Is the reaction 2Fe plus 3O2 Fe2O3 endothemic or exothemic?

The reaction 2Fe + 3O2 → Fe2O3 is exothermic. In this process, iron reacts with oxygen to form iron(III) oxide (rust), releasing heat in the process. Exothermic reactions are characterized by the release of energy, typically in the form of heat, which occurs in this reaction as iron oxidizes.


What is the difference between endothemic and exothemic?

The terms "endothermic" and "exothermic" refer to whether a chemical reaction absorbs or releases heat, respectively. In an endothermic reaction, heat is absorbed from the surroundings, while in an exothermic reaction, heat is released into the surroundings.


What indicates that an exothemic chemical reaction occurs when two substances are mixed together?

Exothermic reactions release heat energy, so they would produce heat (increase in temperature). This can easily be tested by touching the container with your hands, or by using a thermometer. The opposite is an 'endothermic' reaction, which absorbs energy and feels colder.


Can one of this symbol h between endotheic and exothemic?

The symbol ( h ) typically represents enthalpy in thermodynamics. In the context of endothermic and exothermic reactions, it can be associated with changes in enthalpy. An endothermic reaction absorbs heat, resulting in a positive change in enthalpy (( \Delta h > 0 )), while an exothermic reaction releases heat, leading to a negative change in enthalpy (( \Delta h < 0 )). Therefore, while ( h ) itself is not inherently endothermic or exothermic, its change (( \Delta h )) indicates the nature of the reaction.


How does the energy of a substance change during an exothermic change?

During an exothermic change, energy is released from the substance in the form of heat to the surroundings. This results in a decrease in the internal energy of the substance, leading to a decrease in its temperature.

Is the reaction between sodium bicarbonate and HCL edothermic or exothemic?

The reaction between sodium bicarbonate and hydrochloric acid is exothermic, meaning it releases heat. This is evident by the increased temperature observed when the two substances are mixed together.

What is the balance equation for the reaction sodium hydroxide with water in an exothemic reaction?

When solid sodium hydroxide dissolves in water, the water heats up, demonstrating that the process of dissolving is exothermic for NaOH. (Very exothermic, in fact, releasing about 45kJ of heat per mole dissolved -- enough to heat a liter of H2O by 10C!) Since heat can be thought of as a product in an exothermic reaction, the equation is: NaOH (s) ---> Na+ (aq) + OH_ (aq) + 45kJ

Is a liquid endothermic or exothemic?

A liquid on its own cannot be described as either endothermic or exothermic. The terms endothermic and exothermic are the names of two opposite process reactions. An endothermic reaction absorbs heat and and exothermic reaction gives off heat. A liquid can be involved in either an endothermic reaction or in an exothermic reaction. If you are evaporating a liquid from its liquid phase to its gas phase, then the reaction is usually endothermic and vice versa, going from the gas phase to the liquid phase, the reaction is usually exothermic.

If the reaction gets hot is it an endothermic or an exothermic reaction?

The reverse reaction is not always endothermic or exothermic, the reverse reaction is the opposite of whatever the initial reaction is, so if the reaction is endothermic, the reverse reaction is exothermic and vise versa.


Is rusting of iron an endothermic process?

According to the definition of an exo/endo-thermic compound, all metallic oxides (rusty metals) are exothemic compounds, since their forming reaction starting from elemenets (Me + O2) is called rusting as an example of an exothermic reaction.
