acually the answer depends on the nature of chemical reaction under consideration and depending on the reaction, there are two possible answers: a change of state and absorption of energy.
Evidence of a chemical reaction include the following: formation of a precipitate formation of a gas change in temperature change in color
Some indicators of a chemical reaction are:- formation of new compounds - change of color- change of odor- release of a gas- change of the temperature (absorption or release)- change of the viscosity- formation of a precipitate- change of general appearance- possible explosion - sometimes a sound is produced - possible chemiluminescence
Chemical change. The formation of a precipitate is one indication that a chemical reaction has taken place.
Characteristics of a chemical change can include a temperature change, a color change, the production of bubbles, the production of a precipitate, and a smell.
The formation of a precipitate is a chemical change.
realease or absorption of energy product of a gas formation of a precipitate change in color
Formation of a precipitate; change in color; change in temperature; formation of a gas; emission of light.
Formation of a precipitate is evidence of a chemical reaction.
Formation of a precipitate is evidence of a chemical reaction.
The thickening is caused by the formation of a precipitate. The formation of a precipitate is a chemical reaction.

change in color, formation of gas and precipitate ;))
Evidence of a chemical reaction include the following: formation of a precipitate formation of a gas change in temperature change in color
Some observations: - change of colour - formation of a precipitate - change of odor - change of temperature - release of a gas - change of pH - change of viscosity etc.
The signs of a chemical reaction include change in temperature, change in color, formation of gas, formation of a precipitate, disappearance of a solid, formation of a new odor.
