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 heated to form calcium oxide and carbon dioxide as shown by the 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.
It decomposes into calcium oxide and carbon dioxide
Calcium carbonate --> Calcium oxide + Carbon dioxide Its an example of thermal decomposition.
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 heated to form calcium oxide and carbon dioxide as shown by the equation CaCO3(s) → CaO(s) + CO2(g).
calcium hydroxide + carbon dioxide = calcium carbonate + water
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
Calcium carbonate + heat= Calcium oxide + carbon dioxide is the word equation for the endothermic reaction which occurs in lime kiln.
I'm going to answer in a word equation Calcium Carbonate--heat--Calcium Oxide+Carbon Dioxide. It's called thermal decomposition.
A reaction between an acid and a carbonate gives a salt, water and carbon dioxide. So the word equation is: acid + carbonate -----> salt + carbon dioxide + water eg: hydrochloric acid + calcium carbonate ----> calcium chloride + carbon dioxide + water See: http://www.sky-web.net/science/reaction-types.htm
Calcium Carbonate + Heat ------------ Calcium Oxide + Carbon Dioxide
A reaction between an acid and a carbonate gives a salt, water and carbon dioxide. So the word equation is: acid + carbonate -----> salt + carbon dioxide + water eg: hydrochloric acid + calcium carbonate ----> calcium chloride + carbon dioxide + water See: http://www.sky-web.net/science/reaction-types.htm
metal carbonate + acid = metal salt + carbon dioxide + water e.g. calcium carbonate + hydrochloric acid = calcium chloride + water + carbon dioxide CaCO3 + 2HCl = CaCl2 + H2O +CO2
When calcium carbonate is heated, it breaks down by thermal decomposition to carbon dioxide & calcium oxide (quicklime). Here is the word equation: Calcium carbonate --> Calcium oxide + Carbon dioxide Here is the chemical equation: CaCO3 (s) --> CaO (s) + CO2 (g)
