Reactions do not create energy; rather, they involve the conversion of energy from one form to another. In some reactions, energy is released (exothermic reactions), while in others, energy is absorbed (endothermic reactions). Energy is always conserved in a chemical reaction according to the law of conservation of energy.

What do rockets use to produce energy?
Rockets use chemical reactions, typically involving liquid or solid propellants, to produce energy for propulsion. These reactions create hot gases that are expelled through a nozzle at high speeds, generating thrust that propels the rocket forward.
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.
What does energy cause matter to do?
Energy can cause matter to change states (such as from solid to liquid), move (such as with kinetic energy), or create interactions between particles (such as in chemical reactions). Ultimately, energy can influence the behavior and properties of matter in various ways.
What do nuclear power plants have to do with nuclear energy?
Nuclear power plants use nuclear energy as their source of power. They harness the energy released from nuclear reactions (such as fission) to generate electricity. The heat produced by these reactions is used to create steam, which drives turbines to generate electricity.
Where energy is given off?
Energy is given off during exothermic reactions, where the system releases heat to the surroundings. Examples include combustion reactions, neutralization reactions, and some types of nuclear reactions.
Chemical reactions that create energy within a cell are referred to as?
6co2
What is the difference between catabolic and anabolic reactions in terms of their impact on cellular metabolism?
Catabolic reactions break down molecules to release energy, while anabolic reactions build molecules using energy. Catabolic reactions provide energy for cellular processes, while anabolic reactions require energy to create new molecules. Together, these reactions regulate cellular metabolism by balancing energy production and consumption.
What are the series of reactions that take inorganic molecules and light energy to create glucose?
The Calvin Cycle is the correct answer.
Which reactions requires or stores energy?
Endothermic reactions require energy while exothermic reactions release energy.
Do all reactions release energy?
No, not all reactions release energy. Some reactions require an input of energy to proceed, and these are called endothermic reactions. Endothermic reactions absorb heat from the surroundings rather than releasing it.
Chemical reactions that require energy?
endothermic reactions require energy
What kind of reactions release energy?
Exothermic reactions release energy.
In what processes are energy released?
condensation A+ : )
What reaction gives out energy?
If by energy you mean heat energy exothermic reactions.
How do the light reactions and dark reactions work together?
The light reactions provide energy carriers for the dark reactions.
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.
What chemical reaction produces the sun and energy?
These are not chemical reactions but thermonuclear reactions.
