When do reactions that release energy happen?
The release of energy (exothermic reaction) happens when the energy release by forming the products of the reaction is greater than the energy required to break the bonds of the reactants.
What happens in a exothermic reaction?
In an exothermic reaction, the total making and breaking of bonds results in a net release of energy.
WHAT In an exothermic reaction energy is transferred from?
In an exothermic reaction energy is transferred from the system to the surroundings. An exothermic reaction is a chemical or physical reaction that releases heat.
What kind of reaction is the amount of energy needed to break the original bonds is less than the energy released when new bonds form?
What type of reaction requires less energy to break the original bonds than the energy released when new bonds form?
Which reaction occurs when energy is released?
Chemical bonds are broken.
What happens to the bonds of a chemical when there is an exothermic reaction?
they die
When do reactions that release energy happen?
The release of energy (exothermic reaction) happens when the energy release by forming the products of the reaction is greater than the energy required to break the bonds of the reactants.
How is heat from the sun an exothermic reaction?
Exos= outside , thermos=temperature or heat So within the definition itself it can be known that in exothermic reactions heat is released. In chemical reactions the energy supplied is use in breaking of bonds, but energy is release by making bonds. In exothermic reactions, the energy supplied is sufficient for chemical reaction to occur (to break existing bonds) and the excess energy is given in the form of heat (from making new bonds).If the reaction is exothermic, it means that the total energy it took to break the bonds is less than the total energy released when forming new bonds -- so net energy is released in the form of heat. for example 2H2 +O2 ----> 2H20 which is exothermic reaction. Combustion reactions in general are exothermic reactions.
What happens in a exothermic reaction?
In an exothermic reaction, the total making and breaking of bonds results in a net release of energy.
What is reactions that occur when more energy is released forming new bonds than is required to break bonds in the initial reactions?
When more energy is released than that which is provided, this is referred to as an exothermic reaction.
Is breaking bonds a exothermic or endothermic process?
The bond forming process is always exothermic.
Why is energy released in a exothermic reaction?
Energy is released in an exothermic reaction because bonds are being formed.
What is endothermic and exothermic?
Exothermic refers to a reaction that produces heat. When you balance the equation the energy released when new bonds are formed is greater than the energy use when bonds are broken. An endothermic reaction takes in heat as it requires more energy to break its bonds than it has from the bonds it creates.
WHAT In an exothermic reaction energy is transferred from?
In an exothermic reaction energy is transferred from the system to the surroundings. An exothermic reaction is a chemical or physical reaction that releases heat.
What kind of reaction is the amount of energy needed to break the original bonds is less than the energy released when new bonds form?
What type of reaction requires less energy to break the original bonds than the energy released when new bonds form?
In exothermic reactions the energy required to break the bonds in the reactants is greater than the energy released as the products form?
Exothermic reaction
Difference in exothermic and endothermic reaction?
An endothermic reaction is when the atoms break and need to abosrb heat. An exothermic reaction is whe new bonds are made and give heat to the surroundings.
