From the ones that you are showing me the more positive the potential the more likely: 

Fe+3 + e- ---> Fe+2
I hope this is something very useful

the right answer is d. Na+ + e- Na = -2.71 V

i think, i had trouble finding this one...

Indicate whether each of the following compounds will gave an acidic, basic or neutral solution when dissolved in water. Clear A

allsm [11]

Answer: ammonium bromide : acidic : The pH will be less than 7.

potassium cyanide : basic :The pH will be more than 7.

calcium nitrate: neutral : The pH will be approximately equal to 7.

calcium hypochlorite : basic :The pH will be more than 7.

Explanation:

pH is defined as the negative logarithm of hydrogen ion concentration. The scale ranges from 0 to 14.

When a solution is acidic, it will show a pH in the range of 0 - 6.9. When a solution is basic, it will show a pH in the range of 7.1 - 14. When a solution is neutral, it will show a pH of 7.

ammonium bromide : $NH_4Br$ : acidic as it is formed from the combination of strong acid HBr and weak base $NH_4OH$

potassium cyanide : $KCN$ : basic, as it is formed from the combination of weak acid HCN and strong base KOH

calcium nitrate: $Ca(NO_3)_2$ : neutral, as it is formed from the combination of strong acid and strong base.

calcium hypochlorite : $Ca(ClO)_2$ : basic, as it is formed from the combination of weak acid $HOCl$ and strong base $Ca(OH)_2$

In which organ in a earthworm can I find the content to be most ground up and why

Yanka [14]

The intestines

By the time food has reached the intestines, it has already passed through the gizzard (where it is ground up) and has nutritious pieces absorbed before waste is passed to the excretory system.
