What is the word used to describe a chemical reaction in which energy is released?

∙ 16y ago
Any chemical reaction that releases energy is called an exothermic action. The equations for an exothermic reaction between substance A and substance B would be:
A + B --> AB + Heat
The heat represents the energy and we can tell it is being released because it is on the product side of the equation. The reverse reaction would be endothermic, meaning it requires energy, heat would be on the reactant side and the equation would be:
AB + Heat --> A + B
To sum things up, an exothermic reaction releases energy and heat will be on the product side of the equation. An endothermic reaction requires energy and heat will be on the reactant side of the equation.

What does chemical energy mean?
That part of the energy in a substance that can be released by a chemical reaction
True or false when a bond is broken in a chemical reaction heat energy is released?
It is true that when bonds are broken there is chemical reaction. Then heat energy is released.
What can be absorbed and released as the result of a chemical reaction?
Energy in the form of heat.
How is chemical energy stored in coal released?
Burning of coal is an exothermic chemical reaction (with release of heat).
What is it called when energy is released or absorbed during chemical change called?
exothermic reaction When energy is released in a chemical reaction it is called an exergonic reaction. One example of an exergonic reaction is cellular respiration in both plants and animals. It is represented by a negative change in free energy (-∆G). An exothermic reaction is only the release of energy as heat, so the more correct answer would be an exergonic reaction, which is the release of energy.
Which type of energy is released in chemical?
Chemical energy is released during a chemical reaction.
What is the difference between a exothermic chemical reaction and a endothermic chemical reaction?
energy released by the reaction or energy absorbed.
Is chemical energy released during a chemical reaction?
exothemic energy
What does chemical energy mean?
That part of the energy in a substance that can be released by a chemical reaction
Can energy be taken in a chemical reaction?
Depending on the particular chemical reaction, energy may be either released or absorbed.
What is the best term to describe a chemical reaction that absorbs heat energy?
An endothermic reaction.
True or false when a bond is broken in a chemical reaction heat energy is released?
It is true that when bonds are broken there is chemical reaction. Then heat energy is released.
What is the chemical reaction role of energy?
energy is released or absorbed.
Energy is released when?
For example in an exothermic chemical reaction.
When is energy released during a a chemical reaction?
When chemical bonds form
When energy released during a chemical reaction?
When chemical bonds form
What is difference between released chemical energy and absorbed chemical energy?
When chemical energy is released, it is released to the environment in the form of heat. This heat can be felt and measured. When a reaction results in an increase in temperature, energy has been released (it gets hot), and you have an exothermic reaction. When chemical energy is absorbed, it is taken from the environment. This causes a decrease in the temperature of the surroundings. Energy has been absorbed from the environment around the reaction (it gets cold), and you have an endothermic reaction.
