What are the four clues to a chemical reaction?
heat is produced, light is produced, gas is produced, the chemicals change color.
What is one of the signs of a chemical change?
There are four common clues to the fact that a chemical change is occurring, though they are not always definitive:a gas is produceda precipitate is formedthere is a colour changethere is a large energy change.
Which is a clue that a chemical change has taken place?
Well, there are four clues to a chemical change. The first clue is a transfer of energy. For example, energy is transferred from methane in natural gas to cook food. The second clue is a change in color. Food browning while being cooked is an example of this. The third clue is the production of a gas. Some cleaning chemicals create bubbles upon contact with soap scum. This is evidence of a chemical change. The last clue is the formation of a precipitate. The ring of soap scum in a bathtub is a precipitate, and evidence of a chemical change.
What are the four clues of physical change?
I think you mean, solid, liquid, gas and plasma (very very hot gas)
What are 4 things that indicate a chemical change?
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

List four clues that a chemical reaction is occurring?
To tell if a chemical reaction has occurred look for these four things: 1) color change 2) the formation of gas bubbles 3) formation of a precipitate 4) temperature change
What is are four things that indicate that a chemical change probably happened?
Four things that indicate a chemical change probably happened include color change, formation of a precipitate, evolution of gas, and change in temperature. These signs suggest that a new substance with different chemical properties has been formed.
