When a nuclear fission reaction occurs an enormous amount of energy is released This energy comes from?

The release of excess binding energy.


A reaction that releases energy as it occurs is classified as?

A reaction that releases energy is exothermic.


Coupling occurs when the energy released by an exergonic reaction is?

captured and used to drive an endergonic reaction. This allows the energy released by one reaction to be harnessed and used to power a different reaction that would not occur spontaneously. Coupling reactions are essential for many biological processes that require energy input.


The energy released when a chemical compound reacts to produce new compounds?

This is known as the heat of reaction, which represents the energy change that occurs during a chemical reaction. It can be exothermic (energy is released) or endothermic (energy is absorbed). Heat of reaction is typically measured in kilojoules per mole of the reactants.


How energy generated by chemical reaction is converted into light energy?

When a chemical reaction occurs, energy is released in the form of light through a process called chemiluminescence. This occurs when the reactants in the chemical reaction convert their energy into excited electronic states, which then release energy in the form of photons (light) as they return to their ground state. This phenomenon is commonly seen in glow sticks and fireflies.


What is the reaction in which energy is released?

A reaction that releases energy is usually termed exothermic reaction. Energy is usually released as heat.


The energy for an endergonic reaction comes from what kind of reaction?

The energy for an endergonic reaction can come from an exergonic reaction, where energy is released. This released energy is then used to drive the endergonic reaction forward.


Why is carbon used for breathing?

When the chemical reaction involved in respiration occurs, carbon dioxide is released along with water, and energy.


In what form is the energy released in this reaction?

In an exothermic reaction heat energy is released.


What type of chemical reaction occurs energy is given out causing temperature to go up?

An exothermic reaction occurs when energy is released, causing the temperature to increase. In this type of reaction, the products have lower energy levels than the reactants, resulting in the release of heat.


Where is the energy which is released during a chemical reaction stored to begin with?

The energy released during a chemical reaction is stored in the chemical bonds of the reactant molecules before the reaction occurs. During the reaction, these bonds are broken, and new bonds are formed, releasing the stored energy in the process.


Which of these occurs during an endothermic reaction?

energy is absorbed
