In order to complete his research project, Roger needs to make a mixture of 86 mL of a 36% acid solution from a 39% solution and a 17% acid solution. Find the volume of the 39% acid solution that Roger needs to use to make the mixture.

answer: you could do some invislibe ink.

explanation: i will tell you how to if u answer my question.

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.
