What takes place when a chemical reaction releases energy?
Chemical bonds are broken.
The body releases energy by respiring (respiration) Respiration is the chemical reaction of which your body makes energy from the food in our cells in our body There are two types of respiration; Aerobic Respiration - This type releases energy from food The equation for this is - Glucose + Oxygen -----> Carbon Dioxide + Water + ENERGY Anaerobic respiration - also releases energy from food, But this produces Lactic acid and energy instead The…
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is a Exothermic b Reactant c Balanced d Endothermic?
Activation energy is the minimum energy that reactant particles must possess in order for the chemical reaction to occur. That is defined as the energy that must be overcome in order for a chemical reaction to occur. Activation energy may also be defined as the minimum energy required to start a chemical reaction. It is the amount of energy required for a chemical reaction to take place. This is why some chemical reactions require heat…
Energy is the key for any reaction to take place. To break the bonds of a substance, a fixed amount of energy is required which is called bond energy. For some substances the bond energy is low and they do not require external energy and start reaction on their on there own whereas for some substances we have to provide external energy for the reaction to take place.
Energy is neither created nor destroyed in a chemical reaction Explain where the energy released or absorbed by the reactions comes from or goes to?
Energy released by a chemical reaction is released as heat to the surroundings thus rising the temperature of the room or lab etc where the reaction is taking place. Similarly, energy absorbed by endothermic is either supplied by external heating of reaction mixture over a flame or absorbed from surroundings.
