What else can I help you with?
Why do chemical reactions always involve a chemical change?
Chemical bonds always break in chemical reactions, causing changes in energy.
Why do chemical reactions always involve a change in energy?
Chemical reactions involve the breaking and formation of bonds between atoms, which requires energy. The energy change in a reaction is needed to overcome the activation energy barrier and initiate the process. This change in energy is essential for the rearrangement of atoms and the formation of new substances.
Do chemical reactions always involve changes in energy?
no
Do reactions create energy?
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.
Why do we say that chemical reactions always involve changes in energy?
Chemical reactions involve the breaking and forming of chemical bonds, which requires energy to overcome or release. This results in changes in the potential energy of the system. Additionally, the activation energy required to start a chemical reaction is a clear demonstration of energy change.
What are energy changers?
Chemical reactions usually involve change of heat due to energy absorbed or evolved during reaction.
Do reactions always involve a transfer of energy?
Yes, reactions typically involve a transfer of energy between molecules. This transfer can result in breaking or forming chemical bonds, leading to changes in the energy of the system. Whether energy is absorbed or released depends on the specific reaction and its thermodynamic properties.
Is energy involved in all changes?
yes all changes involve exchange in energy
Why is burning of gas considered a chemical change?
All burning reactions involve chemical reactions (chemical changes).
A chemical property is a change in what?
There are many different possible property changes in a chemical change. You must post the specific reaction for anyone to tell you exactly.
Why does a change in teperature indicate that a change reaction may have occured?
Chemical reactions that involve bond-breaking tend to absorb energy from the surroundings, making the surroundings cooler. Chemical reactions that involve making bonds release energy, which makes the surroundings hotter. An example of a temperature change in a chemical reaction is when a burning fire produces heat.
What change releases energy into its surroundings?
Exothermic reactions release energy into their surroundings. These reactions involve the release of heat, light, or sound, resulting in a temperature increase in the surrounding environment. Examples include combustion, oxidation reactions, and many types of chemical reactions.
