Endothermic and exothermic reactions are similar in that both have reactants and products. They are different in that exothermic reactions release energy through reacting and endothermic reactions absorb it.

∙ 13y agoEndothermic reactions and Exothermic reaction are never the same.
They are both different.
Definitions
- Endothermic:- reactions that take in energy. For example:- electrolysis, thermal decomposition and the reaction between ethanic acid and sodium carbonate.
- Exothermic:- reactions that transfer energy to the surroundings. For example:- burning, neutralisation and the reaction between water and calcium oxide.

∙ 13y agoBoth are type of chemical reactions but the basic difference lies in the energy.
In an endothermic reaction, energy has to be given from external source to make the reaction occur but in case of exothermic reaction, heat is evolved as products are formed.
Also, in former case the reactants are more stable as compared to products whereas in latter case the products are more stable.

How do endothermic and exothermic reactions work together to supply energy?

What chemicals react to make a hot pack hot?
Yes, hot packs have exothermic reactions (the contents create heat) and cold packs have endothermic reactions (they require heat to occur, therefore making the surroundings colder). In hot packs its a reaction between water and a salt solution, and in cold packs its normally water and ammonium nitrate. peeace
How does light dependent and light independent reaction work together?
The Light Reactions Provide Energy Carriers For The Dark Reactions.
Why is work positive in an exothermic reaction?
kind of depends on the reaction. ex. solid and a liquid react causing a an aqueous solution and a gas to form. when a gas is formed the gas expands causing it to do work on its surroundings causing work to be negative.
What is used in a lab to carry out reactions?
Chemical reactions occur everywhere - your brain, stomach, liver, kidneys. No single organ does all the work.

How can endothermic and exothermic reactions work?
they work together by producing more heat or thermal energy.
How can endothermic and exothermic reactions work together?
they work together by producing more heat or thermal energy.
What is an another name for exothermic and for endothermic reactions?
it is a Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive. There are other chemical reactions that must absorb energy in order to proceed. These are endothermic reactions. Endothermic reactions cannot occur spontaneously. Work must be done in order to get these reactions to occur. When endothermic reactions absorb energy, a temperature drop is measured during the reaction. Endothermic reactions are characterized by positive heat flow (into the reaction) and an increase in enthalpy (+ΔH).
What is endothermic and exothermic reaction?
Endothermic; that reaction in which energy is absorbed is called endothermic reaction, mostly the breaking of a molecule is an endothermic reaction, as for breaking process energy is required, when a molecule gets the sufficient energy it breaks. EXOTHERMIC Reaction is that in which energy is released, as combining of any two element or atoms to make a molecule, take the example of formation of CO2.
Does gas expand under pressure and does it release energy into the environment?
I believe you are describing endothermic and exothermic reactions. An endothermic reaction is work done on the system by the surroundings. For example, gas engines- the cylinder does work on the gas/oxygen mix and in internally stores the energy until it is combusted, by means of a spark plug to form CO sub 2 and HOH (i.e. water). exothermic reactions, however, are those which are work done by the system on the surroundings. Any combustion reaction is an exothermic reaction.
What is the name given to a reaction the gives off energy?
A reaction that gives off energy is an exothermic reaction. The reaction will give off energy in the form of either heat or light An example of an exothermic reaction would be the curing of concrete. One chemical reaction that will give off heat is the mixture of Caustic Soda and water. The water dissolves the Caustic Soda which in turn generates heat. There are two types of reactions. Exothermic reactions give off heat, and endothermic reactions require that heat be added to make them work. Be careful with exothermic reactions. A rapid, energetic exothermic reaction is called an "explosion".
A sign that a chemical reaction is taking place is release of energy in the form of?
Most common chemical reactions are exothermic. This means that when the reaction occurs, they release heat. Some reactions are endothermic, which means they absorb heat.
What type of reaction is it when energy is released?
Exothermic, generally. Exo- is out, -thermic refers to heat energy. You could have an endothermic reaction with other energy released, say radiation or work, but it is less common.
What doe endothermic mean?
Endothermic means, literally, "within-heating". It is usually used in reference to chemical reactions and is used to describe a chemical reaction that absorbs heat from its surroundings to create chemical bonds. A good way to tell if a reaction is endothermic or not is to feel the outside of the container it is in (cautiously!). An endothermic reaction feels cool to the touch. This is how those cold packs that don't need to be refrigerated work.
How does self cooling work?
with endothermic reaction
What is the standard enthalpy of formation for butane?
the standard enthalpy change of vaporization DHov is the enthalpy change when one mole of a substance is transformed into a gas enthalpy change is the term we use to describe the energy exchange that occurs with the surroundings at a constant temperature and pressure so to work it out, use the formula DH = cmDT DH - the enthalpy change c - the specific heat capacity of butanol (kJ kg-1 °C-1) m - the mass of butanol heated (kg) DT - the change in temperature of the butanol (°C) so there is no general enthalpy change of butanol, it depends on the factors above. the specific heat capacity of butanol, the mass of butanol heated, and the change in temperature of the butanol should be given to you in order to work the enthalpy change of vaporization of butanol if there is a rise in temperature, the reaction is exothermic and if there is a drop in temperature the reaction is endothermic. exothermic reactions have a negative enthalpy change, and therefore endothermic reactions have a positive enthalpy change. hope it helped (:
