The most important endothermic reaction is photosynthesis, where plants use sunlight to convert carbon dioxide and water into glucose and oxygen. This process is essential for producing oxygen, removing carbon dioxide from the atmosphere, and providing energy for plants and other organisms in the food chain.

Is photosynthesis an exothermic or endothermic reaction?
Photosynthesis is an endothermic reaction because it requires energy from sunlight to convert carbon dioxide and water into glucose and oxygen. This process absorbs energy rather than releasing it.
What is endothermic use in a sentence?
Endothermic reactions absorb heat from their surroundings to proceed, causing a decrease in temperature. An example of an endothermic reaction is photosynthesis in plants, where energy from sunlight is used to convert carbon dioxide and water into glucose and oxygen.
Are endothermic reactions always nonspontaneous?
No, many exothermic reactions need the heat of activation to start the reaction. Paper, for instance, does not spontaneously burst into flame... you need to raise its temperature to the kindling point for it to burn.
Is boiling of water am endothermic or exothermic?
Yes boiling water is endothermic because you are supplying the energy to the water molecules. (Or in most instances the kettle is supplying the energy to the water, still endothermic), the water doesn't just spontaneously boil at 25C and release heat energy, it takes you putting in massive energy to get it to boil.
Is the melting of candle wax and exothermic or endothermic change?
The melting of candle wax is an endothermic change because it absorbs energy from its surroundings to break the intermolecular forces holding the wax molecules together. This energy is needed to overcome the attraction between molecules and change the wax from a solid to a liquid state.
Is photosynthesis an exothermic or endothermic reaction?
Photosynthesis is an endothermic reaction because it requires energy from sunlight to convert carbon dioxide and water into glucose and oxygen. This process absorbs energy rather than releasing it.
What is the type of chemical reaction in which heat energy is absorbed?
An endothermic reaction is a type of chemical reaction in which heat energy is absorbed from the surroundings. This results in a decrease in temperature of the surroundings and an increase in the energy of the reactants.
Is the reaction between x which forms X2 exothermic or endothermic?
Most normally this 2X --> X2 reaction is exothermicbut it is not a general rule.
What is the worlds most important mammal?
a person
A chemical reaction that gives off heat is most likely to be what?
An exothermic reaction is a chemical reaction that gives off heat. In an exothermic reaction, energy is released in the form of heat to the surroundings.
When your body metabolizes food is it endothermic?
No, in most cases it isn't endothermic. Metabolism, based on the Krebs Cycle, is a biochemical reaction which creates Adenosine Triphosphate, also known as ATP and Energy. Energy is in fact exothermic.
When ammonium chloride mixes with water the solution formed feels cold what type of reaction is this endothermic or exothermic?
This reaction is endothermic because it requires the absorption of heat from the surroundings to break the bonds between the particles of ammonium chloride and water. This absorption of heat results in a feeling of coldness in the surroundings.
Are all thermal decomposition reactions endothermic in nature?
No, not all thermal decomposition reactions are endothermic. Some decomposition reactions can be exothermic, meaning they release heat energy instead of absorbing it. The endothermic or exothermic nature of a decomposition reaction depends on the specific compounds involved and their energy changes during the reaction.
Why was Pope John Paul II important?
Because he was recognised as the worlds most religious leader
A chemical reaction that transfers energy from the reactants to the surroundings is reffered to as?
A chemical reaction that transfers energy from the reactants to the surroundings is referred to as an exothermic reaction. A reaction that takes energy in is endothermic.
What is the worlds most important regional economic group?
European Union (EU)
Which waterway is one of the worlds most important shipping routes?
suez canal
