Is obtaining lime from limestone exothermic?
The hydratation of concentrated OH- and Na+ ions (by dilution) is exothermic, it gives an energetically prefered state of matter.(Hydratation is the extra surrounding of the ions by polar water molecules of the solvent).
Is it a physical or chemical change when an antacid tablet reacts with hydrochloric acid?
It is a chemical change. Depending on the antacid, the active ingredient in the tablet (which is a base) will react with the hydrochloric acid to produce water, a salt, and sometimes carbon dioxide.
Is an ionic compound exothermic?
A compound is never exothermic. Its reaction with some other substance is endothermic or exothermic like when calcium oxide reacts with water large amount of heat is evolved.
Are all spontaneous processes exothermic?
No. For example ammonium nitrate spontaneously dissolves in water. This is an endothermic process.
What kind of reaction is it when antacid tablet reacts with hydrochloric acid?
The reaction between antacid tablets and hydrochloric acid is classed as an acid-base reaction, and is also called a neutralisation reaction. The base or alkali in the reaction is in the antacid tablet. These reactions produce a salt (not necessarily table salt NaCl) and water.
When silver nitrate reacts with hydrochloric acid the container gets warmer is this reaction exothermic or endothermic?
I think it's exothermic.
When a antacid tablet reacts with hydrochloric acid what is it called?
It is simply acid base neutralization.

What happens when Hydrochloric acid reacts with ammonium hydroxide is this a exotheermic or endothermic?
HCl + NH3 --> NH4Cl is already exothermic Ammonium hydroxide is the solution of NH3 in water, giving the following exothermic reaction: [NH4OH]aq + H+aq + Cl-aq --> NH4+aq + H2Oliq + Cl-aq
Are all spontaneous processes exothermic?
No. For example ammonium nitrate spontaneously dissolves in water. This is an endothermic process.

Is an explosion of hydrogen gas when it reacts with oxygen gas endothermic or exothermic?
Exothermic , since when they react, they form a bond. All bonds that are formed release potential energy , and any exothermic reaction involves a loss of energy.
What happens to hydrochloric acid when it reacts to baking soda?
NaHCO3 + HCL = NaCL + H2O + CO2 The reaction is exothermic ie. it gives out heat during the process.
Is ice cream a exothermic or endothermic reaction?
endothermic reaction. ice - cream melts because it absorbs heat from the surrounding thus increasing its temperature. exothermic reaction is when a substance reacts with something, thus releasing heat.
How does it show if iron reacts with hydrochloric acid?
hydrochloric acid reacts with iron when it starts bubbling , magnesium reacts more though .
