Powdered: increases surface area the reaction happens over, thereby increasing the rate of reaction
Heat: Provides energy for the reaction. Particles move faster, therefore collide more frequently. also, more particles have sufficient energy to react when they collide. This also increases rate.

Is the heating of calcium carbonate a synthesis reaction?
Heating of calcium carbonate (CaCO3) to produce calcium oxide (CaO) and carbon dioxide (CO2) is a decomposition reaction, not a synthesis reaction. This reaction involves breaking down a compound into simpler substances, rather than combining two or more substances to form a new compound.
How calcium carbonate change into oxides?
The reaction is:CaCO3==heating=====>CaO + CO2
Does heating calcium carbonate produce an endothermic or exothermic reaction?
Heating calcium carbonate (CaCO3) produces an endothermic reaction because energy is absorbed in the form of heat to break the bonds between the calcium, carbon, and oxygen atoms in the compound. This results in the decomposition of calcium carbonate into calcium oxide (CaO) and carbon dioxide (CO2).
What is the equation for heating calcium carbonate?
Calcium carbonate --> Calcium oxide + Carbon dioxide Its an example of thermal decomposition.
What chemical reaction takes place when drops of cold water are added to a white solid formed by heating calium calcium carbonate?
When drops of cold water are added to a white solid formed by heating calcium carbonate (CaCO3), a chemical reaction occurs where calcium hydroxide (Ca(OH)2) is formed. This reaction is a hydration reaction where water molecules react with calcium oxide to produce calcium hydroxide.
How might you increase the reaction rate between calcium carbonate and acid?
Possible actions:- stirring- heating- increase of the acid concentration- fine grinding of calcium carbonate- increasing the pressure
What kind of chemical reaction is this CaCO3 - CaO CO2?
This is a decomposition reaction where calcium carbonate (CaCO3) breaks down into calcium oxide (CaO) and carbon dioxide (CO2) upon heating.
Does calcium carbonate decompose to make calcium oxide and water?
Calcium oxide, or quicklime, can be decomposed chemically into its components, calcium and oxygen. Calcium is an element and cannot be decomposed chemically.
What is the solid formed when calcium carbonate decomposed?
If you're talking about thermal decomposition then the answer is Calcium Oxide (s)
Does calcium carbonate thermally decompse?
Yes, with sufficient heating, calcium carbonate will decompose into calcium oxide and carbon dioxide.
What is the symbol equation for heating limestone?
This reaction is correctly named as 'Thermal Decomposition'. CaCO3(s) ==heat==> CaO(s) + CO2(g) The reaction is heated to 'red' heat.
How do you remove pure calcium carbonate from eggshell?
1. Removing of calcium carbonate: CaCO3 is dissolved in vinegar. 2. Obtaining of pure calcium carbonate: by heating of birds eggshells at moderate temperature, to destroy the proteic matrix.
