Answer:
Fe
Explanation:
The cell potential is:
ΔE°cell = E°red(red) - E°red(oxid)
Where, E°red(red) is the reduction potential of the substance that is reducing, and E°red(oxid) is the reduction potential of the substance that is oxidizing. For the reaction be spontaneous and happen, ΔE°cell > 0.
The reduction takes place in the cathode, which is the negative pole, and the oxidation in the anode, which is the positive pole. So, the electrons flow from the positive pole to the negative pole (anode to cathode).
Then, if the voltmeter measured a negative potential, it means that is was attached incorrectly. So, the anode is Fe.

The hierarchy of species is mainly used by taxonomist in order to classify, organize and systematize certain species in both the animal and plant kingdom so to speak –living things. These helps them if found a new discovered specie, they cluster it into the appropriate category into where it fits best. There are certain factors to categorize though.
The correct option for above statement is:
B.Joseph Proust
Explanation:
Joseph Proust printed his Law of Definite Proportions (or Law of Constant Composition) in 1794. This law states that a compound consists of exact proportions of parts by mass no matter however the compound was created.
