C.
Explanation:
Exothermic means the energy of products is lower than energy of reactants. Transition state will always be the highest energy among the two.
The correct answer is: by the transfer of one or more electrons from one atom to another.
Answer:
The concentration is 6.42×10^-4 M
Explanation:
Number of moles trichloroethylene = pressure × volume/Henry's constant = 0.00301×0.21/0.00985 = 0.0642 mol
Volume of mixture = 100 L
Concentration of trichloroethylene = number of moles of trichloroethylene/volume of solution = 0.0642/100 = 6.42×10^-4 M
It is based on Relative DENSITY.............
