There are many reactions in which the enthalpy of the is changed after the formation of the product and the enthalpy change could be negative or it could be positive. The change in enthalpy depends on the type of reaction that it is an exothermic reaction or it is an endothermic reac...

What is an endothermic reaction?Reactions:In science, there are all kinds of reactions and each reaction involves the exchange of something. Chemical reactions, for example, exchange molecules to either help separate or make new compounds.Answer and Explanation: ...
energy is released as heat, the process is exothermic, and when heat is absorbed, the process is endothermic. An endothermic reaction is one which results in a net decrease in temperature because it absorbs heat from the surroundings and stores the energy in the bonds formed in the reaction....
ergic) nuclear reaction is areaction that releases energywhile an endothermic (or endoergic) reaction is one that requires an input of energy to take place. ... If the reaction energy is positive, the reaction is exothermic but if the reaction energy is negative, the reaction is endothermic....
Exothermic vs. Endothermic Here is how to classify the phase changes as endothermic or exothermic: Phase Change Name:Freezing •Phase: Liquid to solid •Energy Change: Exothermic •Example: Freezing water Phase Change Name:Melting •Phase: Solid to liquid ...
What is enthalpy of reaction? What is heat of precipitation? What is heat of displacement? What is the enthalpy of neutralization? What is the heat of combustion? Why is energy released when a bond is formed? Applications of exothermic and endothermic reactions in everyday life ...
