What is a exotermic reaction?
An exothermic reaction is a chemical reaction that releases energy in the form of light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation:reactants → products + energy
What is an excothermic change?
An exothermic reaction is a chemical reaction that releases energy either in the form of heat or light. All combusion reactions, for example, are exothermic.
Is biomass chemical energy?
As it decays bacteria catalyses a chemical reaction to release methane and heat. When you burn it a chemical reaction occurs between the biomass and oxygen that releases light and heat. Biomass contains potential energy that can be chemically released.
An exothermic reaction always?
Releases energy by light or heat
Is the chemical reaction of photosynthesis?
6CO2+6H2O+light energy-->C6H12O6+6O2 Chemical reaction of Photosynthesis
What chemical reactions reales energy?
An exothermic reaction is a chemical reaction that releases energy in the form of light or heat. It is the opposite of an endothermic reaction
What is a exotermic reaction?

What is the energy pathway for chemiluminescent light?
okay so the energy pathway is: chemical energy----> visible light energy and how that happens is when two (or more) chemicals mix that causes a chemical reaction. The chemical reaction releases chemical energy, so instead of it the chemical energy releasing too much heat, the energy is used for light instead. So basically Chemiluminescence is the process in which chemical energy produced by a chemical reaction is transformed into light energy.
What energy changes occur when water freezes?
When water freezes, it will go through an exothermic reaction, which is a chemical reaction that releases energy in the form of light or heat. It is expressed in a chemical equation as: reactants --> products + energy
What is the difference an exothermic reaction and an endothermic reaction?
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 .
A change of state in which energy is removed from a substance is called an?
A change of state where energy is removed from a substance is called an exothermic reaction. This chemical reaction releases energy in the form of light or heat.
What is an excothermic change?
An exothermic reaction is a chemical reaction that releases energy either in the form of heat or light. All combusion reactions, for example, are exothermic.
What is exogonic reaction?
there is no exogonic reaction: reactions are either endergonic or exergonic. An exergonic reaction is a chemical reaction that releases energy in the form of heat, light, etc. .. An endergonic reaction is the opposite being a reaction requiring the input of energy.
What is an exothermic reaction?
An exothermic reaction is a chemical reaction that is done by the release of heat. It gives out energy to its surroundings. The energy needed for the reaction to occur is less than the total energy released.
Is biomass chemical energy?
As it decays bacteria catalyses a chemical reaction to release methane and heat. When you burn it a chemical reaction occurs between the biomass and oxygen that releases light and heat. Biomass contains potential energy that can be chemically released.
An exothermic reaction always?
Releases energy by light or heat
A chemical reaction that occurs in plants that changes light energy into chemical energy is?
photosynthesis
