The atomic masses of He and Be are 4.00 and 9.01 amu, respectively. Which of the following statements are true? Group of answer choices A mole of Be contains the same number of atoms as a mole of He. None fo these are correct A mole of Be contains more atoms than a mole of He. A mole of He is heavier than a mole of Be.

the mass of the cathode increases because ions from the solution get reduced to atoms and become part of the cathode.

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.
