Is 4Al 3O2 2Al2O3 exothermic or endothermic?
The reaction 4Al + 3O2 -> 2Al2O3 is exothermic. This is because it releases energy in the form of heat during the reaction. The formation of aluminum oxide (Al2O3) from aluminum (Al) and oxygen (O2) is accompanied by a decrease in enthalpy, resulting in the release of heat energy.
Is lightning a match of an exothermic or endothermic reaction?
Lightning is a result of an exothermic reaction, where energy is released in the form of light and heat. The rapid movement of electrons through the atmosphere creates the visible flash known as lightning.
Is dilution of sulfuric acid endothermic or exothermic?
The dilution of sulfuric acid is exothermic because it releases heat.
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 is the type of heat reaction which occurs when heat is given off by the reaction?
Heat is released during an exothermic reaction.
Is 4Al 3O2 2Al2O3 exothermic or endothermic?
The reaction 4Al + 3O2 -> 2Al2O3 is exothermic. This is because it releases energy in the form of heat during the reaction. The formation of aluminum oxide (Al2O3) from aluminum (Al) and oxygen (O2) is accompanied by a decrease in enthalpy, resulting in the release of heat energy.
If it get cold exothermic or endothermic?
Exothermic phenomenon
Is the breakdown of glucose endothermic or exothermic?
Exothermic. Glucose is one of the major source of energy of the body and can only act as an energy source because its breakdown into CO2 is an exothermic reaction.
What are 3 properties of carbon?
what are the 3 properties of carbon?
Is an explosion an exothermic or endothermic?
Exothermic
Is bonding endothermic or exothermic?
exothermic
Is electrolysis exothermic or endothermic?
exothermic
When energy is given off as heat the physical change is said to be?
Exothermic
Why are exothermic reactions chemical reactions?
Exothermic reactions are chemical rections since these affects the composition and chemical properties of a matter and result in the formation of new substance. Example burning of coal , electrolysis of water.
Is the combustion of hydrogen exothermic or endothermic?
The combustion of hydrogen is exothermic because it releases energy in the form of heat and light during the reaction.
Is Digestion of food -endothermic or exothermic reaction?
digestion of food release energy, so it's exothermic reaction
What is released by exothermic reactions?
Heat is released by an exothermic reaction. Exothermic means heat releasing.
