What is the type of chemical reaction in which heat energy is absorbed?
Endothermic reactions.Endo- means 'inside' which is where the energy ends up.Exothermic reactions give off energy. Exo- means 'outside'. Think that a spider sheds an 'exo'skeleton, or a skin on the outside.
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.
What is energy released or absorbed during chemical change called?
It depends. There are two types of chemical reaction int his sense. Exothermic reactions release energy and endothermic reactions absorb it.
What is the difference between a exothermic chemical reaction and a endothermic chemical reaction?
energy released by the reaction or energy absorbed.
What chemical reaction describes where energy is absorbed?
Endothermic, if the energy is in the form of heat.
What is the chemical reaction role of energy?
energy is released or absorbed.
Can energy be taken in a chemical reaction?
Depending on the particular chemical reaction, energy may be either released or absorbed.
What is a unit of energy that can identify the amount of energy released or absorbed by a chemical reaction?
The unit of energy commonly used to identify the amount of energy released or absorbed by a chemical reaction is the kilojoule (kJ).
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.
What is normally liberated or absorbed in a chemical reaction?
energy
What can be absorbed or released as the result of a chemical reaction?
Energy.
What can be absorbed and released as the result of a chemical reaction?
In a chemical reaction, energy can be both absorbed and released. When energy is absorbed, it is required to break bonds in the reactants, and when it is released, it is due to the formation of new bonds in the products. Additionally, atoms and molecules can also be absorbed and released in various forms during a chemical reaction.
