What else can I help you with?
What chemical reaction produces the sun and energy?
These are not chemical reactions but thermonuclear reactions.
What energy is in chemical reactions?
Chemical energy
What was the source of energy in miller-ureys experiment?
The source of energy in the Miller-Urey experiment was a spark discharge, simulating lightning, which was used to provide energy to drive chemical reactions in their simulated early Earth atmosphere.
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.
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.
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.
Why do reactions always involve a change in energy?
Chemical bonds always break in chemical reactions, causing changes in energy.
