What is the word used to describe a chemical reaction in which energy is released?
Any chemical reaction that releases energy is called an exothermic action. The equations for an exothermic reaction between substance A and substance B would be: A + B --> AB + Heat The heat represents the energy and we can tell it is being released because it is on the product side of the equation. The reverse reaction would be endothermic, meaning it requires energy, heat would be on the reactant side and the equation would be: AB + Heat --> A + B To sum things up, an exothermic reaction releases energy and heat will be on the product side of the equation. An endothermic reaction requires energy and heat will be on the reactant side of the equation.
Are titrations endothermic or exothermic?
In thermometric titration the reaction enthalpy is used to follow the chemical reaction. I guess it dépends on the titration reaction it can be exothermic or endothermic. ΔHr (molar heat of reaction) negative (indicating an exothermic reaction) or positive (indicating an endothermic reaction
Is the reaction of magnesium sulphate and water exothermic or endothermic?
The stuff is actually used in some hotpacks. It's exothermic.
What term is used for the type of chemical reaction that gives out heat energy?
Exothermic reaction gives free heat (energy).
Why is sodium not used for cutlery?
Sodium is highly reactive with water and dissolves in an exothermic reaction.

How do you indicate that a catalyst was used in a reaction?
You write the name over the arrow in the chemical equation.

Is the chemical reaction for aluminum exothermic or endothermic?
Yes it is. When these two chemicals react, the container they are in becomes heated. Exothermic refers to a release of heat and energy.
What happens in sodium metal in water?
It is very reactive and can even be explosive depending on how much sodium is used. The equation for this exothermic reaction is: 2Na(s) + 2H2O(l) --> 2NaOH(aq) + H2 (g) + heat

exothermic
Where are endothermic and exothermic reaction used in industry?
i dony know
Is the reaction of magnesium sulphate and water exothermic or endothermic?
The stuff is actually used in some hotpacks. It's exothermic.
Can a exothermic reaction be used to fire an engine?
Yes. That is exactly what we use today. Most engines are powered by an exothermic reaction between gasoline or a similar fuel with oxygen.
What kind of bond does a exothermic reaction have?
Whether a reaction is exothermic or endothermic is not dependent upon the type of bond. Exothermic reactions can involve ionic or covalent bonds. When an ionic substance dissolves, it is often an exothermic reaction, as are many reactions involving covalent bonds, such as combustion.
Is ammonium endo or exothermic?
endothermic but don't know why? As AN crystals are formed the reaction is exothermic. Endothermic when it melts back with water. This is the reason AN is used in cold packs.
Why photosynthesis is considered endothermic reaction?
Plants absorb sunlight and this heat is used for prepairing their food that's why its a exothermic reaction.
