Given: Mass m = 0.61 Kg;      Displacement  x = 4.0 cm  or  x = 0.04 m

Required:  Spring constant  k = ?

Formula:  F = kx

                k = F/x

                k = (0.61 Kg)(9.8 m/s²)/0.04 m

                k = 149.45 N/m

H2O consists of polar molecules. CO2 consists of nonpolar molecules. How do chemists explain this difference?
Vadim26 [7]
C. Oxygen has a different attraction for electrons in H2O than in CO2

the covalent bond between Hydrogen-Oxygen and Carbon-Oxygen is different because the difference of electronegativity (the tendency of an atom to attract a shared pair of electrons towards itself) between Hydrogen and Oxygen is a lot higher than the difference of electronegativity between Carbon and Oxygen. This difference in electronegativity results in separation of partial electric charge creating polar bonds and giving the molecule a polarity.
