Use the heisenberg uncertainty principle to calculate the uncertainity in meters in the position of 0.68g and traveling at a velocity of 0.85 m/s. assume the uncertainity in meters in the position of a helium atom if the uncertaunty in the velocity is 0.1 m/s

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.

Which buffer would be better able to hold a steady ph on the addition of strong acid, buffer 1 or buffer 2? explain. buffer 1: a solution containing 0.10 m nh4cl and 1 m nh3. buffer 2: a solution containing 1 m nh4cl and 0.10 m nh3

Once similarity and one difference between a mixture of elements and a mixture of compounds
