Combustion clearly is a chemical change. In the combustion of a hydrocarbon, for example, you begin with the hydrocarbon and after combustion you end up with carbon dioxide (CO2) and water (H2O). This demonstrates that a chemical change has taken place.
Its the change of one substance into another substance.
Silver is a chemcial. More specifically, it is an element.
Combustion (burning) is a chemical change.
C3H8O3
HgO
CO
it produces glucose and oxygen
Formula: Ba3P2
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
You can change the air-to-fuel ratio to get less optimal combustion.
Yes, it is.
