What kind of reaction energy that requires energy in the form of heat?

Like baking a cake once you heat it, it becomes a new substance. With a chemical change you can never go back to what you had before. Also like a car rusting, a match being lite, and burning wood ( the new substance for wood is ash)

∙ 12y agowhenever a reaction takes place it either consumes energy or release energy in form of heat or light. All Exothermic reactions release energy in form of heat.
Wiki User
∙ 13y agoReactions that require energy in the form of heat are called endothermic.
Wiki User
∙ 14y agoendothermic, (so it absorbs heat instead of giving it off. Think of endo as inside of and exo outside because exothermic gives off heat making the two opposites:))
Wiki User
∙ 13y agoIt is called an exothermic reaction.
Example:
2 Na + 2 H20 ---> 2 NaOH + H2

In what form is the energy released in this reaction?
In an exothermic reaction heat energy is released.
What is A reactant in which energy is taken in?
You probably mean "what reaction releases energy," in which case, lots. Reactions that release energy into the environment are called exothermic reactions. An example of which would be mixing sodium (Na) and water (H2O) to form sodium hydroxide (NaOH), hydride (H2), and heat/energy. 2Na + 2H2O ---> 2NaOH + H2 + heat/energy
Energy is given off in the form of heat during a?
Chemical reaction.
True or false an exothermic reaction often produces energy in the form of heat light and electricity?
True
A combustion reaction occurs when a substance usually containing carbon reacts with what to produce energy in the form of heat and light?
oxygen
Energy is lost from a reaction in a form of what?
energy of a reaction will be lost in the form of heat.
A form of energy that can stimulate a reaction?
Heat energy can stimulate a chemical reaction.
What is a reaction that releases energy in the form of heat?
Exothermic reaction
What is true when two reactants combine in an exothermic reaction?
Exothermic Reactions: The delta h is always NEGATIVE! Energy is released (delta is the little triangle in front of the H)
In what form is the energy released in this reaction?
In an exothermic reaction heat energy is released.
Chemical energy is energy that is?
added to a reaction in the form of heat.
Reaction that absorbs energy in the form of heat?
Endothermic.
A chemical reaction that absorbs energy in the form of heat is called?
Endothermic reaction
If the energy released in a chemical reaction primarily in the form of heat of reaction?
yes
What reaction releases energy?
exothermic reactions release energy, like a fire, which releases heat ( also endothermic reactions requires and takes/absorbs energy for its reaction like photosynthesis which requires sunlight)
What happens to energy in an endothermic reaction?
An endothermic reaction is a reaction which requires energy. The enegry is required for the reaction to take place, maning the energy is used up in the reaction. An example of an endothermic reaction is photosythesis.
What is endothermic and exothermic?
Exothermic refers to a reaction that produces heat. When you balance the equation the energy released when new bonds are formed is greater than the energy use when bonds are broken. An endothermic reaction takes in heat as it requires more energy to break its bonds than it has from the bonds it creates.
