Consider the process a(l) → a(g) 73°c 161°c, which is carried out at constant pressure. the total δs for this process is known to be 75.0 j·k−1·mol−1. for a(l) and a(g), the cp values are 75.0 j·k−1·mol−1 and 29.0 j·k−1·mol−1, respectively, and are not dependent on temperature. calculate δhvaporization for a(l) at 125°c (its boiling point).

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.

Compare and contrast physical changes with chemical changes.

Given that 1 mi = 1760 yd, determine what conver- sion factor is appropriate to convert 1849 yd to miles; to convert 2.781 mi to yards.
