The world is like an atom. The not-quite-as-intelligent people are the nucleus all packed together sharing a common...everything. We, we are the electrons. Granted we're not as smart as these engineers and what-not so we're most likely in the first orbital, but we're the electrons of this giant atom. We all have differing intelligences and ideas and we are separated from the nucleus which makes us better because no one really cares about how a nucleus acts. It's the electrons that make chemistry, except for nuclear chem, of course, which I am a big fan of.

hey guys have any of you figured out why number 55 on the 02 test is first order.

here is the question

Time (days)   0     1   2   3   4  5   6   7  10  20
%Reactant    100 79 63 50 40 31 25 20 10   1
Remaining

we know the half life is 3 days but why is it first order?

i thought it first because it progresses at a constant 3 days instead of 3-9-27. that is probably wrong but it got the right answer.

close, tyler don't look yet if you haven't done it







the equation is set up as -.14 - x = .60, solve for x which comes out to...

well in circuits, which way do electrons flow? from - (cathode) to + (anode) or opposite.

and note the reply to matt for the other

didn't tesdahl say that the e- flow opposite of current which means they go from anode to cathode right?
