Yes, but rather: 'most of all' combination reactions are exothermic. This is mostly true for spontaneous, common reactions.Examples of the contrary endothermic reactions, though rare, are:The formation reaction (= combination 'pur sang') of ethene, propene, acetylene, and even benzene is endothermic, when combined out of elements (that's why they are called endothermic compounds). Further a lot of metal hydride's, chlorous oxide: ClO2 are endothermic.The most Exceptional Endothermic Compound is:Dicyanoacetylene, IUPAC-name: but-2-ynedinitrile, C4N2 (or more structural: NC-CC-CN)Standard heat of formation Ho298 ( 4C + N2 --> ) is 500.4 kJ/molBecause of its high endothermic heat of formation, it can explode to carbon powder and nitrogen gas (reversed formation reaction, exo. 500.4 kJ/mol).It burns in oxygen with a bright blue-white flame at a temperature of 5260 K, which is probably the hottest flame of any chemical.
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.
When chalk (calcium carbonate) is heated, it undergoes thermal decomposition to form calcium oxide (quicklime) and carbon dioxide gas. This reaction is predominantly endothermic, requiring heat energy to drive the decomposition process.
The decomposition of NOBr is endothermic, meaning it requires an input of energy to break down the compound into its constituent elements (NO and Brâ‚‚).

Endothermic means that a reaction needs heat to occur. Limestone needs to be heated to decompose into calcium oxide and carbon dioxide

Thedecompositionof water is endothermic since energy is required to break up the bonds between the hydrogen and oxygen in the water molecule. Therefore the decomposition of water absorbs energy, making the reaction an endothermic one.
The decomposition of phosphorus pentachloride (PCl5) is endothermic because it requires energy to break the bonds holding the compound together. This process absorbs heat from the surroundings, resulting in a decrease in temperature.
Turning water into hydrogen and oxygen is an endothermic reaction called electrolysis. An endothermic reaction only continues while energy is being added to the reactants.
An endothermic reaction is a chemical reaction in which heat is absorbed from the surroundings, causing the temperature to decrease. This type of reaction requires an input of energy to break the bonds of the reactants before new bonds are formed in the products. Examples include the reaction between ammonium nitrate and water, or the photosynthesis process in plants.

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 endothermic reaction that breaks down mercury (II) oxide into mercury and oxygen is classified as a decomposition reaction. In a decomposition reaction, a single compound breaks down into two or more simpler substances. In this case, mercury (II) oxide decomposes into mercury and oxygen when heat is applied to the system.
Endothermic-take in Heat, as opposed to exothermic which gives off heat-like a fire or explosion.
A chemical reaction that doesn't release energy is an endothermic reaction. There are few reactions that are endothermic compared to exothermic reactions (reactions that release energy as heat). Endothermic reactions actually take in heat from the environment and that is why you see a temperature drop. Examples of endothermic reactions: Electrolysis A reaction between ethanoic acid and sodium carbonate A thermal decomposition reaction (as you put heat into the reaction to break something down) Hope this helped.
