In chemical reactions, energy is either released (exothermic) or absorbed (endothermic). Energy input is required to break bonds in reactants, and energy output is released when new bonds form in products. The difference between energy input and output determines if a reaction is exothermic or endothermic.
What else can I help you with?
How is exothermic reactions related to chemical energy?
Heat energy is directly related to chemical interactions. As heat energy increases, chemical interactions also will due to the increased kinetic energy and therefore interactions of particles.
Describe the role of energy in chemical reactions?
Energy is required to break bonds between atoms in reactant molecules, allowing them to rearrange into new products. This energy is called activation energy. Some reactions release energy, called exothermic reactions, while others absorb energy, called endothermic reactions. Overall, energy is essential for driving chemical reactions and determining whether they proceed or not.
Why energy is necessary to chemical reactions and describe some common sources of energy.?
Energy is necessary for chemical reactions because it allows molecules to overcome activation energy barriers and initiate reactions. Common sources of energy for chemical reactions include heat, light, electricity, and catalysts. These sources provide the necessary energy to break existing bonds and form new ones during a chemical reaction.
What is the role of a propane bond in chemical reactions?
The role of a propane bond in chemical reactions is to provide a source of energy that can be released when the bond is broken. This energy can then be used to drive other chemical reactions or processes.
Do polar or nonpolar bonds have more energy in chemical reactions?
Polar bonds have more energy in chemical reactions compared to nonpolar bonds.
What are 4 forms of energy related to changes in matter?
Thermal EnergyChemical EnergyElectromagnetic EnergyElectrical Energy
What chemical reaction produces the sun and energy?
These are not chemical reactions but thermonuclear reactions.
What energy is in chemical reactions?
Chemical energy
How is exothermic reactions related to chemical energy?

What reactions convert light energy to chemical energy?
The light dependent reactions take in the light energy and convert that to chemical energy, but it is in the Calvin cycle (light independent reactions) where the chemical energy is stored in a complex sugar.
Chemical reactions that require energy?
endothermic reactions require energy
WHAT TERM DESCRIBES ENERGY THAT REQUIRES TO GET CHEMICAL REACTIONS STARTED?
Activation energy describes the energy that is required to get chemical reactions started.

Do chemical reactions transfer energy?
Yes, chemical reactions can transfer energy in the form of heat or light. Exothermic reactions release energy in the form of heat, while endothermic reactions absorb energy from their surroundings.
What term describes energy that is required to get chemical reactions started?
Activation energy describes the energy that is required to get chemical reactions started.
Why do nuclear reactions release more energy than chemical reactions?
Nuclear reactions release more energy than chemical reactions because they involve changes in the nucleus of an atom, where much larger amounts of energy are stored compared to the energy stored in the electron shells involved in chemical reactions.
When chemical reactions occur energy is always absorbed?
No, chemical reactions can be endothermic or exothermic.
