An endothermic reaction is one in which thermal energy, or heat, is absorbed. If heat is absorbed in the reaction process, it is endothermic. By monitoring the temperature of the reactants in a reaction, an observer could identify an endothermic reaction through observation of a decrease in the temperature.
What else can I help you with?
If the reaction gets hot is it an endothermic or an exothermic reaction?
The reverse reaction is not always endothermic or exothermic, the reverse reaction is the opposite of whatever the initial reaction is, so if the reaction is endothermic, the reverse reaction is exothermic and vise versa.
Sulfuric acid and magnesium ribbon endothermic or exothermic?
I don't know for sure, but it is probably exothermic. (PLEASE CORRECT ME!)
Is the reaction between copper sulphate and hydrochloric acid endothermic?
No, the reaction between copper sulfate and hydrochloric acid is exothermic, meaning it releases heat. This is because energy is released when the products are formed, making the overall reaction exothermic.
Does an exothermic reaction contain more chemical energy than reactants?
depends , if the reaction is endothermic or exothermic. if the reaction is endothermic , the energy needed to break the bonds is greater than the energy that forms bonds.and to break bonds you need thermal energy , meanwhile forming bonds gives off energy. now if the reaction is exothermic the energy given off the bonds form are greater than the enrgy needed to break them. you know if the reaction is exothermic or endothermic because exothermic have a negitave delta next to d eqn.while endothermic have a positive delta.
How do you know that given chemical equation is exothermic or endothermic?
Chemical reactions are about making and breaking bonds. You have to add up how much energy is used to break the chemical bonds of the reactants, and subtract this from the total amount of energy used to make the bonds of the product(s). To do this, you need to know how much energy is needed to make/break each bond. Here are some examples: C-H 98 O-H 110 C-C 80 C-O 78 H-H 103 C-N 65 O=O 116(2 x 58) C=O 187(2 x 93.5) C=C 145 (2 x 72.5) These are all in kcal/mole. When you've worked this out, if the end number is negative then the reaction is exothermic, if the answer's positive, then it's endothermic. Alternatively you could just try the experiment yourself.
Does anybody know the formula for endothermic reaction and exothermic reaction?
An endothermic reaction absorbs heat from its surroundings, while an exothermic reaction releases heat to its surroundings. The general formula for an endothermic reaction is: reactants + heat → products, and for an exothermic reaction: reactants → products + heat.
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.

What is a type of chemical reaction where the energy of the products is less than the energy of the reactants?
An exothermic reaction is a type of chemical reaction where the energy of the products is less than the energy of the reactants. This means that energy is released during the reaction in the form of heat or light. Examples include combustion reactions and many neutralization reactions.
Is baking bread a endothermic and exothermic?
Sounds like a homework question. We know that in an exothermic reaction, heat is taken out of the system and given to the surroundings. Whereas in an endothermic reaction, heat is pulled from the surroundings into the system. I am assuming you are thinking of the cookies as the system. So in this case, energy--in the form of heat--is being taken out of the oven and being put into the cookies. The cookies, using the energy increase in temperature, which bakes the cookies, creating the tasty little morsels of joy that cookies are.
How do you know if an enthalpy change diagram is endothermic or exothermic?
If you plot the reaction coordinate (what I think you mean by "enthalpy change diagram"), the reaction will be exothermic if the products are lower on the graph than the reactants. If they are higher than it is endothermic. For instance, if you go to the linked Wikipedia page (link to the left of this answer), the graph shown is of an exothermic reaction.
Where are endothermic and exothermic reaction used in industry?
Endothermic reactions are used in industries like pharmaceuticals for drug synthesis and in metallurgy for metal extraction. Exothermic reactions are commonly used in industries like power generation for fuel combustion and in chemical manufacturing for producing heat as a byproduct.

Is endothermic energy occurring when crystals dissolve in water and the container gets hot?
No.I know that in endothermic reactions things absorb heat or get colder. In exothermic reactions they release heat or get warmer. So, since the container gets hot I guess the energy is exothermic.
