One way the u. s. environmental protection agency (epa) tests for chloride contaminants in water is by titrating a sample of silver nitrate solution. any chloride anions in solution will combine with the silver cations to produce bright white silver chloride precipitate. suppose an epa chemist tests a sample of groundwater known to be contaminated with copper(ii) chloride, which would react with silver nitrate solution like this: (aq) (aq) (s) (aq) the chemist adds m silver nitrate solution to the sample until silver chloride stops forming. he then washes, dries, and weighs the precipitate. he finds he has collected of silver chloride. calculate the concentration of copper(ii) chloride contaminant in the original groundwater sample. be sure your answer has the correct number of significant digits.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?

answer; 4 electrons;
