CaCO3 ____> CaO+CO2
Calcium carbonate heated to form calcium oxide and carbon dioxide as shown by the equation CaCO3(s) → CaO(s) + CO2(g).
Calcium carbonate is heated to from calcium oxide and carbon dioxide as illustrated by the chemical equation CaCO3(s) ===> CaO(s) + CO2(g).
Carbon dioxide does not react with calcium carbonate unless water is present. Carbon dioxide plus calcium carbonate plus water produces calcium bicarbonate. The balanced chemical equation is:CO2(g) + CaCO3(s) + H2O(l) --> Ca(HCO3)2(aq)
To determine the volume of carbon dioxide needed, you would need to know the stoichiometry of the reaction between carbon dioxide and calcium carbonate. In this case, since 20 grams of calcium carbonate is given, you would convert that to moles using the molar mass of calcium carbonate. Then, using the balanced equation, you can determine the mole ratio between carbon dioxide and calcium carbonate. Finally, using the molar volume of carbon dioxide gas at the given conditions (usually 22.4 L/mol at standard temperature and pressure), you can calculate the volume of carbon dioxide needed.
When carbon dioxide is treated with limewater (calcium hydroxide solution), a white precipitate of calcium carbonate forms. This is a chemical reaction that is commonly used to test for the presence of carbon dioxide gas.
Calcium carbonate --> Calcium oxide + Carbon dioxide Its an example of thermal decomposition.
Calcium carbonate heated to form calcium oxide and carbon dioxide as shown by the equation CaCO3(s) → CaO(s) + CO2(g).
Calcium carbonate is heated to from calcium oxide and carbon dioxide as illustrated by the chemical equation CaCO3(s) ===> CaO(s) + CO2(g).
Calcium carbonate reacts with methanoic acid to produce calcium methanoate, carbon dioxide, and water. The word equation for this reaction is: calcium carbonate + methanoic acid → calcium methanoate + carbon dioxide + water.
Calcium carbonate + heat= Calcium oxide + carbon dioxide is the word equation for the endothermic reaction which occurs in lime kiln.
The word equation for the reaction between nitric acid and calcium carbonate is: nitric acid + calcium carbonate → calcium nitrate + carbon dioxide + water.
calcium hydroxide + carbon dioxide = calcium carbonate + water
Calcium Carbonate + Heat ------------ Calcium Oxide + Carbon Dioxide
Calcium carbonate thermally decomposes when heated to form calcium oxide powder and carbon dioxide gas. The word equation: calcium carbonate --> calcium oxide + carbon dioxide As a symbol equation: CaCO3 --> CaO + CO2
metal carbonate + acid = metal salt + carbon dioxide + water e.g. calcium carbonate + hydrochloric acid = calcium chloride + water + carbon dioxide CaCO3 + 2HCl = CaCl2 + H2O +CO2
Chemical reaction formula: CaCO3 -> Ca O + CO2
Calcium is an element and does NOT thermally decompose. However, I think you mean Calcium Carbonate. The word equation for it's thermal decomposition is. Calcium Carbonate ==heat==> Calcium Oxide (Lime) and Carbon Dioxide. Here is the BALANCED reaction equation. CaCO3(s) ==heat==> CaO(s) + CO2(g)
