Calculate the approximate enthalpy of the reaction in joules. estimate that 1.0 ml of vinegar has the same thermal mass as 1.0 ml of water. it takes 4.2 joules to change 1.0 grm (1.0 ml) of water 1.0 celcius. is it endotherrmic or exothermic? volume of vinegar 25 ml, initial temp of vinegar 17 celcius and final temp is 14 celcius.

Pauling and lewis questioned the extreme definitions of bonds. they wondered if bonds might be described somewhere in between the two extremes (covalent and ionic). on the basis of experimental data,pauling confirmed that bonds could be ionic, covalent, and for those, in between, exhibit a degree of ionic character. he theorized that the major factor was how strongly the atoms in the bond attracted the electrons. pauling called this factor - the tendency of an atom to attract electrons in a bond.
