Predict the molecular geometries of all the following compounds using VSEPR: a) ${\mathrm{SiF}}_4$ b) ${\mathrm{OF}}_2$ c) ${\mathrm{OCF}}_2$ (with respect to the carbon atom, which is central) d) ${\mathrm{PCl}}_3$ e) ${\mathrm{CO}}_2$ Select the appropriate terms which describe the nature of $?U$ (with respect to the system) in each scenario. System absorbs heat, work performed on the system System absorbs heat, work performed by the system on the surroundings System emits heat, work performed on the system System emits heat, work performed by the system on the surroundings
