a chemical reaction in which the Gibbs free energy (G) of the products is greater than the Gibbs free energy of the reactants exergonic /ˌek.səˈɡɒn.ɪk/ An exothermic reaction is an exergonic reaction in which energy is released in the form of heat. Anabolic pathways ab...
Nuclear energy is released by three exothermic processes: Radioactive decay, where a proton or neutron in the radioactive nucleus decays spontaneously by emitting a particle Fusion, two atomic nuclei fuse together to form a heavier nucleus Fission, the breaking of heavy nucleus into two nuclei The...
During a chemical reaction, heat is often its by-product. This kind of reaction is known as the exothermic reaction. Some examples that produce chemical energy are coal, batteries, petroleum, food, and natural gas. THERMAL ENERGY Thermal Energy is also known as heat energy. There is a temper...
For solids, the effect of temperature depends on the type of reaction, whether it is endothermic or exothermic. An endothermic reaction is when heat is absorbed, while an exothermic reaction is when heat is released. Endothermic reactions increase the solubility of solid solutes, while endothermi...
The combination produces sodium hydroxide, hydrogen gas and heat (the technical term for these heat-creating reactions is an exothermic). The heat is so intense that it ignites the hydrogen gas, creating an impressive explosion. Scientists have even caught this reaction on high-speed video, ...
The combustion of fossil fuels is a highly exothermic (heat releasing) reaction and produces a huge amount of energy. 4. Who Discovered Fossil Fuels It is unknown who discovered fossil fuels. However, it is claimed that about 4,000 years ago, a person in northern China discovered for the ...
(a base) and hydrogen gas. During the exothermic reaction, the metal may become so hot that it may catch fire and burn with an orange-colored flame. It reacts vigorously with all the halogens (chlorine, fluorine, etc.) forming sodium halides. It dissolves readily in dilute sulphuric acid...

Sulfuric Acid is highly exothermic, the dilution should be done by adding acid to water and not water to acid. Source: encyclopedia 9. Venus Sulfuric Acid The Venus Sulfuric Acid is produced in the upper atmosphere of Venus. It is because of the Sun’s photo-chemical reaction with carbon ...
and chemical-resistant clothing should be worn. The acid should be used under a fume hood or else in a well-ventilated area. Direct contact can cause chemical burns and damage surfaces. Exposure can damage the eyes, skin, and respiratory organs irreversibly. Reaction with oxidizers, such as ch...
