What is the word used to describe a chemical reaction in which energy is released?
Any chemical reaction that releases energy is called an exothermic action. The equations for an exothermic reaction between substance A and substance B would be:
A + B --> AB + Heat
The heat represents the energy and we can tell it is being released because it is on the product side of the equation. The reverse reaction would be endothermic, meaning it requires energy, heat would be on the reactant side and the equation would be:
AB + Heat --> A + B
To sum things up, an exothermic reaction releases energy and heat will be on the product side of the equation. An endothermic reaction requires energy and heat will be on the reactant side of the equation.
What else can I help you with?
True or false when a bond is broken in a chemical reaction heat energy is released?
It is true that when bonds are broken there is chemical reaction. Then heat energy is released.
What is a unit of energy that can identify the amount of energy released or absorbed by a chemical reaction?
The unit of energy commonly used to identify the amount of energy released or absorbed by a chemical reaction is the kilojoule (kJ).
Does energy decrease or increase during a chemical reaction?
Energy can either decrease or increase during a chemical reaction depending on whether it is an exothermic reaction (energy is released) or an endothermic reaction (energy is absorbed). In an exothermic reaction, energy is released in the form of heat, and in an endothermic reaction, energy is absorbed from the surroundings.
Chemical potential energy in a sentence?
Chemical potential energy is the energy stored in the chemical bonds of a substance that can be released during a chemical reaction.
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.
Which type of energy is released in chemical?
Chemical energy is released during a chemical reaction.
What is the difference between a exothermic chemical reaction and a endothermic chemical reaction?
energy released by the reaction or energy absorbed.
Is chemical energy released during a chemical reaction?
exothemic energy
What is the best term to describe a chemical reaction that absorbs heat energy?
An endothermic reaction.
Can energy be taken in a chemical reaction?
Depending on the particular chemical reaction, energy may be either released or absorbed.
What is the chemical reaction role of energy?
energy is released or absorbed.
Energy is what in a chemical change?
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.
True or false when a bond is broken in a chemical reaction heat energy is released?
It is true that when bonds are broken there is chemical reaction. Then heat energy is released.
Energy is released when?
For example in an exothermic chemical reaction.
What is a unit of energy that can identify the amount of energy released or absorbed by a chemical reaction?
The unit of energy commonly used to identify the amount of energy released or absorbed by a chemical reaction is the kilojoule (kJ).
When is energy released during a a chemical reaction?
When chemical bonds form
When energy released during a chemical reaction?
When chemical bonds form
