You are in charge of a plant that makes methyl bromide, CH3Br. This compound is used as a fumigant for nematodes. The thermochemical equation for the reaction is:
CH3OH(aq) + Br−(aq) equilibrium reaction arrow CH3Br(aq) + OH −(aq) ΔH = +78 kJ/mol.

You must maximize the yield of the product. Which of the following actions should you take? (Select all that apply.)
run the reaction with excess Br− ion
allow excess CH3Br to build up in the reaction
remove Br− ion
remove CH3OH
remove CH3Br as it is formed
heat the reaction
run the reaction with excess CH3OH
cool the reaction

explanation:

2b2t

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.
