CaCO3 + SiO2 ==Heat==> CaSiO3 + CO2

The products are calcium silicate and carbon dioxide.

When calcium carbonate is heated it undergoes thermal decomposition, to form calcium oxide(CaO) and carbon dioxide.

CaO is a base , because it is a metallic (Group 2) oxide. It reacts with SiO2 , which is an acidic oxide ( because it is a non-metallic (Group 4) oxide.

Remember a base plus an acid form a 'salt'. in this case CaSiO3 .

NB This is the side reaction going on in a blast furnace during iron oxide reduction. The reason for adding the 'flux' calcium carbonate (CaCO3) to remove the silicon dioxide impurity in the iron oxide.

NNB The carbon dioxide (CO2) is NOT released into the atmosphere, but undergoes reduction in excess coke (carbon) to form carbon monoxide (CO), which is the reducing agent of iron ore in the blast furnace.

What kind of chemical reaction is this CaCO3 - CaO CO2?

CaCO3 == heat ==> CaO + CO2 The reaction is ' Thermal Decomposition'.


Oxygen can be obtained by heating?

Oxygen can be obtained from the air by heating it to high temperatures, which causes the oxygen molecules to separate from the nitrogen and other gases in the air. This process is known as fractional distillation or air separation.


How can you convert CaCO3 to Ca?

You can convert CaCO3 (calcium carbonate) to Ca (calcium) by heating it at a high temperature in the presence of a reducing agent, such as carbon. This process, known as calcination, will decompose the calcium carbonate, releasing carbon dioxide and leaving behind calcium oxide. The calcium oxide can then be reacted with water to form calcium hydroxide, which can further be processed to obtain pure calcium.


What is the process of caco3 decomposition and what are the factors that influence it?

The process of CaCO3 decomposition involves breaking down calcium carbonate into calcium oxide and carbon dioxide through heating. Factors that influence this process include temperature, pressure, and the presence of catalysts.


How many electrons are shared in each bond of SiO2?

Silicon dioxide is a network giant molecule, the bonds are ALL single covalent bonds with two electrons. Each silicon is surrounded by four oxygen atoms at the corners of a tetrahedron, each oxygen atom is linked to two silicon atoms.Thereare no double bonds. Molecular SiO2 does not exist- heating SiO2 forms SiO not O=Si=O.

What mass of calcium oxide will be obtained by heating 3 mol of caCO3?

3 mol CaCO3 will produce 3 mol CaO (and 3 mol CO2) on dry-heating. So 3 times the molar mass of CaO (56,1 g/mol) which is 168 g CaO
