I need to write the half equation for the S2O32-/S4O62- redox couple but I'm having trouble because they have the same ioic value.
I've come up wth two solutions but am happy with nether...
S2O32- + 3H2O + S2= S4O62- + 6H+ + 6e-
or
2S2O32- = S4O62- + 2e-
I know that the second one...
it does make sense, but I don't know how to do that... or is that what I've done?
Is the Vled value there just as extra information that isn't needed or?!?...
Calculate the value of the resistor using the following information:
Vs=9volts, Vled=3volts, and Iled=10mA
I'm assuming that it's just Ohm's Law R=V/I,
but I don't know which of the two voltages I use, though I think its the Vs...but I don't know what the 's' stands for either.
this...
i need to know the formula for calculating the uncertainty of a gradient from a graph. the gradient is being used to calculate the moment of inertia but i can't calculate the error in my I cause i don't know how to calculate the error in my M!
when i did the experiment, i assumed the error to...
Not cynical at all are you?!?
wouldn't call myself a kid, (24 - I know, how ancient!)
but definitely asking for help with bio assignment, is very late and still no clue... have sadly run out of coffee... woe is me :(
personally have no time for creationists - twats don't think animals...
the source is a Biology assignment, and the question is "In 1859, Charles Darwin published Thw Origin Of Species in which he presented ideas on the causes of organismic change through time.
A primary conceptual gap existed which left his theory open to criticism. What was that conceptual gap?"...
