6.82 A 2.10-mole sample of crystalline acetic acid, ini-

tially at 17.0°C, is allowed to melt at 17.0°C and is

then heated to 118.1°C (its normal boiling point) at

1.00 atm. The sample is allowed to vaporize at.

118.1°C and is then rapidly quenched to 17.0°C, so

that it recrystallizes. Calculate AH° for the total pro-

cess as described.

Which statement correctly describes metallic bonds? a. they form when certain atoms lose electrons and other atoms gain electrons. b. they involve an attraction between anions and cations. they always involvpoth a metal and a nonmetal. d. they can only form between atoms of the same element. e. they form because electrons can move freely between atoms.
