Is burning a match an endothermic or exothermic change?

Burning a match is an exothermic change because energy is being released.


Is a firecracker exploding an example of an endothermic reaction or an exothermic reaction?

Exothermic Reaction because the fizzing is CO2 being released as heat (energy).


Contrast endothermic and exothermic reactions?

Endothermic reactions are chemical reactions that use heat as part of the reactant. Heat is absorbed into the reaction in order for it to continue. Exothermic reactions are chemical reactions that release heat as a product of the reaction.


Are glow sticks exothermic or endothermic glow sticks?

Glow sticks are exothermic.Exothermic is when heat/energy is released. And that is exactly what glow sticks do. but the energy being released is in the form of light.


When iron rusts is it an endothermic or exothermic reaction?

It is an endothermic reaction because in endothermic reaction energy is added .In that reaction nitrogen does not react with oxygen without energy added in the shape current . In that reaction 3000`current is applieded to take reaction b/w nitrogen and oxygen


When the temperature changes cause of a reaction is it exothermic or endothermic?

If the temperature increases during a reaction, it is exothermic. This means that heat is being released into the surroundings. If the temperature decreases during a reaction, it is endothermic, meaning heat is being absorbed from the surroundings.


What types of energy are released in exothermic reactions?

Exo -> Greek "Outside" Therm -> thérmē -> Greek "Heat" So an exothermic reaction releases heat energy. Related to that type of reaction is the endothermic reaction in which heat is absorbed into the reaction rather than being released by it.


What is the word used to describe a chemical reaction in which energy is released?

Any chemical reaction that releases energy is called an exothermic action. The equations for an exothermic reaction between substance A and substance B would be: A + B --> AB + Heat The heat represents the energy and we can tell it is being released because it is on the product side of the equation. The reverse reaction would be endothermic, meaning it requires energy, heat would be on the reactant side and the equation would be: AB + Heat --> A + B To sum things up, an exothermic reaction releases energy and heat will be on the product side of the equation. An endothermic reaction requires energy and heat will be on the reactant side of the equation.


Is magnesium ribbon burns an endothermic reaction or an exothermic reaction?

The reaction is highly exothermic as heat energy is released from the system to the surroundings whereas in endothermic the heat is absorbed from the surroundings into the system and you can also observe or see the smoke coming out of the apparatus in which the reaction is occurring or taking place.Heat energy is being released in the form of smoke.Therefore the reaction is exothermic.


Which type of reaction gives off heat?

An exothermic reaction gives off heat as a result of energy being released in the form of heat. In an exothermic reaction, the products have lower energy than the reactants, leading to the release of heat to the surroundings.


Why is energy released in a exothermic reaction?

Energy is released in an exothermic reaction because the overall energy of the products is lower than the energy of the reactants. This difference in energy levels is released as heat to the surroundings, making the reaction exothermic.


How do endothermic and exothermic differ?

Exothermic reactions release energy (usually as heat) into the surrounding environment - endothermic reactions absorb energy from the surrounding environment. Note that exothermic reactions are capable of turning into runaway reactions as the heat of reaction often speeds up the rate of reaction (releasing more heat, etc). Endothermic reactions are, usually, self moderating as a limited amount of energy is capable of being drawn from the surrounding environment.
