What else can I help you with?
Why do reactions always involve a change in energy?
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.
Is pasteurization chemical or physical change?
Pasteurization involve chemical reactions.
What is the total of chemical and physical reactions?
Chemical reactions involve a change in chemical composition, while physical reactions involve a change in state or appearance without changing the chemical composition. Together, they encompass the various transformations that can occur in matter.
How is corrosion of copper a chemical change?
Corrosion involve chemical reactions - and these are chemical changes.
Is reactions a chemical or physical?
Reactions can be both chemical and physical. Chemical reactions involve breaking and forming chemical bonds leading to the formation of new substances. Physical reactions involve changes in state, shape, or form of a substance without changing its chemical composition.
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.
Chemical reactions always involve changes in a chemical?
There will always be changes in one of the reactants. In some chemical reactions, one of the chemicals works as a catalyst to encourage a reaction between two or more chemicals but does not change during the reaction.
Why cooking of rice is a chemical change?
Because cooking involve also chemical reactions.
How can you tell at baking a cake produces a physical change?
Baking is a chemical change because involve chemical reactions.
Why is reactivity not a phyical property?
A physical change doesn't involve chemical reactions, change of the molecule structure.The chemical reactivity is about the ability of an element or compound to realize chemical reactions.
Is steaks grilling a chemical or physical change?
This is a chemical process because involve chemical reactions.
