A decomposition reaction needs the addition of a catalyst or heat to proceed. For instance hydrogen peroxide will break down into water and oxygen gas in the presence of a catalyst; and calcium carbonate will break down into calcium oxide and carbon dioxide gas when heated.

What kind of symbol is used to show that heat is needed in decomposition reaction?
There is no symbol that will show weather or not heat is needed in a decomposition reaction.
What is action of heat on salts?
- Melting or - Sublimation or - Vaporization or - Thermal decomposition
When you heat a chemical compound does the heat destroy some of the mass?
The mass may be modified by oxidation or thermal decomposition.
What could be done to increase the rate of decomposition of CaCO3?
Just heat it up.
What type of reaction is this caco3s-heat- caos co2g?
Decomposition reaction: CaCO3(s) --(heat)--> CaOs + CO2(g)
What is the effect of heat on decomposition?
Heat speeds up the decomposition process
Does heat help decomposition?
yes
What kind of symbol is used to show that heat is needed in decomposition reaction?
There is no symbol that will show weather or not heat is needed in a decomposition reaction.
If you break a compound down by using heat it is called?
Solids melt on heating. A2. But if you are thinking of the destruction of the material, perhaps pyrolysis is what you seek.
Thermal decomposition and decomposition temperature-is it refer to the same things?
Thermal decomposition is the process by which chemical bonds are broken in the presence of heat. Decomposition temperature is the temperature at which thermal decomposition occurs, which differs for different compounds.
How does presence of light affect the rate of decomposition?
light will produces heat which will speed up the rate of decomposition.
What does the decomposition of organic matter by heat describe?
Pyrolysis
Why is decomposition of vegetable matter into compost considered to be exothermic?
This is because, all thermal decomposition ( and all decomposition processes ) is an exothermic process. Well, if you need a full explanation, here goes. More energy is given off to form bonds then taken in to break bonds hence it is an exothermic reaction. Also, decomposition gives off heat energy.
What is it called when heat breaks up a substance?
Thermal Decomposition
What kind of reaction is Copper II hydroxide plus heat?
Decomposition!
What is action of heat on salts?
- Melting or - Sublimation or - Vaporization or - Thermal decomposition
What conditions favour decomposition?
Oxygen, Heat, moisture, all the core things a living thing needs, since microbes carry out decomposition.
