How electronegativity relates to polar bonding

Electrons in a polar covalent bond are shifted toward the more electronegative atom; thus, the more electronegative atom is the one with the partial negative charge. The greater the difference in electronegativity, the more polarized the electron distribution and the larger the partial charges of the atoms.

the answer is a. co2, this would be colder than the : )

explanation:

the dependant variable is spilled water

the independent is the heat
