What is the main constituent of a Pearl?
Pearl is made up of calcium carbonate, which has the formula CaCO3.
What is inside calcium carbonate?
CaCO3 + H2CO3(aq) -> CaCO3 + H2CO3(aq) There is nothing to drive any sort of reaction at conditions near STP. At elevated temperatures such as would be found in a cement kiln, the calcium carbonate would decompose to calcium oxide and carbon dioxide while the carbonic acid would have long since evaporated to give water vapor and carbon dioxide.
Is calcium caltrate the same as calcium?
No the chloride ion is a chlorine atom that has gained an electron and has a -1 charge. Because it is charged the chloride ion must be accompanied by a positive ion of some sort to balance the charge. Calcium chloride is a compound that contains chloride ions (Cl-) and calcium ions (Ca2+) and has the formula CaCl2
What form is lithium carbonate?
A powdery sort of thing, like flour
What is the colourless gas having suffocating smell dissolves in lime water?
The answer is Carbon Dioxide (CO2). I assume this is what you mean - Carbon Dioxide is the waste product of respiration that can suffocate some animals, including humans. It is used by plants in photosynthesis, and these plants produce Oxygen (O2). It reacts with lime water and turns it a sort of milky colour. The equation for this reaction is Carbon Dioxide (CO2) + Calcium Hydroxide (Ca(OH)2) ---> Calcium Carbonate (CaCO3) + Water (H2O)
What do antacids contain?
Most antacids contain oxygen and some sort of metal (calcium, sodium, potassium, aluminum, and magnesium are common). Additionally, most will contain hydrogen (in Mg(OH)2 and Al(OH)3), carbon (in CaCO3), or both (in NaHCO3 and KHCO3).
Why can calcium hydroxide be used to test for carbon dioxide?
I have just answered this question as part of homework myself, limewater is a common name for Ca(OH)2 (calcium hydroxide) and when limewater and carbon dioxide meet they instantly react in a visible way. The limewater turns cloudy, sort of like when milk and water meet. Hope this helps

What is calcium carbonite?
There is no such thing as calcium carbonite. It is likely a typo or a misspelling. However, calcium carbonate is a common compound found in rocks, shells, and pearls, and is often used as a dietary supplement for calcium.
What is the chemical formula for antacid?
The chemical formula for antacids can vary depending on the specific type, but common active ingredients include calcium carbonate (CaCO3), magnesium hydroxide (Mg(OH)2), and aluminum hydroxide (Al(OH)3). So, technically speaking, there isn't just one chemical formula for antacids. It's like asking for the recipe for a fruit salad without specifying which fruits you're using.
Why is calcium carbonate insoluable?
It is a very good question indeed! You see calcium chloride in which calcium is attached to two chlorine atoms is water soluble and vice versa sodium carbonate in which two sodium atoms are attached to one carbonate is soluble. In one to one proportion, calcium chloride molecule is insoluble. Now the answer for this question may go like this. In case of calcium chloride calcium gives one electron to each of chlorine atom. Now both chlorine atoms would have one negative charge. So both of them will repel each other and form the ions of calcium and two chlorine. Thus making them soluble. In case of sodium carbonate, two sodium atoms give electrons to carbonate. Now both sodium ions become positively charged and and would repel each other. So they would form ions along with carbonate. So sodium carbonate has become soluble. Now in case of calcium carbonate, calcium would like to give away 2 electrons but carbon becomes much electrically negative if it takes the electrons. So in this case no repelling force is there to help the metal, it surrenders and form sort of covalent bond and thus ions are not formed. So calcium carbonate is insoluble in water.
What sort of chemicals are statins?
they are hydrocormick-clarc chemicals
What chemicals do antacid contain?
The main reactive chemicals are magnesium carbonate and/or magnesium hydroxide. Both react with excess stomach acid, to neutralise the acid. Excess stomach acid is evidenced by 'reflux'(heart burn), where the contents of the stomach momentarily bubble up to the throat. The stomach normally digests food in a pH evironment of '1'(one). This occurs naturally by the stomach walls secreting hydrochloric acid (HCl) into the stomach. That horrible burning sensation on reflux is the hydrochloric acid. So the reaction schemes to settlethe stomach are MgCO3 + 2HCl = MgCl2 + H2O + CO2 (burp!!!!) Mg(OH)2 + 2HCl = MgCl2 + 2H2O Notice in both cases the salt magnesium chloride is produced and water. Hence dlluting the stomach contents. Eating too much food and particularly fatty food, makes the stomach work harder, to produce more hydrochloric acid, hence with an overful stomach you may suffer with reflux. Eating acidic fruit , oranges, apples strawberries etc., aids the digestion by supplementing the hydrochloric acid content; 'common ion effect'.

What type of matter is chalk?
Chalk is a solid. But obviousley when it is like, well, rubbed i guess you could say it because a sort of gas type thing. the second sentence above is wrong.footnote. Chalk was the name given to the immense deposits of the calcium carbonate remains of tiny sea animals.The schoolroom chalk is usually made from a base of calcium sulphate (gypsum).
