i saw program in national geographic "Naked Science : Explosive force" they took the viewers into a secret lab where they showed antimatter of a size of a visible pellet in red colour.it was suspended in air if it touches a matter it will form pure energy .is it true? if so where is that lab? and can any one give details about the lab and antimatter?

I was reading an article in Scientific American about he theory of Dark Energy. In the computer models that were generated regarding the impact of dark energy on galaxy formation and structure, they show what looks like a 3-d cobweb of energy streams flowing from point to point. I guess I don’t have a question but more of an observation I am hoping you can build on. Could it be possible that black holes as we know them are not an extreme gravitational force as opposed to a plasma energy conduit that takes in regular energy and converts it to dark energy which then flows along a preformed plasma path to the next, etc. So the black holes are actually the nexus for dark energy stream intersections. Perhaps the bending of light and appearance of gravity having this effect is an optical illusion created by dark energy plasma.

I said before that I'm developping a new theory that could explains the origin of the univers, the solar system, life in Earth, behaivor aof living beings, a new explanation of the elements and their periodicity, this theory could complete the work of important physicians like prof. Leonard Suskind, prof. Felix Broch, etc.
What I'm looking for is for

A 0.4505 g sample of CaCO3 was dissolved in a small amount of concentrated HCl and the resulting solution diluted to 250.0 ml. A 25.00ml sample of the solution required 24.25 ml of an EDTA(2-) solution for titration.
1) How many moles of CaCO3 were used?
2) What is the concentration of Ca2+ in the 250.0ml of CaCl2 solution?
3) How many moles of Ca2+ are contained in a 25.00 ml sample?
4) How many moles of EDTA are contained in the 24.25 ml used for titration?
5) What is the concentration of the EDTA solution?

A 42 gram block of an unknown metal at 94.0oC was dropped into an insulated flask containing approximately 30.0 grams of ice and 25.0 grams of water at 0oC. After the system had reached a steady temperature it was determined that 9.0 grams of ice had melted. What is the specific heat of the metal? The heat of fusion of ice is equal to 333 J/g.

I recently skimmed a story on Yahoo! front page on a theory that the moon may crumble and disengrate, if that happened what impact would it have on the earth? I know that the ocean's tides would be altered, then what? I am just curious. Serious or thoughtful answers only.

properties of a parallelogram :

(i) opposite sides are parallel and congruent.

what does congruent means here ?

when we say angles are congruent , it means measures are same.

sides are congruent ? what it means ? does it wants to say "lengths" are same ?
