Endothermic reactions absorb heat from their surroundings, resulting in a decrease in temperature in the room where the reaction takes place. This can make the room feel cooler as the reaction uses up the heat energy present in the environment.

How can an endothermic reaction be spontaneous at room temperature?

An endothermic reaction can be spontaneous at room temperature if the increase in entropy of the system is large enough to overcome the energy input required for the reaction. This can happen if the products of the reaction have higher entropy than the reactants. As a result, the overall change in free energy can be negative even though the reaction is endothermic.


Is melting of iron in furnace exothermic?

Neither endothermic nor exothermic. These two terms apply to chemical reactions, wether they require or produce energy (heat). Melting iron isn't a chemical but a physical reaction, a change of phase, solid to liquid. Iron is solid at room temperature, we heat it to melt it, so heat is added (which is the same as the principle of endothermic, heat is absorbed, it must be heated)


What suubstance will react with water at room temperature and pressure to produce hydrogen?

Sodium reacts with water at room temperature (even at lower ) and produce hydrogen gas , 2Na + 2H2O = 2NaOH + H2


Why melting ice is considered an endothermic reaction?

False.The original answer (now deleted ) said that the melting of ice is an endothermic reaction.If you need to convince yourself of this, take half a glass of water at room temperature. Put in a thermometer, wait a while, then record the temperature.Now add a few ice cubes; wait a while, then check the temperature again. If the melting of ice were an exothermic process, the water would then be warmer. Since you will actually find the water to be cooler, it is an endothermic process.


What material has the chemical formula SO3?

Sulfur trioxide (SO3) is a chemical compound that is a colorless, volatile liquid at room temperature. It is commonly used in the production of sulfuric acid and as a strong oxidizing agent in various chemical reactions.

Does the temperature of a room affect how fast a candle melts?

The room temperature is too low for an effect.


Is energy alwways released during a chemical change?

No. Chemical changes can release heat (exothermic) or absorb heat (endothermic). The change in molecular structure determines whether energy is stored or released. Example of exothermic : * combustion of paper (oxidation, releasing carbon bond energy) * acetic acid (vinegar) accelerates the oxidation of steel wool (rusting) Example of endothermic : * Combination of citric acid and baking soda : temperature of the mixture shows a definite drop before rewarming by room temperature air. * In a commercial "Cold Pack", the chemicals mix and absorb heat. There are reactions which require an activation energy before proceeding to an exothermic change. This is demonstrated by the common matchstick.


Will the temperature of the lemon juice affect the pH levels?

Yes, temperature can affect the pH of lemon juice. As temperature increases, the chemical reactions in the lemon juice can be altered, which may change the pH level. Generally, warmer temperatures can decrease the pH of lemon juice.


How does the temperature affect how well dough rises?

It has to be room temperature for the dough to rise.


The synthesis of carbon disulfide is spontaneous and exothermic at room temperature what must be true regarding this reaction?

The reverse reaction is endothermic and nonspontaneous.


Chemical reactions will occur independently of the reactant's temperature?

Chemical reactions can be temperature-dependent. Generally, increasing temperature can increase the rate of a reaction by providing more energy for molecules to react. However, there are exceptions and some reactions can occur at room temperature or even at lower temperatures.

Is liquid exothermic or endothermic?

Depends, Liquid can be both endothermic and exothermic, for example water, if you freeze water and put it in room temperature it will be endothermic, meaning it will absorb the heat form the room. And if you Boil water and put it in a cold place it will become exothermic because its releasing the heat.
