A solution of a metal carbonate, M2CO3 was prepared by dissolving 7.46g of the anhydrous solid in water to give 1000 cm3 of solution. 25 cm3 of this solution reacted with 27 cm3 of 0.100M hydrochoric acid. Calculate the relative formula mass of M2CO3 and hence the relative atomic mass of the metal M.

Obviously, I know to be successful you need both, but I LOVE math, so I'm trying to see which one I should do more research on.

A 1.575g of a sample of ethanedioic acid crystals, H2C2O4.nH2O, was dissolved in water and made up to 250 cm3. One mole of the acid reacts with two moles of NaOH. In a titration, 25cm3 of this solution of acid reacted with exactly 15.6cm3 of 0.16M of NaOH. Calculate the vaue of n

I am looking for an insect, well actually two.
Both of these insects actually have 4 eyes. If this doesn't seem odd to you, well the majority of insects have two large compound eyes and usually three ocelli or simple eyes. Some orders like Diplura and Protura dont have eyes at all.

The insect I am looking for is a member of the order Coleoptera, it has four seperate eyes and they all function independantly. If you can give me its common or latin name and one adaptive advantage of this peculiar eye arrangement you will get the points......first one to give the best answer wins (no copy and paste).
However, as I mentioned at the beginning, there are two commonly known species with 4 eyes, The reason for the second species having 4 eyes is still not clearly understood, but if someone could provide both species, the points go to them......

good luck!

e^(pi*i)=-1 using calculus we know this is true but square both sides and you get:
e^(2pi*i)=1 which is also true but if you natural log both sides you get:
2pi*i=ln1 which is obviously false since ln 1 is real
why can't you natural log e^(2pi*i)?
