Astudent develops the list shown below that includes laboratory equipment and materials for constructing a voltaic cell.
laboratory equipment and materials
• a strip of zinc
• a strip of copper
• a 250-ml beaker containing 150 ml of 0.1 m zinc nitrate
• a 250-ml beaker containing 150 ml of 0.1 m copper(ii) nitrate
• wires
• a voltmeter
• a switch
• a salt bridge
complete and balance the half-reaction equation in your answer booklet for the oxidation of the zn(s) that occurs in the voltaic cell. [1]

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:

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.
