Can energy be released during chemical reaction can it be absorbed can chemical reaction take place in which energy is neither absorbed or released?

Answer 1

The simple ANSWER IS yes!!! The reaction that does this is referred to as 'Exothermic'.

Energy can be absorbed during a chemical reacton, but it needs an activation energy to start the reaction.

For all chemical reactions there is always a change of energy. No reaction is ever 'energy less'. However, the exchange of energy can be very small.

Example of an exothermic reaction is sulphuric acid and sodium hydroxide. if you hold the beaker the two reactants are in , it will feel warm. This is an exothertmic reaction.

For the thermal decomposition of calcium carbonate, you have to heat it up; you are driving energy in, so it is an endothermic reaction. Other endo thermic reactions, may feel cold, they are absorbing heat at ambient room temperature.

Answer 2

During a chemical reaction, energy can be either released or absorbed, depending on the specific reaction and the overall energy balance. Let's explore these possibilities:

Exothermic Reactions: In an exothermic reaction, energy is released into the surroundings. The reactants have a higher energy state than the products, and the excess energy is released as heat or light. Examples of exothermic reactions include combustion reactions, such as the burning of fuels like gasoline, where energy is released as heat and light.

Endothermic Reactions: In an endothermic reaction, energy is absorbed from the surroundings. The reactants have a lower energy state than the products, and energy is required for the reaction to proceed. This energy is typically absorbed as heat from the surroundings. An example of an endothermic reaction is the process of photosynthesis, where energy from sunlight is absorbed by plants to convert carbon dioxide and water into glucose and oxygen.

Energy-Neutral Reactions: In some cases, a chemical reaction can occur where there is no net release or absorption of energy. These reactions are called energy-neutral reactions. Although individual bonds may be broken and formed during the reaction, the overall energy balance remains unchanged. An example of an energy-neutral reaction is the interconversion of an isomer into another isomer, where the same amount of energy is required to break and form bonds.

It's important to note that energy is always conserved in a chemical reaction according to the law of conservation of energy. The total energy of the reactants is equal to the total energy of the products, even if there is a release or absorption of energy during the reaction.

Answer 3

I apologize for the confusion earlier. Since you have not provided any specific information about the reactions you are referring to, I'll provide some general examples of reactions and their products:

1. Combustion reaction:

   Reaction: Fuel (e.g., hydrocarbon) + oxygen -> carbon dioxide + water + energy

2. Acid-base reaction:

   Reaction: Acid + base -> salt + water

3. Precipitation reaction:

   Reaction: Soluble salt + soluble salt -> insoluble salt (precipitate) + aqueous solution

4. Redox reaction:

   Reaction: Oxidizing agent + reducing agent -> oxidized product + reduced product

Please keep in mind that these are just general examples, and specific reactions may have unique reactants and products. If you have a particular reaction or category of reactions in mind, I will be happy to help with more

Answer 4

Yes, released energy does create a chemical reaction in most cases (I am a 7th grader so I dont know what really happens just that something happens. I do know that chemical reactions give off released energy. Take fire for example, it is a chemical reaction and is releasing energy (which in this case is heat).

Answer 5

to be honest with you, i don't know. but i think i can make a good point that it would seem that if no energy is released or absorbed, i cant imagine a change/reaction taking place at all, so i say NO!

Answer 6

A chemical reaction that absorbs energy will occur even without a source of energy. The endergonic reaction will be used to activate energy.

Answer 7

yes it does change when matter takes place in which energy is neither released nor absobed .

Answer 8

no it can not :)

Answer 9

no

Answer 10

Yes.
