The chalky white substance is calcium carbonate.
CaCO3 -----> CaO + CO2
CaCO3 ==> CaO + CO2
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
The balanced chemical equation for limestone (calcium carbonate, CaCO3) being heated strongly in air is: CaCO3(s) → CaO(s) + CO2(g)
I'm sure it's an oxidation reaction. calcium + oxygen gas ---> Calcium oxide
No such substance as 'CaCo2'. Do you mean calcium carbonate, in which case the formula is 'CaCO3'? or do you mean an alloy(mixture) of 1 part calcium(Ca) to 2 parts cobalt(Co)?
I don't know the equation but i have heard that down in certain depths calcium bicarbonate can be decomposed. However if it helps the equation to make calcuim bicarbonate is: Carbon dioxide + calcium carbonate + water Leads to Calcium Bicarbonate best i could do, I've been researching for a phytoplankton that decomposes calcium bicarbonate, that's how i found this and thought i should help contribute any of my knowledge, Kimo,
Calcium oxide, or quicklime, can be decomposed chemically into its components, calcium and oxygen. Calcium is an element and cannot be decomposed chemically.
Calcite (calcium carbonate) is decomposed by heating.
The word equation for calcium reacting with oxygen is: calcium + oxygen → calcium oxide.
The word equation for the reaction between calcium and phosphorus is: calcium + phosphorus → calcium phosphide.
The word equation for the reaction between calcium and fluorine is: calcium + fluorine → calcium fluoride.
When calcium carbonate (CaCO₃) is heated strongly, it undergoes a thermal decomposition reaction. This process breaks down calcium carbonate into calcium oxide (CaO) and carbon dioxide (CO₂) gas. The reaction can be represented by the equation: CaCO₃ (s) → CaO (s) + CO₂ (g). This reaction is commonly used in the production of lime for various industrial applications.
