The heat of vaporization ΔHv of benzene C6H6 is 44.3 kJ/mol.
Calculate the change in entropy ΔS when 229. g of benzene boils at 80.1 °C. Be sure your answer contains a unit symbol. Round your answer to 3 significant digits.

In 2002, the rare earth elements mine in mountain pass, california was closed because

Most materials are not magnetic because their magnetism has worn off. their magnetic domains are arranged randomly. they lack magnetic fields. earth’s heat has destroyed their magnetism.

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.
