Does carbonate have calcium carbonate in it?
No. The carbonate ion contains only carbon and oxygen. Since it is a negative ion, it must combine with some positive ion. If that positive ion is calcium, you get calcium carbonate.
Is calcium carbonate element or compound explain?
Compound. Elements only have one kind of atom. Calcium carbonate has 3- calcium, carbon and oxygen. CaCO3
How would you know the Normality of HCL?
This can only be established by accurate standard titration with sodium carbonate (p.a.)
What makes up calcium hydrogen carbonate?
The chemical formula of calcium hydrogen carbonate is Ca(HCO3)2; this compound (which contain calcium, carbon and hydrogen) exist only in water solution.
Is calcium carbonite bad?
In humans, calcium carbonate is only harmful if ingested in abnormally large quantities.
Why calcium carbonate is not part of organic chemistry?
It is only a traditional nomenclature.
Why is it important to add sodium chloridne to water when making homemade ice cream?
If you add calcium carbonate to 100g of water at 25oC, only 0.0014g of it will dissolve. Additional calcium carbonate will not dissolve.
How many moles are there in 200 grams of Calcium Carbonate?
For a partly ionically bonded compound such as calcium carbonate, the gram formula mass is substituted for a mole, which technically exists only for purely covalently bonded compounds. The gram formula mass for calcium carbonate is 100.09. Therefore, 200 grams constitutes 200/100.09 or 2.00 gram formula masses of calcium carbonate, to the justified number of significant digits.
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 calcium carbon oxygen?
There is no compound CaCO. Since carbon and oxygen are non-metals, the only compounds they are likely to form with calcium are ionic compounds. So that would require making an anion out of carbon and oxygen. The only polyatomic anion that you can get from carbon and oxygen is carbonate, CO32-. So the calcium carbon oxygen that you might be referring to is calcium carbonate, CaCO3.
Why might you expect magnesium carbonate to behave in a similar way to calcium carbonate?
They are both group 2 elements, separated by only one period.
Can calcium carbonate be aqueous?
It can... but only briefly, and it requires a tremendous amount of heat. For example, calcite (the most stable form of calcium carbonate, CaCO3) melts at 2442° F and vaporizes soon after, converting itself into carbon dioxide (CO2) and calcium oxide (CaO).
