How do you know when there is No Reaction in a chemical reaction?
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
Signs of chemical change?
Some signs are: change of the color, change in odor, release of a gas, change of the temperature, formation of a precipitate, pH modification, viscosity variation, etc.
When a kettle is boiled you can tell it is not chemical change?
There are 4 evidences of a chemical reaction : -Change of colour. -Formation of precipitate. -Release of energy. -Effervescence.
What is called formation of is an indication of a chemical change?
You think to the formation of a new compound with a different smell, color, appearance, possible the release of a gas, a precipitate, etc.
What are the three visible signs of chemical reactions?
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
What is an example of the formation of a precipitate?
Formation of a precipitate is evidence of a chemical reaction.

What are the six types of evidence for a chemical change?
Types of evidence for chemical change include: A gas is evolved. A precipitate appears or disappears. Heat may be evolved or absorbed. A color change occurs. A substance disappears.
