What chemical reaction produces the sun and energy?
These are not chemical reactions but thermonuclear reactions.
Describe the role of energy in chemical reactions?
Chemical reactions that release energy often occur spontaneously. Chemical reactions that absorb energy will not occur without energy.
What energy is in chemical reactions?
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.
Is chemical energy a source of electricity?
no, chemical energy is the energy released from chemical reactions
Chemical reactions that require energy?
endothermic reactions require energy
Why do chemical reactions always involve a change in energy?
Chemical bonds always break in chemical reactions, causing changes in 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.
Reaction the reales energy are called?
The general term for a chemical reaction that releases heat is an exothermic reaction.
Which term describes energy that is required to get chemical reactions started?
Activation energy describes the energy that is required to get chemical reactions started.
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.
When chemical reactions occur energy is always absorbed?
No, chemical reactions can be endothermic or exothermic.
