Chemical Properties of Group 17 Elements - Class Notes

Nettet30. mar. 2024 · Electron gain enthalpy of 17th group elements are -349, -328, -325, -296, -270 KJ\/mole (not in order). ... The electron gain enthalpy can be negative or positive depending on the energy released and absorbed during the addition of electrons. NettetSulfamethazine is a representative member of the sulfonamide antibiotic drugs; it is still used in human and veterinary therapy. The protonation state of this drug affects its aqueous solubility, which can be controlled by its inclusion complexes with native or chemically-modified cyclodextrins. In this work, the temperature-dependent … Nettet21. mar. 2024 · Hence chlorine has the highest value of negative electron gain enthalpy among all of these. Note: The point of confusion in this problem can be the order of … base ubuntu install
