How is ∆Hfusion used to calculate the energy needed to melt the mass of a solid

When svante arrhenius first proposed his acid-base theory, he was a doctoral candidate. his professors thought his ideas were unfounded. within a decade, the arrhenius theory of acid-base was widely accepted and praised within the scientific world. arrhenius defined acids as compounds having ionizable hydrogen and bases as compounds with ionizable a) barium. b) hydronium. c) hydroxide. d) oxygen.

Consider the elements bromine and chlorine; which elements has a larger ionic radius ?

How does the presence of oxygen affect the chemical pathways used to extract energy from glucose?
