Because the second (2) reaction is easier and quicker than the first (1) one will not find much MgCO3 in the reaction mixture, and further the escape of CO2 gas makes the last step irreversable.
Mg(HCO3)2 --(1)-> 2MgCO3 + H2O --(2)-> 2MgO + CO2 + H2O
(This is the same as saying magnesium carbonate is less stable than Mg-bicarbonate. At the higher temperature of Mg(HCO3)2 decomposition, MgCO3 is decomposed even faster)
What else can I help you with?
What are the products from the decomposition of sodium bicarbonate?
When sodium bicarbonate decomposes, it forms water, carbon dioxide, and sodium carbonate. Heating sodium bicarbonate causes it to break down into these products.
What is the balanced equation for Heating magnesium carbonate?
Heating magnesium carbonate (MgCO3) results in the decomposition of magnesium carbonate into magnesium oxide (MgO) and carbon dioxide gas (CO2). The balanced equation for this reaction is: 2MgCO3(s) -> 2MgO(s) + 2CO2(g)
Magnesium carbonate when heated?
When magnesium carbonate is heated, it decomposes into magnesium oxide and carbon dioxide gas. This reaction is a thermal decomposition reaction that occurs at high temperatures. The magnesium oxide produced is a white solid, while the carbon dioxide gas is released into the air.
What is the difference between sodium carbonate and sodium hydrogen carbonate when they are heated?
When sodium carbonate is heated, it decomposes to form sodium oxide and carbon dioxide gas. On the other hand, heating sodium hydrogen carbonate causes it to decompose into sodium carbonate, water, and carbon dioxide gas.
What is the skeleton equation representing the heating of magnesium carbonate to produce solid magnesium oxide and carbon dioxide gas?
Fe + S -------> Fe + S . 8 8 8 8

A Carbonate not decomposed by heat?
A carbonate not decomposed by heat is sodium bicarbonate. The bonds of sodium bicarbonate is so strong that too much energy is required to break them down.
What happens when magnesium carbonate is calcined?
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.
What is the difference between sodium carbonate and sodium hydrogen carbonate when they are heated?
When sodium carbonate is heated, it decomposes to form sodium oxide and carbon dioxide gas. On the other hand, heating sodium hydrogen carbonate causes it to decompose into sodium carbonate, water, and carbon dioxide gas.

What happens when magnesium bicarbonate is heated?
When magnesium bicarbonate is heated, it decomposes to form magnesium oxide, carbon dioxide, and water. The decomposition reaction releases carbon dioxide gas, which can be observed as bubbles during the heating process.
What volume of CO2 gas will be evolved at ntp by heating 7.3 g of magnesium hydrogen carbonate?
The volume is 1,1 mL.
What compounds does MgCO3 break into?
With sufficient heating, MgCO3 -> MgO + CO2, magnesium oxide and carbon dioxide.
Is heating potassium bicarbonate a chemical or physical change?
Heating potassium bicarbonate is a chemical change because it causes a decomposition reaction. This results in the formation of new substances (potassium carbonate, water, and carbon dioxide) that have different chemical properties than the original compound.
How do you prepare washing soda?
You can form sodium carbonate (washing soda) by heating sodium bicarbonate (baking soda), which will release carbon dioxide and water. Sodium carbonate is called washing soda because it is a water softener.
