Burning coal is a chemical process in which coal reacts with oxygen and forming carbon doxide and or monoxide.
it is chemical property. they use the word decomposition immaterially shows changein chemical composition.hence chemical change.
Coal hasn't a chemical formula; the major and useful component of coal - carbon - has the chemical symbol C.
Natural gas, gasoline, fuel oil, coal, and LPG burning are all chemical reactions ( chemical changes ). The reactants ( fuel and oxygen ) react yielding primarily CO2 and H2O., which are different chemical species than the reactants.
Phisical re action: when the wax turns to liquid when the liquid cools down it turns to solid which goes back to its own form again soryy i don't know the chemical reaction
burning of coal is chemical change
a physical change
it is a physical toxicant

Burning coal is a chemical change. Anytime heat is released (as such in fire) it will be a chemical property change.
No, chemical I think .
Chemical. It is called combustion.
No. Burning anything is a chemical change.
No, it is a chemical change
chemical. A chemical change is a change where a substance is changed and a new substance is formed. in the case of coal when the solid carbon in the coal combines with the oxygen in the air carbon dioxide (CO2) is formed.
It is a chemical reaction. The coal (which is mostly carbon) reacts with oxygen to form carbon dioxide.
Burning coal is a chemical reaction, a chemical change; but the solid reactant is transformed in gaseous products (H2O and CO2) - this is a physical change.
