Its possible, in fact its long overdue! Evolution cannot re-create human life as we know it today. The only way is by creating mutants which can take care of each other rather than destroy each other. What are yor views on this matter?

Now, I've been thinking (I sometimes do that ya' know!): I mean, gee whiz, when those ballerinas pull their arms in, they really spin like crazy! So if we'd just sit our fat rear ends down (and stop hangin' out at the door waiting for quitting time), wouldn't time fly by so we could go home sooner? (Ouch, I just bit my tongue and cheek!)

1. C2H4(g)+3O2(g)-->
2CO2(g)+2H2O(l) deltaH= -1411kJ

2. C(graphite)+3H2(g)+(1/2)O2(g)-->
C2H5O2 deltaH= -278 kJ

3. C2H4(g)+H2O(l)-->
C2H5OH(l) deltaH= -44 kJ

final: C2H5OH(l)+3O2(g)-->
3H2O(l)+2CO2(g)

I can't figure out how to cancel the second equation because there is a single C and H2 there.Can anyone explains please?step by step solution please.Thank you.

What if the Bible is just a book that someone wrote? Is there life on other planets? If there is, is it just like here. What if theres like more than the... 9 planets or whatever?? I'm so confused!! I really wanna know!!

I know no one really knows. But what do you think and why?

seems like they could be used for something, maybe burned as a fuel source! Can they be eaten by humans, cooked or something. I have raked up wheelbarrows full of them, and it seems like they should have some purpose besides feeding squirrels and denting my car. ANyone know anything about acorns??
