The gas that reacts with calcium and magnesium when they burn is oxygen. This reaction forms calcium oxide and magnesium oxide as the products.
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 formation of calcium oxide is: Ca + O2 -> CaO.
The symbol equation for calcium reacting with water is: Ca + 2H2O -> Ca(OH)2 + H2.
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.
Calcium reacts with fluorine to form calcium fluoride (the symbol is CaF2).
The gas that reacts with calcium and magnesium when they burn is oxygen. This reaction forms calcium oxide and magnesium oxide as the products.

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.
CaCO3 + H2SO4 -> CaSO4 + CO2 + H2O Of course if you don't understand the above, well - you should have asked a better question :-)
THE PLUS SIGN (+)an example is: sodium + oxygen --> sodium oxideNa2 + O --> Na2O
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.
The arrow symbol "→" is used in a chemical equation to indicate the direction in which the reactants are transforming into products.
It is CaCO3, also known as Calcium Carbonate.
The symbol equation for the thermal decomposition of calcium carbonate is: CaCO3(s) -> CaO(s) + CO2(g)
