Which of the following statements is correct? a) The reaction is always spontaneous at all conditions. b) The reaction is always nonspontaneous at all conditions. c) Kp for this reaction is less than 1.0 at 298K. d) The reaction could be non spontaneous at very high partial pressures of NO2 (g) and O2 (g). e) The reaction could be non spontaneous at very high partial pressures of N2O5 (g).

What effect might melting sea ice have for people who live in coastal areas?

How have the greenhouse gasses increased from the year 2000 to 2018

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
