CaO + H2O → Ca(OH)2
Calcium Oxide + water →Calcium hydroxide
The symbol equation for heating limestone (calcium carbonate) is: CaCO3(s) → CaO(s) + CO2(g) where limestone decomposes into calcium oxide and carbon dioxide upon heating.
With this symbol:
The symbol equation for the reaction of magnesium with oxygen to form magnesium oxide is: 2Mg + O2 -> 2MgO
A general equation doesn't exist; this depends on type of the chemical reaction involved.
This reaction is:MgO + C = Mg + CO2MgO + C -> 2Mg +CO2
The symbol equation for the reaction between calcium and oxygen is: 2Ca + O2 -> 2CaO. This represents the combination of two atoms of calcium with one molecule of oxygen to form two molecules of calcium oxide.
Calcium carbonate is represented by the chemical formula CaCO3. In a symbol equation, the reaction of calcium carbonate with hydrochloric acid can be written as: CaCO3 + 2HCl → CaCl2 + CO2 + H2O.
The symbol equation for the reaction between iodine and hydrogen is: I2 + H2 -> 2HI.
The balanced symbol equation for the reaction between potassium and chlorine is: 2K + Cl2 → 2KCl.
The word equation for calcium carbonate is "calcium carbonate + heat → calcium oxide + carbon dioxide." The symbol equation is "CaCO3 (s) → CaO (s) + CO2 (g)."
The symbol equation for the reaction between chlorine and sodium bromide is: Cl2 + 2NaBr → 2NaCl + Br2.
The symbol equation for the formation of calcium oxide is: Ca + O2 -> CaO.
S+O2 = SO2
