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.
Is a reaction that gets hot exothermic or endothermic?
A reaction that gets hot is exothermic because it releases heat to the surroundings. This means that the products have less energy than the reactants, resulting in a negative change in enthalpy.
Endothermic and exothermic reaction?
An exothermic reaction releases energy, usually to the surroundings. There is a net loss of energy from the reactants. However, exothermic reactions also need a little energy to get started, but this is less than the eventual amount given out. An endothermic reaction takes in energy, also usually from the surroundings. There is a net gain of energy into the reactions. Again, a little energy is lost, but this is hardly anything compared to the amount taken in.
What is the difference of endothermic reaction from exothermic reaction?
Endothermic reactions absorb heat from their surroundings, resulting in a decrease in temperature, while exothermic reactions release heat to their surroundings, causing an increase in temperature. In endothermic reactions, the products have more energy than the reactants, whereas in exothermic reactions, the products have less energy than the reactants.
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.

What are differences between endothermic and exothermic reactions examples?
The main differences between exothermic reactions and endothermic reactions are: Exothermic reactions are reactions that give off energy (light, electrical or mainly heat), causing the surroundings to warm up. Endothermic reactions are reactions that absorb energy, causing the surroundings to cool down. The products of an exothermic reaction have less energy, or less total enthalpy, than of it's reactants. This is due to the reactants containing more stored energy because energy from external sources is not required. This also gives the products more stability because in order to achieve a reversible reaction and break the chemical bonds of the products, you will need to apply more energy to it. The opposite is for endothermic reactions. The products of the reaction have a greater total enthalpy of the reactants, causing the reactants stored energy to decrease. This produces less stable products that need less energy to break their bonds in a reversible reaction. Finally most exothermic reactions are spontaneous, where as most endothermic reactions are not spontaneous as they generally need energy applied to them before they start.
What is a type of chemical reaction where the energy of the products is less than the energy of the reactants?
An exothermic reaction is a type of chemical reaction where the energy of the products is less than the energy of the reactants. This means that energy is released during the reaction in the form of heat or light. Examples include combustion reactions and many neutralization reactions.
When energy released or absorbed?
Energy is released when a chemical reaction is exothermic, meaning that the products have less energy than the reactants. Energy is absorbed in an endothermic reaction, where the products have more energy than the reactants.
How does the energy required for dissolving the solute compare with the energy released?
When a solute dissolves in a solvent, energy is required to break the intermolecular forces between solute particles, which is an endothermic process. This energy input must be compared to the energy released when new interactions form between the solute and solvent molecules, which is an exothermic process. If the energy released during solvation exceeds the energy required to break the solute's intermolecular forces, the overall process is exothermic and favorable. Conversely, if more energy is required to dissolve the solute than is released, the process is endothermic and may be less favorable.
What type of reaction is it when energy is released?
Exothermic, generally. Exo- is out, -thermic refers to heat energy. You could have an endothermic reaction with other energy released, say radiation or work, but it is less common.
What happens to the reaction during endothermic and exothermic reaction?
During an endothermic reaction, heat is absorbed from the surroundings, causing the reaction to feel cold. The reactants have less energy than the products, so energy is absorbed to form the products. In an exothermic reaction, heat is released into the surroundings, making the reaction feel hot. The reactants have more energy than the products, so energy is released during the reaction.
Is bond making exothermic or endothermic?
Bond making is typically exothermic, meaning energy is released when chemical bonds are formed. This is because forming bonds allows atoms to achieve a more stable and lower energy state than when they are separate.
