Some indicators of a chemical reaction are:
- change of color
- change of odor
- release of a gas
- change of the temperature
- change of the viscosity
- formation of a precipitate
- change of general appearance
- possible explosion
- possible chemiluminiscence
What else can I help you with?
Can new compounds form during a physical change?
no because in a physical change it does not change the chemical make up, however, it does during a chemical change
Do chemical changes affect the chemical structure of a substance?
Yes, chemical changes result in a change in the chemical structure of a substance. During a chemical change, new substances with different chemical compositions are formed through the rearrangement of atoms and bonds. This is in contrast to physical changes, where the chemical structure remains the same even though the physical properties may change.
Is seeds to pumpkin physical or chemical change?
This process involve chemical reactions but also physical changes.
Is chemical change a temporary change Explain?
No, a chemical change is not a temporary change; it is usually permanent. During a chemical change, the substances involved undergo a transformation that alters their molecular structure, resulting in new substances with different properties. Unlike physical changes, which can often be reversed, chemical changes typically cannot be undone without undergoing another chemical reaction.
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.
Which property of matter changes during a chemical change but does not changes during a physical change?
The composition of matter changes during a chemical change as new substances are formed with different chemical properties. In contrast, the composition of matter remains the same during a physical change, with only the physical state or appearance of the substance being altered.
Is chemical energy related to chemical change?
Yes it is released/ absorbed during chemical changes.
Can new compounds form during a physical change?
no because in a physical change it does not change the chemical make up, however, it does during a chemical change
What are the differences betwen physical and chemical changes in terms of what happenes to molecules?
During a chemical change the molecule is transformed; during a physical change the molecule is not transformed.
Do chemical changes affect the chemical structure of a substance?
Yes, chemical changes result in a change in the chemical structure of a substance. During a chemical change, new substances with different chemical compositions are formed through the rearrangement of atoms and bonds. This is in contrast to physical changes, where the chemical structure remains the same even though the physical properties may change.
Is seeds to pumpkin physical or chemical change?
This process involve chemical reactions but also physical changes.
Is firing pottery a chemical change?
Yes. Chemical changes occur during the calcination of ceramics for pottery.
What is the chemical change in evaporation?
There isn't one. Evaporation is a physical change.
Can a substance produced during a physical change easily change back?
Yes. Chemical changes are irreversible, but physical changes can easily be changed back
Is Brewing beer a physical or chemical change?
Brewing beer involves both physical and chemical changes. Physical changes include crushing grains and boiling water, while chemical changes occur during fermentation when yeast converts sugars to alcohol and carbon dioxide.
When a substance changes into a diffrent substance what change has occurred?
chemical change
Is chemical change a temporary change Explain?
No, a chemical change is not a temporary change; it is usually permanent. During a chemical change, the substances involved undergo a transformation that alters their molecular structure, resulting in new substances with different properties. Unlike physical changes, which can often be reversed, chemical changes typically cannot be undone without undergoing another chemical reaction.
