What is chemical composition of limestone?
CaCO3--Calcium carbonate--calcium, carbon, oxygen.
Can calcium carbonate reduce acidity?
CO3(2-) This polyatomic ion, released from Ca(2+) in solution, may pick up protons, but I am not sire of a straight neutralization reaction here, though CaCO3 is a weak base. Probably an equilibrium reaction with bicarbonate and carbonic acid here.
When a 1.25-gram sample of limestone was dissolved in acid 0.44 gram of CO2 was generated if the rock contained no carbonate other than CaCO3 what was the percent of CaCO3 by mass in the limestone?
CaCO3 +2HCl ------------> CaCl2 + CO2 + H2O number of moles of CO2 in .44 grams = .44/ 44 = .01 From equation it is clear that 1 mole of CO2 is produced from CaCO3 = 1 mole .01 mole of CO2 is formed from CaCO3 = .01 mole Weight of .01 mole of CaCO3 is = .01mole *100 g/mole = 1 gram weight % of CaCO3 is = 1*100/ 1.25 = 80 % w/w I've post my answer, so why don't you show that answer here with the question. It's fare. I must be informed about my answer weather it is right or wrong. Please inform me at amitmahalwar@yahoo.com
What is the balanced equation for limestone?
...Calcium Carbonate ===> Calcium Oxide(s) + Carbon Dioxide(g). CaCO3(s) + heat ===>CaO(s) + CO2(g). ...Calcium Oxide(s) + Water(l) ===> Calcium Hydroxide(s) CaO(s) + H2O(l) ===> Ca(OH)2(s). ...Calcium Hydroxide(aq) + Carbon Dioxide (g) ===> Calcium Carbonate(s) + Water (l) Ca(OH)2(aq) + CO2(g) ===> CaCO3(s) (suspension) + H2O(l) These equations do not need balancing, they are already balanced.

What chemicl reaction is involed in the formation of limestone caves?
Limestone is calcium carbonate, CaCO3. Water with some carbon dioxide dissolved in it is carbonic acid, H2CO3. Here's the formula: H2CO3 + CaCO3 --> CaO + H2O + 2CO2 This reaction yields water, carbon dioxide, and the mineral calcite, which is primarily what rock formations in caves are made of.
Why does soda dissolve chalk?
Soda is acidic as it contains H2CO3 due to the dissolved CO2 within the soda. Chalk on the other hand is a basically CaCO3 which is a base CaCO3 + H2CO3 ---> CaCO3 + H20 + CO2 The reaction will continue until here is no more H2CO3 left i/e when the soda goes flat. If this occurs before or the carbonate (CO3) is reduce to CO2 then there will be a solid left in the soda in the form of CaCO3
Calcium carbonate reacts with sulphuric acid?
YES!!! It produces calcium sulphate, water and carbon dioxide. Here is the balanced reaction equation. CaCO3(s) + H2SO4(aq) = CaSO4(s) + H2O(l) + CO2(g)
What is chemical composition of limestone?
CaCO3--Calcium carbonate--calcium, carbon, oxygen.
What kind of reaction is represented here 4P 5O2 2P2O5?
Oxidation of phosphorus. 4P(s) + 5O2(g) = 2P2O5(s). (Phosphorus pentoxide.)
What kind of reaction is represented here h2so4 plus 2naoh yields na2so4 plus 2hoh?
That is an acid/base neutralization reaction. The sulphuric acid has been neutralized by the sodium hydroxide, forming 2 water molecules and sodium sulphate.
