∙ 13y agoAn exothermic reaction is a reaction between two elements which causes the temperature to rise. The opposite is endothermic which causes the temperature to drop.

How does the energy of a substance change during an exothermic change?
During an exothermic change, such as freezing, the substance releases energy to its 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.
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.
What is the difference between endothemic and exothemic?
The difference is that the endothemic change is when energy is absorbed from the substance and exothermic change is when energy is removed or taken out of the substance.
What is the difference between normal reaction and abnormal reaction?
Normal reaction happens when the reaction is normal. Abnormal reaction happens when the reaction is abnormal.
Is chemical energy released during a chemical reaction?
exothemic energy
Is the process of celular respiration exothemic or endothermic explain your answer?
exothermic

What is energy released from chemical reactions called?
Light Energy,Electrical Energy,Light and thermal energy

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.

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
What is the difference between endothemic and exothemic?
The difference is that the endothemic change is when energy is absorbed from the substance and exothermic change is when energy is removed or taken out of the substance.
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.
What makes ice melt the fastest sugar salt pepper or sand?
SALT DOESNT MELT THE ICE IT JUST LOWERS THE FREEZING POINTWell Salt Does Make Ice Melt Faster :) I made the project and my result were correct SALT melts ice faster :)
How do you dissolve lithium hydroxide?
Very carefully! Highly exothemic dissolution reaction.Never add water to the solid material!Use all (face! and hands!) protectional measures.Add stepwise solid to the excess of water while stirring and cooling.
