How process most likely formed these stalactites and stalagmites?
It is known - they are calcite deposits precipitated from soultion in ground-water that dissolved it from the limestone above the cave. The real puzzle is the development of "helictites" - stalactites chemically and in principle, but growing into fantastic shapes like spaghetti, and no one theory fits them all!

Are mirages real?
yes mirages are real
Are dimonds real?
Yes dimonds our real!
Why is there no way to prove if gods real but a way to get to the moon?
Because we know the moon is real, we have the technology to get there, god on the other hand is not real and there is no way to prove that he is real, it's like trying to prove the tooth fairy is real
Why does acid weaken the egg shell?
The real Ugg boots are made out of Australian sheepskin. You can find them in any high end store but do not but them at Wal-Mart because thos are not real. You can also go to their site at http://www.uggaustralia.com/on/demandware.store/Sites-UGG-US-Site/default/Default-Start?source=ggl_ppc&s_kwcid=TC|6895|uggs%20shoesS|e|9106232580&gclid=COba-qrM_KoCFQPrKgodPj9t2A.
What is the real world connection on stalactites?
They exist in the real world: they are physical things.
What liquid can melt a pearl?
Pearls will dissolve in vinegar. This is because pearls are mostly calcium carbonate (you can find calcium carbonate probably in your medicine cabinet--it is the main ingredient in stomach antacid tablets, such as Tums). Another common item that is calcium carbonate would be eggshells. It is just in a harder form.Calcium carbonate, through chemical reactions to a weak acid solution (vinegar, also a red wine would be a weak acid solution), dissolves the chemical bonds in the calcium carbonate pearl and therefore, it will dissolve.Give it a try yourself--get some eggshells, place them in a glass. Then add white vinegar. Give it a bit and see what happens to the eggshell.I would really suggest that you not try this will real pears--real pearls are expensive, and someone would be really, really angry that you destroyed expensive pearls--eggshells are so much better to do this experiment. No one is going to really mind that you have dissolved eggshells
Do antacids have calcium hydroxide in them?
No, some have calcium carbonate or magnesium hydroxide, but not a strong base such as calcium hydroxide. However, medical doctors have prescribed calcium hydroxide as an antacid for severe acid reflux and severe heartburn. Interestingly, when a molecule of calcium hydroxide collides with a molecule of carbon dioxide at room temperature, it readily becomes calcium carbonate plus water: Ca(OH)2 + CO2 → CaCO3 + H2O However, when a solution of calcium hydroxide enters the human stomach, the primary chemical reaction is: Ca(OH)2 + 2HCl → CaCl2 + 2H2O [Calcium hydroxide reacts with hydrochloric acid at room temperature to become calcium chloride plus water]. Calcium hydroxide is water-soluble. Calcium carbonate is not neutral-pH-water-soluble at room temperature. However, calcium carbonate is acidic-water-soluble at room temperature. Because it is relatively harmless, calcium hydroxide is used as a preservative for glucomannan foods such as shirataki noodles and konnyaku cubes. Calcium chloride is also relatively harmless and is used as a preservative in many foods. Although not quite as delicious as real salt, calcium chloride gives foods a salty taste and greatly reduces or completely eliminates the need for sodium chloride in pickles. Calcium carbonate is the best-selling calcium supplement because it has a low price and also because it blocks about 65% to 70% of the absorption of heme iron, a cancer-causing and artery-clogging pro-oxidant. All other forms of calcium supplements can block only about 10% to 20% of the absorption of heme iron. People who swallow 300mg to 600mg of calcium daily as calcium carbonate are about 25% to 30% less likely to develop colorectal cancer than people who swallow other forms of calcium supplements or no calcium supplements at all. Caution: Do not swallow more than 600mg of calcium from calcium supplements daily. Numerous scientific studies now say that people who swallow more than 600mg of calcium from calcium supplements daily are almost twice as likely to die of cardiovascular problems compared to people who don't swallow any calcium supplements. Note: If you already suffer from calcified arteries, then eat a small amount (3oz is more than enough) of the Japanese fermented soybean food called, natto, every day. No other food and no prescription medicine can reverse arterial calcification. About half of all people with cardiovascular disease have calcified aortas when examined by chest X-ray.
How is Calcium used in the real world?
Calcium is used in milk.... although you can get more calcium in a glass of skim milk than when it has fat
Rainwater is weak acid that dissolves limestones and rock and creates caves?
Correct, in limestone including its meta-form marble, and gypsum; respectively calcium carbonate and calcium sulphate. The acidity comes from absorbed atmospheric carbon-dioxide. NB though: Limestone is a rock anyway, but only these two calcium compound rocks are soluble to any real extent. Dolomite (magnesium carbonate based) will dissolve but the physical nature of its deposits tends to prevent cave formation. Rainwater will also attack the felspar in granite but the process, hydrolysis, is extremely slow and does not lead to dissolutional caves in granite.

Should people allergic to shellfish use pearls?
Yes, you can have an "allergy" or in this case (to be more precise) a 'sensitivity' to real pearls (or anything else under the sun).In my experience I have not yet met anyone who is actually allergic to pearls and I have been in the pearl retail/wholesale and pearl farming business for many years. If someone experiences and allergic reaction to a piece of pearl jewelry, the most likely reason will be the finding. People are allergic to different alloys, especially nickel. There are elements of nickel in 14k and 18k gold and people do have a reaction to this. In general, pearls are hypoallergenic. But in case of imitation pearls some people may have an allergic reaction when they come into contact with them.As a jewelry artist who works with variety of media including freshwater and salt water pearls there has never been a client who was allergic to pearls yet. People can be allergic to calcium carbonate, which the pearls are made of. Calcium carbonate, essentially calcium salt, is found in the Calcium supplements that anyone can buy over the counter at any drug or health store. Allergy to Calcium Carbonate is very rare, but it does exist. For the most part people are allergic to Calcium Carbonate when digested. Unlike pearl jewelry, calcium supplements are taken orally. However, humans have a habit of testing authenticity of pearls by running them in between lips or teeth. Existence of pearl allergy seems highly probable.

What real the name of the element CaCl2?
CaCl2 is Calcium Chloride.
How do you grow your Neopets?
You can not grow your neopets because they are not real.
What observations do you make when you react potassium hydroxide with sodium carbonate?
You get a double decomposition reaction, producing sodium hydroxide and potassium carbonate, but actually there is no real reaction; the four substances remain in perfect equilibrium in solution.
