At 400 k, the equilibrium constant for the reaction br2 (g) + cl2 (g) ↔ 2brcl (g) is kp = 7.0. a closed vessel at 400 k is charged with 1.00 atm of br2 (g), 1.00 atm of cl2 (g), and 2.00 atm of brcl (g). use q to determine which of the statements below is true.
(a)-the equilibrium partial pressure of brcl (g) will be greater than 2.00 atm.
(b)-the equilibrium partial pressure of br2 will be greater than 1.00 atm.
(c)-at equilibrium, the total pressure in the vessel will be less than the initial total pressure.
(d)-the reaction will go to completion since there are equal amounts of br2 and cl2.
(e)-the equilibrium partial pressures of br2, cl2, and brcl will be the same as the initial values.

Which formula can be used to calculate the molar mass of hydrogen peroxide

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
