What is the enthalpy of formation of kbr03?
The enthalpy (heat content) and Gibbs energy (formerly the free energy) of formation of KBr03 when one gram formula weight in the crystalline solid state is formed isothermally at 298.15K (25 °C) is -86.10 kcal/mole and -64.82 kcal/mole, respectively. Weast, R.C. (ed.).
Does diethylmaleate prevent strand breakage by KBRO (3)?
Depletion of intra-cellular GSH by diethylmaleate in human lymphocytes decreased the amount of strand breakage induced by KBrO (3). Extracellular GSH, however, protected against DNA strand breakage by KBrO (3), possibly due to the inability of the reactive product to enter the cell.
