Energy is neither created nor destroyed in a chemical reaction Explain where the energy released or absorbed by the reactions comes from or goes to?
Energy released by a chemical reaction is released as heat to the surroundings thus rising the temperature of the room or lab etc where the reaction is taking place. Similarly, energy absorbed by endothermic is either supplied by external heating of reaction mixture over a flame or absorbed from surroundings.

Do reactions create energy?
Reactions do not create energy; rather, they involve the conversion of energy from one form to another. In some reactions, energy is released (exothermic reactions), while in others, energy is absorbed (endothermic reactions). Energy is always conserved in a chemical reaction according to the law of conservation of energy.
The law of what and mass applies to chemical reactions?
The law of conservation of matter/mass applies to chemical reactions. This is why chemical equations must be balanced. The matter that goes into a chemical reaction is present in the products of the reaction, but the atoms have been rearranged to form products with new and unique properties different from the reactants.
How many photons are absorbed during light reaction?
During the light reactions of photosynthesis, hundreds to thousands of photons may be absorbed by a single chlorophyll molecule in the reaction center of a photosystem. These photons provide the energy needed to drive the electron transport chain and convert light energy into chemical energy in the form of ATP and NADPH.
What is the process in which one initial reaction triggers a growing number of subsequent reactions?
That process is called a chain reaction. In a chain reaction, the products of one reaction act as reactants in the subsequent reactions, leading to a self-sustaining series of reactions. This can result in a rapid release of energy, as seen in nuclear reactions or certain chemical reactions.
What is the relationship between kinetics and equilibrium in chemical reactions?
In chemical reactions, kinetics refers to the speed at which a reaction occurs, while equilibrium is the point where the rates of the forward and reverse reactions are equal. Kinetics determines how quickly a reaction reaches equilibrium, and equilibrium represents a balance between the forward and reverse reactions.
Can compounds be created by chemical reactions?
Yes, compounds can be created by chemical reaction. They can also be destroyed by chemical reaction.
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 never destroyed or created in chemical reactions?
An enzyme in a biochemical reaction fits this definition.
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.
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.
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.
How is energy involved in a chemical reaction?
Activation energy is needed to start a chemical reaction. This energy is used to join the reactants together or break them apart. If a reaction is exothermic then it gives energy out. If it is endo thermic then the reaction takes energy in.
Which of the following statements about enzymes is not true A are catalysts B almost all enzymes are proteins C operate most efficiently at optimum pH D destroyed during chemical reactions?
Enzymes are not destroyed during chemical reactions.
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.
What are energy changers?
Chemical reactions usually involve change of heat due to energy absorbed or evolved during reaction.
What is the law that states that mass is neither created nor destroyed during chemical reactions or physical changes?
The law of conservation of matter states that matter cannot be created or destroyed in an ordinary chemical reaction.
Is this an example of chemical reactions Energy is created as atoms are destroyed in chemical reactions?
No Energy can not be created or destroyed, it can only change form Matter cannot be created or destroyed, it can only change form. -- - -- Like stated above, energy can't be destroyed nor created. Only harnessed to only than be used and changed in form. Matter however CAN be destroyed, its exactly what an atomic bomb, hydrogen bomb or nuclear reaction plant does; annihilates molecules harnessing its potential energy. The law of conservation basically states that you either have matter or you have energy.
