Some possibilities are:
- change of color
- change of odor
- change of temperature
- release of a gas
- change of the aspect
- formation of a precipitate
- change of the viscosity
- an explosion
etc.
1. Color change from silver to green.
2. Gas released (bubbles)
3. Solution became cloudy
yes it as it forms a new substance
It is a chemical reaction
A chemical change is a chemical reaction.
chemical change. 2KClO3 ----> 2KCl + 3O2
Milk turning sour is a chemical change.
The properties mix together with the mixture.
Macaroni is a mixture not a change.
you can observe chemical reactions from its smell, colour, shape, or the change in it's properties
A mixture that produces a chemical reaction, scientifically speaking, is a chemical change.
By definition, a mixture is two or more substances that are physically combined. In a chemical change, the substance interacts with another substance and undergoes a chemical change. So, no, a mixture is not a chemical change.
It depends ont eh chemical change, because in some changes not all the components of the mixture are used.
The formation of a new substance is the criterion for a chemical change. You can't have a chemical change without the formation of at least one new substance. As you can't observe a chemical property without setting a chemical change in motion, the answer to your question is yes.
Yes. If you observe a chemical property, the substance will be undergoing a chemical change, which by definition produces a new substance.
Yes. If you observe a chemical property, the substance will be undergoing a chemical change, which by definition produces a new substance.
Yes. If you observe a chemical property, the substance will be undergoing a chemical change, which by definition produces a new substance.
