There is no symbol that will show weather or not heat is needed in a decomposition reaction.
In a decomposition reaction, a triangle or delta symbol (Δ) is often used to indicate that heat is required for the reaction to occur. This symbol is typically placed above or below the reaction arrow. It signifies that the reactants need to be heated in order to break down into simpler products.
Decomposition reaction: CaCO3(s) --(heat)--> CaOs + CO2(g)
Thermal decomposition is a chemical reaction where a single substance breaks into two or more simple substances when heated. The reaction is usually endothermic because heat is required to break the bonds present in the substance.
The symbol used to represent the heat of reaction in a chemical equation is ΔH. It indicates the enthalpy change of the reaction, which is the heat exchanged during a chemical reaction at constant pressure.
Heat can be used to break compounds because there is a chemical reaction that takes place and it causes the particles in the compound to break
The symbol for heat being applied in a chemical reaction can be effectively utilized to show that heat is needed for the reaction to occur. This can help scientists understand the energy requirements of the reaction and how temperature affects the rate of the reaction.

Thermal decomposition
The symbol used to represent the heat of reaction in a chemical equation is ΔH. It indicates the enthalpy change of the reaction, which is the heat exchanged during a chemical reaction at constant pressure.
This type of reaction is known as a decomposition reaction, where a compound is broken down into simpler substances by either heat, light, electricity, or a chemical reaction. It is the opposite of a synthesis reaction.
The type of reaction that occurs when a compound is broken up by heat is called thermal decomposition. This process involves the breaking down of a compound into simpler substances through the application of heat energy.
When a compound breaks apart into separate substances, it undergoes a chemical reaction known as decomposition. This process is typically driven by heat, electricity, or light and results in the formation of simpler products from the original compound.
Heat can be used to break compounds because there is a chemical reaction that takes place and it causes the particles in the compound to break
The decomposition of mercury II thiocyanate is a chemical reaction that involves the breaking down of the compound into mercury sulfide, carbon disulfide, and nitrogen gas when heat is applied. This reaction is a decomposition reaction, where the compound breaks down into simpler substances.
The type of reaction that involves oxygen and produces light and heat is a combustion reaction.
