it is not a chemical reaction. It is a nuclear reaction and it is called fusion.
Radiant energy is exothermic energy. Fire is a chemical reaction that produces heat. This heat is released as a result of the exothermic chemical reaction.
Exothermic Reaction
Chemical reactions can produce heat and energy but not all chemical reactions produce them. Exothermic reactions produce heat and energy (possibly in the form of photons/light), while endothermic reaction absorb them.
Chemical reactions that produce heat (or energy) are known as Exothermic Reactions. (Example: combustion of fuels)
synthesis
the name your looking for is an "exothermic" reaction, one in which heat energy is released to the surrounding atmosphere the other is an endothermic, which absorbs the energy around it making it a "cold" reaction
exothermic
can heat add energy to the chemical reaction in a glwo stick
Exothermic chemical reactions release energy in the form of heat and sometimes light. A common example would be the combustion (oxidation) of methane*:Methane: CH4 + 2O2 -----> CO2 + 2H2O + Energy (heat and light)* The combustion of methane (natural gas) is commonly used to heat water, cook, and to heat homes.
Exothermic (hyperthermic) reaction: a chemical reaction that releases energy,*Endothermic (hypothermic) reaction: a chemical reaction that absorbs energy.** Energy = heat, light, etc.The direction of Heat transfer:Exothermic reactions transfer heat energy to the environment.Endothermic reactions transfer heat energy from the environment .
Heat energy can stimulate a chemical reaction.
No, a chemical reaction that absorbs energy is called an endothermic reaction. The transfer of heat from the surrounds into the substance. In reactions, energy is always CONVERTED, not created which means that nothing can be converted i.e. heat to chemical if there is no heat or initial energy.
