Is frying a chicken physical or chemical change?
Physical changes can be undone. It is not possible to unfry a chicken. The heat casues chemical changes in the meat and in any coating.
19. Which is nota possible clue that a chemical change has occurred The substance melts. The color changes. A precipitate forms. Bubbles are produced.?
The statement "The substance melts" is not a possible clue that a chemical change has occurred. Melting is a physical change, as it involves a change in the state of matter from solid to liquid without altering the substance's chemical composition. In contrast, color changes, precipitate formation, and bubble production typically indicate chemical changes.
Where is it possible to learn about chemical dependency?
One can learn about chemical dependency online through a number of websites. Wikipedia have information about substance dependence while one can find information on 'DRA Online' and 'John Muir Health'.
Are the changes in the state of matter chemical changes?
No, changes in state of matter (such as melting, freezing, boiling) are physical changes, not chemical changes. Chemical changes involve the formation of new substances with different chemical properties.
What changes can't be reversed by physical means?
Changes that involve irreversible chemical reactions, such as burning wood to ashes or baking a cake, cannot be reversed by physical means. Once the chemical bonds are broken or rearranged, it is not possible to return the substances to their original state through physical processes alone.
Are chemical reactions accompanied by chemical changes in energy?
Yes. Refer to endothermic and exothermic reactions to learn more.
Is frying a chicken physical or chemical change?
Physical changes can be undone. It is not possible to unfry a chicken. The heat casues chemical changes in the meat and in any coating.
Is hardness a change in chemical property?
There are many different possible property changes in a chemical change. You must post the specific reaction for anyone to tell you exactly.

Is energy change only involved with chemical change?
Energy changes are possible also in other situations.
What does Hess's law make it possible for you to do?
Hess's law makes it possible to determine the overall enthalpy change for a chemical reaction by combining the enthalpy changes of multiple indirect reactions that add up to the desired reaction. This allows the prediction and calculation of the energy changes in chemical reactions, even if direct measurement of the reaction is not possible.

What are the chemical and physical changes of photosynthesis?
There are no physical changes. there are only chemical changes.
What changes can't be reversed by physical means?
Changes that involve irreversible chemical reactions, such as burning wood to ashes or baking a cake, cannot be reversed by physical means. Once the chemical bonds are broken or rearranged, it is not possible to return the substances to their original state through physical processes alone.
do oreos undertake any chemical changes?
Do Oreos undertake any chemical changes? Yes. How can Oreo be a chemical changes? Cooking involve chemical reactions, modifications of chemical molecules.
Differences between physical changes and chemical changes?
Physical changes are changes that affect the form of a chemical substance, such as changes in state or shape, without changing its chemical composition. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are often irreversible.
