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.
The reaction between magnesium and oxygen gas to produce magnesium oxide is a combustion reaction. Combustion reactions are exothermic, producing light and heat as they release energy in the form of heat.
An example of a chemical reaction that absorbs heat is the reaction between baking soda (sodium bicarbonate) and vinegar (acetic acid) to produce carbon dioxide gas. This reaction is endothermic, meaning it absorbs heat from its surroundings, causing the mixture to feel cold to the touch.
The reaction between calcium and water is very exothermic.
This reaction is exothermic because it releases heat energy. The reaction between silver nitrate and hydrochloric acid generates a salt and releases heat as a byproduct.
A chemical reaction is a process that involves the breaking and forming of chemical bonds to create new substances. An exothermic reaction is a type of chemical reaction that releases heat energy to the surroundings. In other words, all exothermic reactions are chemical reactions, but not all chemical reactions are exothermic.
The reaction between sulfuric acid and magnesium is exothermic because it releases heat energy as a result of forming new chemical bonds in the products.
I don't know for sure, but it is probably exothermic. (PLEASE CORRECT ME!)
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.
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.
You can generally tell by changes in temperature, whether you have an exothermic reaction which produces heat, or an endothermic reaction which consumes heat.

The reaction between potassium permanganate and glycerin is exothermic, which means it releases heat as it proceeds. This reaction is highly exothermic and can lead to spontaneous combustion in some cases.
It is a exothermic reaction. So there is nothing similar.
Neutralisation reaction will take place. HCl + NaHCO3 ---> NaCl + H2O + CO2
energy released by the reaction or energy absorbed.
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.
