Energy is measured in joules. Sometimes the older unit "calorie" is used instead - this is a unit defined on the basis of heat, but it is still a unit of energy.
Endothermic reaction is a type of chemical reaction that absorbs energy. Energy is a property of objects.
energy released by the reaction or energy absorbed.
A chemical reaction that produces energy is said to be exothermic. In comparison, if it consumes energy it is endothermic.
Chemical energy is released during a chemical reaction.
In a chemical change, energy is either absorbed or released. When bonds are broken, energy is absorbed (endothermic reaction), and when bonds are formed, energy is released (exothermic reaction). Overall, the total energy of the system may change during a chemical reaction.
Endothermic reaction is a type of chemical reaction that absorbs energy. Energy is a property of objects.
energy released by the reaction or energy absorbed.
The energy required to start a chemical reaction is called activation energy. It is the minimum amount of energy needed to initiate a reaction by breaking the chemical bonds of the reactants. This energy barrier must be overcome for the reaction to proceed.
A chemical reaction that transfers energy from the reactants to the surroundings is referred to as an exothermic reaction. A reaction that takes energy in is endothermic.
A chemical reaction need an activation energy to start.
chemical reaction
Chemical energy is potential energy until the chemical reaction puts atoms and molecules in motion. Heat energy (KE) is often the result of a chemical reaction.
Chemical energy is typically measured in units of joules or kilojoules. This measurement is based on the amount of energy released or stored during a chemical reaction or process. Scientists use calorimetry and other techniques to measure the heat changes associated with chemical reactions to determine the amount of chemical energy involved.
Endothermic, if the energy is in the form of heat.
exothemic energy
For most chemical reactions, energy is required to supply an "activation energy" required before reaction.
A chemical reaction that produces energy is said to be exothermic. In comparison, if it consumes energy it is endothermic.
