Why are a variety of instruments needed to measure change in the climate system?
a.
a different type of instrument is needed for each different climate.
b.
the climate system involves a number of different factors that are measured differently.
c.
climate is determined over a number of years, rather than a short period of time.
d.
different areas have developed different instruments to measure climate change.

The density would be 1.622

Decomposition is the cycle at which bacteria breaks down any organic material into the soil

Answerthe half-reaction having the greatest tendency to occur at the anode:     i₂(aq) + 2e⁻  ⇄ 2i⁻  ;   e = +0.53 v======oxidation occurs at the anode. we must therefore find the half-reaction with the greatest tendency to oxidize.the given values of e are reduction potentials (the form of the half-reactions are of reduction).the lower the reduction potential, the higher the potential to oxidize. the half-cell with the lowest reduction potential will have the greatest tendency to oxidize at the anode.the half-reaction having the greatest tendency must be    i₂(aq) + 2e⁻  ⇄ 2i⁻    e = +0.53 vbecause its reduction potential is the lowest out of the three.
