Why photosynthesis called endothermic reaction?
Photosynthesis is an endothermic reaction because it takes energy (from sunlight) from the environment to use in the photosynthesis reaction. Without the energy input, the photosynthesis reaction could not occur.
Chemical changes release energy?
Chemical changes can either absorb or release energy. When a chemical reaction releases energy, it is called an exothermic reaction. This means that the products of the reaction have lower energy than the reactants, and the excess energy is released in the form of heat or light.
What is the reaction between butane and oxygen called?
The reaction between butane and oxygen is called combustion. This reaction produces carbon dioxide and water vapor as products, releasing energy in the form of heat and light.
What type of reaction is S8 8O2 8SO2 energy?
The reaction of sulfur and oxygen to produce sulfur dioxide is called combination or synthesis.
How energy generated by chemical reaction is converted into light energy?
When a chemical reaction occurs, energy is released in the form of light through a process called chemiluminescence. This occurs when the reactants in the chemical reaction convert their energy into excited electronic states, which then release energy in the form of photons (light) as they return to their ground state. This phenomenon is commonly seen in glow sticks and fireflies.
A chemical reaction that absorbs energy in the form of heat is called?
Endothermic reaction
What is a reaction that releases energy in the form of heat is called a?
kinosis
Energy needed to kick start a reaction is called what?
The energy needed to kick start a reaction is called activation energy. It is the minimum amount of energy required for a chemical reaction to occur. It is usually provided in the form of heat or light energy.
A change of state in which energy is removed from a substance is called an?
A change of state where energy is removed from a substance is called an exothermic reaction. This chemical reaction releases energy in the form of light or heat.
When a chemical reaction absorbs energy in the form of heat is called a?
Endothermic reactions.
A reaction that releases energy in the form of heat?
An exothermic reaction releases energy in the form of heat. This type of reaction typically results in a rise in temperature in the surrounding environment. Examples include combustion and neutralization reactions.
Chemical reaction that releases energy?
All chemical reactions that release energy in the form of heat are called exothermic reactions.
Why photosynthesis called endothermic reaction?
Photosynthesis is an endothermic reaction because it takes energy (from sunlight) from the environment to use in the photosynthesis reaction. Without the energy input, the photosynthesis reaction could not occur.
In what form is the energy released in this reaction?
In an exothermic reaction heat energy is released.
What is the chemical energy needed for reactants to form products called?
The chemical energy needed for reactants to form products is called activation energy. This energy is required to initiate a chemical reaction by breaking bonds in the reactants.
Energy is lost from a reaction in a form of what?
Energy is lost from a reaction in the form of heat. This heat is often referred to as exothermic heat, as it is released from the system during the reaction.
Free energy is the minimum energy necessary for product to form?
Free energy is the energy that is available to do work in a system. It is calculated as the difference between the enthalpy and the product of the temperature and entropy of a reaction. In a chemical reaction, the free energy change (ΔG) determines whether the reaction is spontaneous (ΔG < 0) or non-spontaneous (ΔG > 0).
