What else can I help you with?
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 are the chemical and physical changes of photosynthesis?
There are no physical changes. there are only chemical changes.
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.
Changes in properties of matter are called?
physical or chemical changes
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 is the process in which substances undergo chemical changes called?
chemical changes
What can chemical changes change?
Cooking food can cause chemical Changes
is The clues that indicate a chemical change are always reliable?
The clues that indicate a chemical change, such as color change, gas production, temperature change, and the formation of a precipitate, are generally reliable indicators. However, they are not infallible, as some physical changes can produce similar signs. Therefore, while these clues can strongly suggest a chemical change, confirming the change often requires further analysis or testing.
Are all physical changes accompanied by chemical changes?
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
Is iron physical changes or chemical changes?
Iron is a chemical element, not a change.
Chemical changes can be reserved by physical change?
No, chemical changes cannot be reversed by physical changes. Chemical changes involve the formation of new substances with different properties, while physical changes only affect the state or appearance of a substance without changing its chemical composition. Once a chemical change occurs, it cannot be undone by a physical change.
