Calcium hydroxide is an ionically bonded compound that dissolves in water to form a strong alkali; calcium carbonate is an ionically bonded compound that dissolves in water to form a weakly alkaline solution.

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.
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 form is lithium carbonate?
A powdery sort of thing, like flour
Why was the Tollund Man copse so well preserved in the bog?
Because the chemicals in the bog acted as sort of a preservative.
What chemicals do antacid contain?
An antacid usually contains some sort of base. One antacid, milk of magnesia, is magnesium hydroxide. Other antacids include aluminum hydroxide, sodium bicarbonate, and potassium bicarbonate.

Pearl is made up of calcium carbonate, which has the formula CaCO3.
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 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.
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 sort of chemicals are statins?
they are hydrocormick-clarc chemicals

A powdery sort of thing, like flour
What does acid carbonate gives this sort of reaction?
Some thing beginging with E
What is the chemical formula for antacid?
The chemical formula for ingesting antacid tablets is simply a neutralization reaction. It depends on what base the antacid contains, but common reaction would be NaHCO3 + HCl ----> NaCl + H2O + CO2.
Stalactites are deposits hanging from cave roofs caused by draining ground water?
Sort of. The water percolating through the joints in the limestone above the cave, dissolves some of the rock's main chemical, Calcium Carbonate. On emerging through the cave roof, some of the dissolved carbonate is precipitated in its crystalline form, Calcite, very slowly building up the stalactites and stalagmites.
