MgCO3 --(heat)--->MgO+CO2
The chemical equation representing the reaction of magnesium (Mg) with oxygen (O2) to form magnesium oxide is: 2Mg + O2 → 2MgO The "c" in your equation does not have a clear designation in this context.
When magnesium carbonate reacts with nitric acid, it forms magnesium nitrate, carbon dioxide, and water. This is a chemical reaction where the carbonate group in magnesium carbonate is replaced by the nitrate ion from nitric acid. The reaction also releases carbon dioxide gas.
They form magnesium oxide, copper oxide etc. and will form carbon dioxide as a byproduct.
When magnesium chloride solution is mixed with sodium carbonate solution, a white precipitate of magnesium carbonate forms. This is a double displacement reaction where the magnesium ions from magnesium chloride exchange with the carbonate ions from sodium carbonate to form the insoluble magnesium carbonate.
When a carbonate, such as calcium carbonate, reacts with an acid, such as hydrochloric acid, it undergoes a chemical reaction and produces carbon dioxide gas, water, and a salt. The reaction can be represented by the general equation: Carbonate + Acid -> Carbon Dioxide + Water + Salt.
When magnesium reacts with sulfur, it forms magnesium sulfide. The balanced chemical equation for this reaction is: 2 Mg + S -> MgS. The reaction is exothermic, releasing energy in the form of light and heat.
MgSO4+ H2O + CO2
The magnesium will react with the acid to produce hydrogen gas and a magnesium salt.
Calcining magnesium carbonate involves heating it strongly to drive off carbon dioxide, leaving behind magnesium oxide. The process decomposes the compound into its constituent parts, resulting in the formation of magnesium oxide as a final product.
When magnesium reacts with dilute sulfuric acid, magnesium sulfate and hydrogen gas are produced. The balanced chemical equation for the reaction is: Mg + H2SO4 -> MgSO4 + H2. The reaction is exothermic, meaning that it releases heat.
The reaction is: 2 Mg + O2 = 2 MgO
When heated to a sufficiently high temperature, solid magnesium hydroxide will decompose into magnesium oxide and water: Mg(OH)2 -> MgO + H2O.
