no , is the chemical formula

A formula would be helpful here...
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
In the redox reaction between iodine (I₂) and thiosulfate (S₂O₃²⁻), the half-reaction for iodine is the reduction of I₂ to iodide (I⁻). The half-reaction can be represented as: [ \text{I}_2 + 2 \text{e}^- \rightarrow 2 \text{I}^- ] For thiosulfate, it acts as a reducing agent and is oxidized to sulfate (SO₄²⁻), but the focus here is on the reduction of iodine.
Limestone is primarily composed of the mineral calcite (calcium carbonate, CaCO3) and may also contain clay, silt, and silica in varying amounts. Other minerals such as dolomite (calcium magnesium carbonate, CaMg(CO3)2) may also be present in some limestone formations.
calcium, and carbon trioxideSteve here! you are correct young one but to be even more vague they are Calcium, Carbon and a good helping(3) of oxygen.
The reaction you provided is a double displacement reaction. In this reaction, calcium carbonate (CaCO3) reacts with sulfuric acid (H2SO4) to produce calcium sulfate (CaSO4), water (H2), and carbon dioxide (CO2).
Synthesis
Calcium carbonate and Hydrochloric acid = Calcium chloride, water and carbon dioxide. Here is the BALANCED reaction equation. CaCO3(s) + 2HCl(aq) = CaCl2(aq) + H2O(l) + CO2(g)

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.
The reaction between calcium carbonate and sulfuric acid produces calcium sulfate, carbon dioxide, and water. This is a chemical reaction where the calcium carbonate (CaCO3) reacts with sulfuric acid (H2SO4) to form calcium sulfate (CaSO4), carbon dioxide (CO2), and water (H2O).
Soda is acidic due to carbonic acid and phosphoric acid, which can react with the calcium carbonate in chalk to form calcium citrate or calcium phosphate. This reaction allows the chalk to dissolve in the soda.
The reaction described is a classic example of a single displacement reaction, where a metal displaces hydrogen in an acid to form a salt and release hydrogen gas.
The reaction represented is the combustion of phosphorus (P) in the presence of oxygen (O₂) to form diphosphorus pentoxide (P₂O₅). This is a synthesis reaction where two or more reactants combine to form a single product.
This is a chemical reaction known as a single displacement or redox reaction. In this reaction, aluminum (Al) replaces hydrogen (H) in hydrochloric acid (HCl) to form aluminum chloride (AlCl3) and hydrogen gas (H2).
This reaction is a neutralization reaction between an acid (containing hydrogen ions) and a nonmetal oxide to form water. This type of reaction is also known as the reaction between an acid and a base to neutralize each other and form a salt and water.
This reaction is a single displacement reaction where zinc (Zn) displaces sodium (Na) from sodium chloride (NaCl) to form zinc chloride (ZnCl2) and elemental sodium (Na).
