Consider the half reaction below. Cu + (aq) + 2e
Cuis)
Which statement best describes what is taking place?

Reduction reaction

This is so because considering the reaction Cu 2+ has been reduced to Cu(s) by losing two electrons , and any other element that undergoes this stage is termed as a reduction reaction.

Hope this helps

distance, luminosity, brightness, radius, chemical composition, and temperature

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.
