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.
How do chemical energy is transferred in to electrical energy?
Chemical energy can be converted into electrical energy through a chemical reaction in a battery. When the battery is connected to a circuit, the reaction releases electrons, which flow through the circuit as an electric current, producing electrical energy.
What type of energy is released in a glow stick?
Chemical energy is released in a glow stick through a chemical reaction between the chemicals inside the stick. This reaction produces light energy in the form of visible light.
Which type of energy is released in chemical?
Chemical energy is released during a chemical reaction.
Is energy released through chemical change?
It depends on whether or not the chemical reaction is exothermic or endothermic. If exothermic, then yes, energy is released. If endothermic, then no, energy is absorbed, not released.
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
Where in a substance is chemical energy stored?
Chemical energy is stored in the bonds between atoms and molecules within a substance. When these bonds are broken through a chemical reaction, the stored energy is released.
Can energy be taken in a chemical reaction?
Depending on the particular chemical reaction, energy may be either released or absorbed.
When chemical energy is used what happens?
Chemical energy can be "used" (ie changed from one form to another) through a chemical reaction. Energy may be released in many forms, including heat.
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.
