The reaction ofanhydrousmagnesium sulfate with water is exothermic. This is a fine white powder. The container must be covered for it will react with water in the air if exposed. The container will feel warm otherwise. In the tests I've done, it gets no higher than 30˚C which is roughly 86˚F. So it is warm, but not hot.
The hydrous magnesium sulfate (epsom salt) is endothermic. This is a crystalized form magnesium sulfate where water is used in thecrystalbonds. To access the magnesium sulfate in its ionized form, the crystal must be broken. This requires energy and thus results in a lower heat yield in he aqueous solution.
Magnesium reacts exothermically with water (cold or hot). Exothermic reactions, or those which produce heat instead of consume it, rely on unstable elements attempting to gain or lose electrons in order to become stable. Magnesium, being an alkaline earth metal, has 2 valence electrons... thus it will react strongly in an attempt to give away those two electrons and become stable. Oxygen (present in water) only has 6 electrons, and will react exothermically in order to gain two electrons. Thus, Mg + H2O > MgO + H2. This reaction will generate heat (exothermic) and the result will be the stable Magnesium Oxide.
Exothermic
The reaction between calcium and water is very exothermic.
Exothermic reaction is just one of the two possible chemical reactions: either exothermic or endothermic. (No difference but heat release)
it is exothermic because heat is liberated to the surrounding during the chemical reation
There will be an strong exothermic reaction which will flame and sputter.
In a reaction between MgCOËÄ and NHËÅBr the new magnesium compound formed would be MgBr2
The difference between endothermic and exothermic energy is that exothermic energy is the reaction that releases energy and endothermic is the reaction in ehich energy is absorbed.
This is a strong exothermic reaction.
Exothermic
EXTREMELY!!!!! exothermic. As in fires and explosions exothermic.
Magnesium oxide is a very inert substance. It does not disolve readily in water but dos dissolve in acids. the reaction with concentrated hydrochloric acid is exothermic.
Endothermic
endothermic because it absorbs energy, and not releasing it
You can generally tell by changes in temperature, whether you have an exothermic reaction which produces heat, or an endothermic reaction which consumes heat.
An endothermic reaction absorbs heat. It cannot proceed without the addition of heat. An exothermic reaction releases heat. Since heat causes chemical reactions to go faster, an exothermic reaction can "feed on itself" and get out of control, releasing damaging amounts of heat and, if proceeding in a closed container, causing an explosion.
The reaction between calcium and water is very exothermic.
exothermic I believe
