On a number of occasions I have seen this all white, very large (twice the size of normal one), butterfly around the tropical dry forests on the Oaxacan Pacific coastal plain in Mexico I can't find it on websites. It's so large it looks unreal when it flies, like it's attached to strings. Can anyone help?

Example: Fish sometimes die if the water is still. If agitated, they thrive. So, "H2O is combined to make water. When you agitate water it adds O. I understand if the O were to combine with the H2O, it would become hydrogen peroxide, Ques: If so, why does it not combine?

From a stereochemistry standpoint - what is the shape of an aramid? is there a "general" 3-D shape for the family?

----

Note - i'm not asking for the chemical formula, or even the diagram - i am talking structure, here....3-D structure at the molecular level.

Thanks.

the system:

y = cos x
y = e^x
y = 0.5x + 3

I understand that cos x and e^x are both 1 when x=0. So,

f(x)=cos x for x<=0
e^x for 0
But I don't understand where to go from there. I know that if I set e^x = 0.5x + 3 I have to use ln but I don't know how nore do I understand it. Can somebody please help explain what I have to do?

For the gaseous reaction of xenon and fluorine to form xenon hexaflouride:

Calculate ΔS° at 298 K (ΔH = -402.0 kJ/mol and ΔG° = -280.0 kJ/mol).
-and-
Assuming ΔS° and ΔH change little with temperature, calculate ΔG° at 783.0 K.

Thanks so much for the help... allnighters are killing me for finals! ><

I heard a scientist say that we could temporarily stop global warming immediately if we shoot dust into the atmosphere. He said that the eruption of Mt. Pinatubo on 1991 placed a lot of dust in the air, which partially blocked out the sun over a large area, which in turn caused the average temperature of the earth to cool by about 1 degree Celsius. I think that this is a great idea. We could use a water soluble dust so that asthmatics will not be affected as badly. The dust will settle within a year, so there is no risk of permanent effects. We could keep doing this as often as needed until we choose to stop emitting greenhouse gases. The dust could be shot into the upper atmoshpere with a specially made cannon, or perhaps a rocket that explodes at the proper altitude. I think that we urgently need to pursue this idea, as the effects of global warming are alarming.
