How is energy conserved in an endothermic reaction?

Energy is conserved in an endothermic reaction because the heat absorbed becomes potential energy. This potential energy isn't lost energy, it's simply stored, instead of being used.


What is an endothermic reaction?

An endothermic reaction is one that absorbs heat from the surroundings.


What happens to energy in an endothermic reaction?

An endothermic reaction is a reaction which requires energy. The enegry is required for the reaction to take place, maning the energy is used up in the reaction. An example of an endothermic reaction is photosythesis.


Is bond formation endothermic?

Yes, bond formation can be either endothermic or exothermic, depending on the specific bonds being formed. In an endothermic reaction, energy is absorbed to break existing bonds and form new ones.


How is endothermic reaction identified?

It requires heat as a reactant.


When enthalpy in a system increases what is the reaction considered to be?

When enthalpy in a system increases, the reaction is considered to be endothermic. This means that heat is being absorbed from the surroundings, resulting in an increase in the energy of the system.


What types of energy are released in exothermic reactions?

Exo -> Greek "Outside" Therm -> thérmē -> Greek "Heat" So an exothermic reaction releases heat energy. Related to that type of reaction is the endothermic reaction in which heat is absorbed into the reaction rather than being released by it.


When the temperature changes cause of a reaction is it exothermic or endothermic?

If the temperature increases during a reaction, it is exothermic. This means that heat is being released into the surroundings. If the temperature decreases during a reaction, it is endothermic, meaning heat is being absorbed from the surroundings.


Endothermic means that heat has evaporated?

in an endothermic reaction the reacting substances are releasing energy, making them feel cold. i don't know what you mean by evaporating heat, but you cannot create or destroy energy if that helps.


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).


What energy may be released and absorbed during a chemical reaction?

With the firm knowledge that most chemical reactions take place within the armpit, we know that the aliginds folicules release energy during these processes which cause bodily odour better know in latin as stinkas octimas. If the armpits fail at this scientific process the bumhole will assist in the releasing of the 'stinkas octimas'.


Is a firecracker exploding an example of an endothermic reaction or an exothermic reaction?

Exothermic Reaction because the fizzing is CO2 being released as heat (energy).
