	Which will freeze faster, hot water or cold water? (water, freezing)
	Is H2O hard to make? If so, why is water hard to come by in some countries? (water, making)
	Why is it important to be able to separate water? The project comes from the Nicholson/Carliasle experiment where, by using a battery hooked up with wire to metal rods in water, they found that gas bubbles would be released. This led, apparently, to electroplating. Why did they think to try this and for what were they looking? Is there anything else you can tell us? (water separation)
	Explain the process of water purification step by step.
	Since the elements of water are H2O is it possible to make a filter that is able to filter out the H2 part and only leave the oxygen part, so that we could breathe under water? If it is possible, can you send me the formula to make such a filter? (H2O filter)
	Why do you get a ring when you put a glass of water on a table? (condensation)
	What happens to the boiling point of water when it is mixed with antifreeze?
	When you get out of the tub, why do you sometimes see steam coming from your body?
	Does putting salt in water speed up or slow down the boiling process? (water, salt, boiling)
	Does an octane booster really speed up hydrocarbon combustion?
	Why is ignition quality important?
	Why is hydrogen the first element?

	What is the preservative in the Hostess Twinkie? Is it true that ingesting large amounts of it (and I don't mean eating more twinkies) would make our internal organs last longer?

	How does volume work?
	Yellow Dye #5 -- What is it?
	How do you make liquids?
	Our project deals with hot and cold and the chemical reaction, such as when kernels of popcorn are placed in the freezer vs. those kernels at room temp. Which will pop faster? That is our question in the experiment. Can you comment on the "why" of this?
	What is the strongest metal?
	Who made the first synthetic diamond?
	Why are pyridine and nicotine toxic?
	Why is curare toxic?
	What is Arsenic?
	What is the primary ingredient of Fire Ant toxin?
	My question is about radiation as a mutagen - how does it "poison" or mutate the cell?
	Why is carbon monoxide so dangerous to humans?
	For a school project, I am supposed to find out if it is possible to make solid oxygen, if so, could you tell me a little about it's temperature and the pressure it takes to make it?
	If oxygen is released in space, what will it look like? Will it bubble like under water? Will it be visible at all?
	I was explaining to some elementary school children that burning was combining with oxygen and also that rusting was combining with oxygen. This led us to wondering two things: If we pour some iron filings into water and they rust will: 1) The water temperature go up? AND 2) Hydrogen be released? (On the assumption that the oxygen came from the water.) If these effects are measurable then they might make a nice science project/demo.
	My fifth grade daughter is learning about chemistry, and asked me are there any circumstances in which oxygen could bond to 3 hydrogen atoms to create H30. If it is possible for this to happen, she wants to write about it for the Science Fair.
	If potassium is mixed with water, would there be a reaction? If so, what would the reaction be and why?
	Is it possible to change smoke into a solid?
	I am curious as to what the mechanism is, that accounts for the fading of some colors in sunlight. For that matter, what accounts for some colors to be reflected, and others to be absorbed.With the above in mind, how is it possible, that some materials or dyes are far more resistant to fading.
	Interested in new ideas on the kinetic mechanism of crystal growth and dissolution of inorganic minerals i.e. calcium carbonate , barium sulfate, silica etc. and where such advances can be applied to new and improved commercial products.
	I've read that brewed tea tastes better if you use cold water that was heated just short of boiling. The theory is that if you boil it, the oxygen will be somehow bubbled out. QUESTION? If the chemical formula for water is H2O, do you end up with a cup of "H" ? What oxygen is boiling out? Where does the oxygen come from to boil out? Subquestion: they recommend cold water to avoid using the water that has been sitting in the water heater "losing oxygen." Again, would you kindly explain the process? Second subquestion: I know that if the surface area of an aquarium is not large enough with respect to the size of the tank, you must use an air pump to add oxygen to the water. Does the chemical formula change? Is there "oxygenated water?" I don't imagine it's "heavy water," so what is it?
