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.
When an electron gets excited is energy released or absorbed?
When an electron gets excited, energy is absorbed to move the electron to a higher energy level. This absorbed energy gets released when the electron returns to its original energy level, emitting electromagnetic radiation such as light.
How are photons absorbed by materials and what happens to them afterwards?
Photons are absorbed by materials when their energy matches the energy levels of electrons in the material. When a photon is absorbed, it can cause an electron to move to a higher energy level or be released as heat. The absorbed energy can also be re-emitted as a new photon or used to create a chemical reaction.
What is a net absorption of energy?
Net absorption of energy refers to the overall amount of energy absorbed by a system or material. It takes into account both the energy absorbed from external sources and the energy released by the system itself. This value is often used to understand the energy balance of a system or process.
If you make the electron jump downward then return it to the outer ring what do you notice about the photon released or absorbed?
When an electron jumps downward to a lower energy state in an atom, it releases energy in the form of a photon which is emitted. When the electron returns to the outer ring, it absorbs energy in the form of a photon. The energy of the photon absorbed is equal to the energy of the photon released during the downward jump.
What is it called when absorbed light energy is released by matter?

When absorbed light energy is released by matter it is called what?

Is energy during evaporation released or absorbed?
energy is released
Is energy absorbed or released during freezing?
Energy is released during freezing.
What determines whether energy will be released or absorbed during a chemical reaction?
The difference in energy between the products and reactants of a chemical reaction determines if energy will be released or absorbed. If the products have lower energy than the reactants, energy will be released in the form of heat or light. If the products have higher energy, then energy will be absorbed.
Is it true that in an exothermic change energy is absorbed?
No. Energy is released
What is the chemical reaction role of energy?
energy is released or absorbed.
In an endothermic change is energy released?
No, energy is absorbed instead.
When 2 atoms combine to form a molecule energy is always absorbed always released never absorbed or released sometimes absorbed and sometimes released?
When 2 atoms combine to form a molecule, energy can be either absorbed or released, depending on the specific atoms involved and the type of bond being formed. This process can result in either an exothermic reaction (energy is released) or an endothermic reaction (energy is absorbed).
When molten solid becomes a solid is energy absorbed or released by the steel?
Energy is released.
When molten steel becomes solid is energy absorbed or released by the steel?
Energy is released.
Is there net absorption of energy when more energy is absorbed than released?
Yes, there is a net absorption of energy when more energy is absorbed than released. This means that the system gains energy overall.
