I understand that it is an exothermic reaction, but why?

This reaction is very exothermic (gives out a lot of energy).

At one time it was thought that all chemical reactions were exothermic.

On the other hand, we know that combustion reactions are exothermic.

If a reaction releases heat, that means it is exothermic.

If the reaction is exothermic the opposite effect will be observed.

The reaction is exothermic but has a high activation energy.

This is an exothermic reaction, so steps must be taken to control the temperature.

The reaction is highly exothermic, and can lead to an explosion.

The energy change associated with this exothermic reaction can be calculated using a computer.

The reactions are exothermic, so the temperature increases to 1,700 C.

The change is exothermic (the process releases energy) for the opposite direction.

The reaction is exothermic, therefore the reactor must be cooled.

After this induction period, the reactions can be highly exothermic.

Or does the exothermic energy have mass and that's were we lost the mass.

The dissolution is an exothermic reaction, I hope this helps!

The energy liberated by an exothermic reaction is not converted to mass.

This reaction is highly exothermic, which leads to contaminated products.

Not so much the erection-the plaster is an exothermic reaction.

Its dissolution in water is strongly exothermic, meaning the process gives off significant heat.

It is caused by a highly exothermic reaction taking place in a thin zone.

The splitting of water is not an exothermic reaction.

In a second situation, let us say that A to B is an exothermic reaction.

Combustion is a typical exothermic reaction - any type of burning.

Both of these reactions are exothermic and proceeds with volume contraction.
