If there is any type of energy given offduring a chemical reaction, it is most likely to be heat or light. However, heat and light often come together, and there are more reactions known to give heat without light than the other way around. Thus, I would go for heat then. (simply put)
What else can I help you with?
Substances are changed into different substances when bonds break and form during?
Chemical bonds are made and broken by chemical reactions. After chemical bonds have been broken, then energy is released, and if a chemical bond is made, then energy is absorbed.
What is released when chemical bonds are broken?
"This is a difficult question to answer exactly since (1) potential energy is not something that is directly measured - it can only be deduced from the heats produced or absorbed in a transformation, and (2) the heat produced or absorbed (enthalpy) in a chemical transformation vary from substance to substance. In general, we expect that when chemical bonds are formed, energy is released - imagine the individual atoms as having energy and have to be slowed down in order that chemical bonds can form. Alternatively, and more accurately, when two atoms spontaneously form a chemical bond it must mean that the entropy of this system has increased, since two separate atoms have more disorganization (entropy) then one complete molecule, then in order for the process to be spontaneous (entropy increases), there must be some heat released. The problem now is relating heat to potential energy. I would rather you relate this to internal energy rather than potential energy (which is not quite directly applicable to chemical systems). If we think of internal energy, we know, by definition, that internal energy is a function of the heat and work that goes in and out of the system. Since most chemical transformations do not involve work, then internal energy is mostly a function of the heat that enters or leaves the system. Thus, when a chemical bond is formed spontaneously, heat leaves the system, the internal energy of the system goes down. You may then think of internal energy as a kind of potential energy and say that because the system is less energetic (since heat left the system) that it must now have a lower potential energy."
What is the difference between an exothermic and 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 .
The change in which ice absorbs energy and melts is a?
Endothermic reactions are those in which energy is absorbed during the reaction. Exothermic reactions are those in which heat is evolved during the reactions.When ice melts its absorbs energy in the form of heat so why it melts,
What is released during nuclear reactions?
Energy (in the form of heat), also free neutrons.Binding energy
How energy is made available by chemical reaction?
in chemical reactions, energy is absorbed or released when chemical bonds are broken and new ones are formed.
What form of energy is released or absorbed in most chemical reactions?
Heat energy.
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.
Can a chemical reaction take place when energy is neither released nor absorbed?
Energy is either released or absorbed in form of heat or light. Energy participates in all reactions.
When chemical reactions occur energy is always absorbed?
No, chemical reactions can be endothermic or exothermic.
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.
Can energy released during a chemical reaction be absorbed?
Yes, for ex. thermal energy.
What type of energy is a chemical energy form of?
Chemical energy is a form of potential energy that is stored within the bonds of atoms and molecules in a substance. When chemical reactions occur, this energy is released or absorbed.
Is heat a form of energy released during a chemical reaction?
Yes, heat is often released or absorbed during a chemical reaction. This is because chemical reactions involve the breaking and formation of chemical bonds, and the energy difference between these bonds is released or absorbed in the form of heat.
Identify the type of energy that is stored in a molecule's bonds?
Chemical energy is stored in a molecule's bonds. This type of energy is released or absorbed during chemical reactions.
What is the energy stored in chemical composition?
The energy stored in chemical composition is known as chemical energy. It is the potential energy stored in the bonds between atoms within a molecule. This energy can be released or absorbed during chemical reactions.
What are the chemical changes of electriciy?
CHEMICAL Chemical energy is stored in the bonds between atoms. This stored energy is released and absorbed when bonds are broken and new bonds are formed - chemical reactions. Chemical reactions change the way atoms are arranged. These reactions both absorb and release energy, but the net reaction releases energy.
