Being exothermic relates to a reaction of two substances which give out heat to the surroundings. As such, hydrochloric acid can't be exothermic by itself.
If you add concentrated hydrochloric acid to water, however, heat is generated in the reaction which is one of the reasons why hydrochloric acid should only be diluted in this way (acid added to water, not the other way round) otherwise the solution can quickly and violently boil over and cause acid and heat burns to anything it touches.

The dissociation of hydrochloric acid in water is an exothermic process, meaning it releases heat energy. This can be observed by the increase in temperature when hydrochloric acid is added to water.

Is the reaction of sodium bicarbonate with hydrochloric acid endothermic or exothermic?
The reaction of sodium bicarbonate with hydrochloric acid is exothermic. This is because heat is released during the reaction as the chemical bonds are broken and new bonds are formed.
Is hydrochloric acid dissolving in water an exothermic reaction?
Yes, the dissolution of hydrochloric acid in water is an exothermic reaction because it releases heat energy. This is due to the formation of hydrogen ions and chloride ions from the dissociation of the acid molecules.
When hydrochloric acid neutralizes sodium hydroxide the temperature increases is this exothermic or endothermic?
The increase in temperature when hydrochloric acid neutralizes sodium hydroxide is due to an exothermic reaction. Exothermic reactions release heat energy as they proceed.
What is formed if you mix hydrochloric acid with amonia?
When hydrochloric acid reacts with ammonia, it forms ammonium chloride. This reaction is highly exothermic and produces white fumes of ammonium chloride.
Is adding dilute hydrochloric acid to magnesium oxide an exothermic reaction?
Yes, the reaction between dilute hydrochloric acid and magnesium oxide is exothermic because it releases energy in the form of heat. It is a chemical reaction that results in the formation of magnesium chloride and water.
Why is magnesium plus hydrochloric acid an exothermic reaction?
When magnesium reacts with hydrochloric acid, it forms magnesium chloride and hydrogen gas. This reaction releases energy in the form of heat, making it exothermic. The breaking and forming of chemical bonds during the reaction releases more energy than is required to break the initial bonds, resulting in a net release of heat.
Is the reaction of sodium bicarbonate with hydrochloric acid endothermic or exothermic?
The reaction of sodium bicarbonate with hydrochloric acid is exothermic. This is because heat is released during the reaction as the chemical bonds are broken and new bonds are formed.
Is hydrochloric acid dissolving in water an exothermic reaction?
Yes, the dissolution of hydrochloric acid in water is an exothermic reaction because it releases heat energy. This is due to the formation of hydrogen ions and chloride ions from the dissociation of the acid molecules.
Why does magnesium ribbon increase the temperature of hydrochloric acid?
When magnesium ribbon is added to hydrochloric acid, a chemical reaction occurs that releases energy in the form of heat. This reaction produces magnesium chloride and hydrogen gas, which results in an increase in temperature of the solution.
A strip of zinc is dropped into a test tube of hydrochloric acid?
an exothermic reaction
Is adding dilute hydrochloric acid to magnesium oxide an exothermic reaction?
Yes, the reaction between dilute hydrochloric acid and magnesium oxide is exothermic because it releases energy in the form of heat. It is a chemical reaction that results in the formation of magnesium chloride and water.
When silver nitrate reacts with hydrochloric acid the container gets warmer is this reaction exothermic or endothermic?
I think it's exothermic.
What is the product for sodium hytdroxide and hydrochloric acid?
Sodium hydroxide + Hydrochloric acid ----> Sodium chloride + Water It is a neutralization reaction and is also exothermic. Products are Sodium chloride and water.
What is the reaction between hydrochloric acid and potassium metal?
There will be an strong exothermic reaction which will flame and sputter.
When hydrochloric acid neutralizes sodium hydroxide the temperature increases is this exothermic or endothermic?
The increase in temperature when hydrochloric acid neutralizes sodium hydroxide is due to an exothermic reaction. Exothermic reactions release heat energy as they proceed.
What type of energy change associated with chemical reaction between magnesium and hydrochloric acid?
This reaction is exothermic.
What can you combine hydrochloric acid with to form exothermic reaction?
Caustic soda solution - even worse - metallic sodium which would be so exothermic it would ignite
