Some scientists want to create a new kind of liquid. One liquid contains 8% sodium (Na) and the other liquid contains 15% sodium (Na). Once they mix the two liquids the resulting chemical contains 11% sodium (Na). How many milliliters (ml) of each liquid must be mixed to obtain 300 ml of the new liquid?

If Evolution is so true how can you have nothing and get something? Also, if animals evolved then how did such animals like aracnids ( Like the funnel spider, or black widow), venomous frogs and snakes become equipped with neuro-toxinous venom? It doesnt seem probable that natural selection nor evolution could provide such complex creations with such a defense mechanism? So if the animal evolved, how did its toxin?

nanometers. By additive color theory, the three primary colors are green, blue, and red. If you understand the math behind the way light of different wavelengths interact, for example red and green light seen together are perceived as yellow, feel free to respond to this question. Thanks

This is incredible to think that in 2006 some people think that half of the moon is always lit.... You simply just failed in Astronomy....
And for those who think that I am far gone.... Please make your own observations.... You will understand that the present moonlight theory is totally FALSE... It seems good when in nightime e in DAYTIME the WHOLE present scientific theory cannot be right......... SORRY for the unknowledgeable people. I STILL DARE THE REAL SCIENTISTS HERE TO ANSWER THIS....

I have 2-3 plants in a large 24" pot. Plants have 1-2 flowers year round. However, flowers do not fully open or open in a non-symetrical shape and they look sick. I water weekly with some light fertilizer. It is in good indirect light and always inside. I replaced soil and it helped it a bid. But it is still sick.
Will appreciate any help.
Thanks. Hmm97

The heat of fusion of water is 80 cal/g, the heat of vaporization of water is 540 cal/g, the specific heat of ice is 0.48 cal/deg/g, the specific heat of steam is 0.48 cal/deg/g and the specific heat of liquid water is 1.0 cal/deg/g. How much heat would be needed to convert 21.07 g of ice at -44 degrees C to steam at 141 degrees C.

I don't believe it at all. It's just too big to be occupied only by a single race of 'intelligent' beings like ourselves, especially considering humans on Earth have only been around for a few million years, and the universe is so much older.
