determine δh for the third reaction from the information given. ba(s) o2(s) ↔ 2 bao(s) δh = -1107 kj ba(s) co2(g) 1/2 o2 ↔ baco3(s) δh = -822.5 kj bao(s) co2 ↔ baco3 δh = ?

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
