Why does it seem that resonce has larger infulence than oppostion while both represent case of encountering each other - and you may say that every resonance(when they encounter) is oppsition. So what is the big deal of resonance ?

have passed since humanity began counting time? What do you think? I don't know the exact answer either, just want to know what do you think.

There are 3 dimention of space as far as we are aware of.

There maybe 5 perhaps 6 more spacial dimensions that we cannot see as dictated by string theory/M theory.

So why only one time dimension??

If time is quantized, it must move through some kind of a field right?

Do they know what this field is?

In all types of media coverage, Buzz Aldrin is interviewed, featured, mentioned etc much more than Neil Armstrong. Armstrong was the first man on the moon, however Aldrin is used and gets much more airplay than Armstrong. In fact I can not find much about Armstrong on line. If you believe you can shed some light on this please do.

Comment briefly on the relative values of ∆G standard of the dissociation reaction and the ∆Gf standard of ammonium carbamate in relation to the ‘thermal stability’ of the substance.

∆G standard = 20.01293819 kJ mol-1

∆Gf standard = 446.0129382 kJ mol-1

What do these values mean please?

If cocaine is like ritalin and caffeine, only stronger, and ritalin and caffeine can be used to treat ADD and ADHD...Could cocaine theoretically be used as ADD/ADHD medication?
I'll stress this question is asked purely out of curiosity.

People have theories that the universe is a massive sphere shape. although practically impossible, lets say we could travel long and fast enough (and could live long enough) to travel upward through this sphere, and we managed to get outside the sphere.. then what's there?

Nothingness?
i don't believe that because nothing is something, blackness is something, no air is something.

If the universe ends with a 'wall' or 'force field' then what's on the other side of the wall/force field?

If the edge of the universe is some form of mirror image reflecting the universes own universe.. (slightly confusing myself) then we would have to be able to travel into the reflection, and then once we get into the end of that reflection.. another reflection?? but all of this would be taking up space wouldn't it? so whats on the outer of these reflections?

I think it would have to be something science can't explain.
Any ideas?

we did an experiment in our chem lab wherein we added grinded soda-lime and blended mongo and then heated it. We put moistened litmus paper at a tip of a stirring rod and it turned blue. The questions on our manual are confusing and i'm really having a hard time i need your help...

these are the questions:

1. What is the role of soda-lime in the reaction?

2. Write the chemical equations involved in:
a) reaction with soda-lime
b) reaction with litmus papers

3. why is the soda-lime test NOT considered a confirmatory test for the presence of nitrogen?

please.. i need infos.. i'm really confused.. >.<
thanks!

......positive terms. If (the summation from n=1 to infinity) of a_n is convergent, then (the summation from n=1 to infinity) of [sqrt(a_n)/n] is convergent.

Thanks!

Procedure:

Obtain a piece of copper wire. Note the color of the wire and record your observation. Make a loop at one end of the wire and eat it to red hot. Allow it to cool and note the change in color of the wire.

Dip the heated copper wire in METHYLENE CHLORIDE Solution. Heat the loop and note the color imparted to the flame.

Reapeat the procedure using IODOFORM.

Results:
Both copper wires produced a green flame.

So, here are my questions:
1. What is the role of the heated copper wire in the reaction?
2. Is the beilstein test a conclusive test for a particular halogen? Why/not?
3. Give the principle involved in this test.

P.S. Thank you for those people who wouldn't flame this....
