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

Answer 1

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'.

Answer 2

The delta H of the reaction, which is ENTHALPY. This is equivalent to the internal change in the energy of a close system under constant pressure.

A negative value indicates an EXOTHERMIC reaction, which means that energy was released during the reaction.

A positive value indicates an ENDOTHERMIC reaction, which means that energy was absorbed into the system in order for the reaction to be completed.

Answer 3

The links the are formed between atoms, their relative positions, etc, are responsible for these energy exchanges.

For example, if an atom A and an atom B are linked together, their energy is lower than is they were apart : indeed, to split them, you need to provide some energy by "pulling them apart".

For a given set of molecules, atoms or whatever, it has an energy that depends of the configuration in which they are : it's the opposite of the energy you need to provide in order to split them all apart.

In a reaction, this energy may vary, resulting in dissipation or absorption of energy from the outside.

Answer 4

When the temperature changes. When it increases, it probably means it is an endothermic change and when the temperature decreases, it probably means that it is an exothermic change.

Answer 5

Measure the temperature. If it rises, energy is being released. If it falls, energy is being absorbed.

Answer 6

The creation of heat is often a sign of an energy release; this indicates an exothermic reaction.

Answer 7

Both, though not simultaneously in equal amounts.

Answer 8

Heat energy and Light energy
