State what you would expect to happen to the cell potential when the following changes are made to the corresponding cells. Confirm your prediction by using the Nernst equation in each case. (a) The pressure of hydrogen in the left-hand compartment is increased.
(b) The concentration of HCl is increased.
(c) Acid is added to both compartments.
(d) Acid is added to the right-hand compartment.
(e) The molar concentration of silver nitrate in the left-hand compartment is increased.
(f) The pH of the right-hand compartment is decreased.

An aqueous solution of hydroiodic acid is standardized by titration with a 0.186 m solution of calcium hydroxide. if 26.5 ml of base are required to neutralize 20.3 ml of the acid, what is the molarity of the hydroiodic acid solution? m hydroiodic acid

What three things determine the shape and size of a puddle when water is poured out onto a surface

The last few miles of the marathon are the most difficult for heather, her hair plastered to her head, sweat clinging to her arms, and her legs already feeling as if they had nothing left, just dead weight. after grabbing a cup of ice water, she feels the ice cubes smash against her nose as she gulps some cool refreshment and keeps on running. in these last few miles, the breeze kicks up and she finally feels some coolness against her skin. drips of sweat, once clinging to her forehead, now spill down, and heather feels more pain as the sweat flows into her eyes.which of the following is the most likely reason why the ice struck heather’s nose when she took a drink? a) water can function as a solvent. b) water can store large amounts of heat. c) water can moderate temperatures through evaporative cooling. d) the density of water decreases when it freezes. e) water has a cohesive nature.sweat remained on heather’s forehead and arms because of the a) high salt content of sweat b) cohesive nature of water c) ability of water to moderate heat d) high evaporative cooling effect of water e) ability of water to act as a solvent
