Are the clues that indicate a chemical change always reliable?
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 chemiluminescence - formation of new compounds
Does gas always indicate a chemical change?
Not allways; a liquid can disappear during evaporation but this is a physical process.
What should not be used to indicate a chemical reaction?
Change of shape can not be used to indicate a chemical reaction has happened. Examples of evidence of a chemical reaction are changes in odor or color.
What change in a physical property of matter can indicate?
a physical change or a chemical change
Is color he least reliable indicator of a chemical change?
No, the least reliable indicator of a chemical change is shape. Change of shape usually indicates a physical change, unless the material change resulted from a recombination or decomposition of the material's chemical form, as in the rotting of vegetable matter.

Is milk sours a example of physical change?
No, a chemical change. Taste and smell are indicators of chemical composition, so a change in those would indicate a chemical change.
Can the development of a solid can indicate the occurrence of a chemical change?
Yes
