What else can I help you with?
Are chemical changes irreversible If yes then what about the chemical reactions that are reversible Don't we say that all chemical reactions are chemical changes?
some chemical changes can be reversed but they are hard to reverse usually
What are some chemical changes caused by changes in temperature?
Freezing a popsicle
Chemical change good or bad?
Chemical changes can be both good and bad. Some chemical changes are necessary for life to exist, such as in the process of digestion. However, some chemical changes can be harmful, such as those that occur in pollution or the degradation of materials.
What are some examples of chemical changes found in animals?
Examples of chemical changes in animals include the digestion of food in the stomach, the conversion of nutrients into energy through cellular respiration, and the synthesis of hormones and enzymes. These chemical processes are vital for the survival and functioning of animals.
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 some cooking chemical changes?
because it mixes substances that makes a chemical change
Can a chemical change be undone?
Some chemical changes are reversible, others are not.
What are some physical and chemical changes in cooking?
hot cold
What are some chemical changes when cooking?
Some chemical changes when you are cooking are:burning the foodOVERcooking itUNDERcooking itsorry for only three examples. those are the ones that i can only think of so far.
Are chemical changes reversible?
I would argue that in theory all chemical changes are reversible. However it is certainly true that considerations of enthalpy and entropy mean that some are totally impractical to reverse.
What are some chemical reactions and changes that happen when cleaning pennies?
something
What are some useful chemical change?
Some useful chemical changes are when a solid changes into a liquid. Such as when ice melts it is turned into water.Sorry but I am afraid that is wrong.Freezing, melting and evaporation including sublimation, i.e., Changes of State, are all physical, not chemical, changes.As for "useful" chemical changes.... Almost all biological processes, the conversion of fuel to its oxides etc with consequent release of heat &/or light, the list goes on!
