We write down the equations of chemical reactions.
1) 2C + O2 = 2CO.
The reaction is called a combustion reaction. The result is the formation of carbon monoxide.
2) 2CO + O2 = CO2.
The reaction is called a combustion reaction. The result is carbon monoxide.
3) 2KOH + CO2 = K2CO3 + H2O.
Reaction refers to an exchange reaction. A compound of potassium carbonate and water is formed.
4) K2CO3 + CaCl2 = CaCO3 + 2KCl.
The reaction is called an exchange reaction. When potassium carbonate and calcium chloride react, the result is calcium carbonate and potassium chloride.
5) CaCO3 + CO2 + H2O = Ca (HCO3) 2.
Reaction refers to the reaction of a compound. As a result of the reaction, calcium bicarbonate is formed.
6) Ca (HCO3) 2 = CaCO3 + CO2 + H2O.
Decomposition to produce calcium carbonate, carbon dioxide and water.
