I'm toying around with electrolysis and it destroys EVERYTHING. I got my hands on some platinum wire, but now I need to know what I can used to coat the non-platinum wire that connects to the platinum electrodes. I'd rather not reinvent the wheel.

Thanks!

The human body is full of electrical energy and atomic energy. The laws of Conservation and Mass state that energy cannot just disappear it has to go somewhere. So when we die where does that energy that our body produces go? Is that energy really our soul, is that what makes us think and feel. Where do you think our energy is conserved, where does it go, and do you think that our souls are that energy and we stay with it after death...

is methane heavier or lighter than air? is it still gas at room tempurature? can you fill a normal balloon with it, and if so, what would would be the range of damage of lighting it on fire (with a fuse of course)

More diffusion in liquids than solids due to two factors.
1.greater intermolecular distances 2.great random motion.
when water freezes to give ice the intermolecular distances increases batween water molecules but the diffusion is still less than liquids why?
Some might think that diffusion only depends on random motion of molecules not inter molecular distances how do they justify their answer?

and
at STP distance between the melecules of an ideal gas is three hundered times greater than its diameter.(how its possible)
suppose diameter of h2 melecule is 2nm and two melecules are at a distance of 600nm.And diameter of CO melecule is 4nm(or take any other molecule larger in size than that of h2)and the distance between its two melecules will be 1200nm
so two melecules at STP are not occupying same volume.
if they have to occupy the same volume then CO molecules would have to come closer.
and if they come closer then distance between them will be not 300 times greater than their diameter.
if m wrong then how?

Consider the titration of a solution of TtRd with the titrant TrNt which proceeds according to the following analytical reaction:

2TrNt + 3TtRd 5PrOd + 2H2O

The equation describing the quantitative relationship between the weight (mass) of TtRd and the concentration of TrNt which applies at the equivalence point of this titration has the following form:

MTrNt x VTrNt = (WtTtRd / Molar MassTtRd) x Stoichiometric Ratio

What is the numerical value of the Stoichiometric Ratio? Express your answer to four significant figures.
NOTE: Since stoichiometric coefficients have unlimited precision, so will the stoichiometric ratio. You are being asked to use four significant figures only out of convenience. Also, give some careful thought on your own to the units which the stoichiometric ratio should have.
