Now try the following three examples: elements formula name barium phosphorus The element barium is an Alkaline Earth Metal, which loses two electrons (2 ) and phosphorus is in Group V, which gains three electrons (3-). It will have the ending "ide". silver carbon The element silver is a transition metal, with only one stable ionic state. Carbon is in Group IV, which gains four electrons. A. cadmium B. hydrogen

Refrigerant-134a flows through a carnot heat pump cycle at 0.5 kg/s. it is known that the maximum absolute temperature in the cycle is 1.1 times the minimum absolute temperature, and the net power input to the cycle is 2.5 kw. if the refrigerant changes from a saturated vapor to a saturated liquid during the heat rejection process, determine the maximum magnitude of the enthalpy of vaporization for this process in kj/kg (with 3 significant figures).
