/318.15 = 322.7
Covalent bonds are also called molecular bonds. These chemical bondings involves atoms sharing electron pairs. Covalent bonding usually happen between 2 non-metals. Non metals are usually found in the left and right most sides of the periodic table. Hence, the answer will be A. N and O since both elements are non-metals.
