Is photosynthesis an exothermic or endothermic reaction?
Yes photosynthesis is a endergonic process i.e. energy-requiring process.
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 answer is endothermic. The wax is absorbing heat energy, not producing it, and changing from a solid state to a liquid state. If the reactants require more energy than than they are putting out during the reaction, it is said to be endothermic (absorbing of heat). If the reactants give off heat of their own (self sustaining), then it is an exothermic reaction. There are components in some types of wax that will burn, in which case that is an example of an exothermic reaction, but most wax will stop once the heat source is removed.
Is burning of wood a endothermic change?
nope. Endothermic reactions involve the reactants including heat, but ending up with colder products. But you started with wood without heat, and ended up with a hot fire. This is an exothermic reaction.
How do you use the word endothermic in a sentence?
Most endothermic reactions will stop once the temperature becomes too low. Stars cannot make energy from fusing iron into nickel since it is an endothermic process.
Is photosynthesis an exothermic or endothermic reaction?
Yes photosynthesis is a endergonic process i.e. energy-requiring process.
A chemical reaction that gives off heat is most likely to be what?
An endothermic reaction is one that consumes heat.
What is the type of chemical reaction in which heat energy is absorbed?
Endothermic reactions.Endo- means 'inside' which is where the energy ends up.Exothermic reactions give off energy. Exo- means 'outside'. Think that a spider sheds an 'exo'skeleton, or a skin on the outside.
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
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?
When ammonium chloride dissolves in water, it is not a reaction at all, but only a dissolution. Since the solution formed feels cold, the dissolution is endothermic, absorbing heat from its surroundings.
Is sweating a chemical reaction?
Oddly enough, evaporation is endothermic. To tell the difference, simply ask yourself, must heat be added or taken away for a phase change to occur. If heat must be added it is endothermic, if heat must be taken away it is exothermic. In the case of evaporation in most cases you must raise the temperature for a substance to evaporate, thus it is endothermic.
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 are the body decomposition reaction?
The most important body decomposition reaction is the digestion of foods.
What is the most important chemical reaction of all?
Photosynthesis
