Determine the solubility of n2 in water exposed to air at 25°c if the atmospheric pressure is 1.2 atm.

assume that the mole fraction of nitrogen is 0.78 in air and the henry's law constant for nitrogen in water at this temperature is 6.1 × 10-4 m/atm.

The characteristics of two different types of reactions are shown below: reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.
