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.

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.
Does energy decrease or increase during a chemical reaction?
Energy can either decrease or increase during a chemical reaction depending on whether it is an exothermic reaction (energy is released) or an endothermic reaction (energy is absorbed). In an exothermic reaction, energy is released in the form of heat, and in an endothermic reaction, energy is absorbed from the surroundings.
Chemical potential energy in a sentence?
Chemical potential energy is the energy stored in the chemical bonds of a substance that can be released during a chemical reaction.
Chemical changes release energy?
Chemical changes can either absorb or release energy. When a chemical reaction releases energy, it is called an exothermic reaction. This means that the products of the reaction have lower energy than the reactants, and the excess energy is released in the form of heat or light.
What is the role of energy in chemical reactions?
Energy is required to break chemical bonds in reactant molecules in order to initiate a chemical reaction. This initial input of energy is called activation energy. In addition, energy is released or absorbed during a chemical reaction, which can result in changes in temperature.
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?
Chemical energy is a form of potential energy stored in the bonds of chemical compounds. When chemical reactions occur, this energy is released or absorbed. It is the energy that holds atoms together in molecules and is important for various biological processes and industrial applications.
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.
Energy is what in a chemical change?
In a chemical change, energy is either absorbed or released. When bonds are broken, energy is absorbed (endothermic reaction), and when bonds are formed, energy is released (exothermic reaction). Overall, the total energy of the system may change during 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 is the chemical reaction role of energy?
energy is released or absorbed.
Energy is released when?
For example in an exothermic chemical reaction.
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.
When is energy released during a a chemical reaction?
When chemical bonds form
