the chemical change i see is when the candle melts to a lower level
The candle is a mixture,containing many ingredients , he main component is three:C, H, O , the general chemical formula is written as C22H46, the reaction are CO2 + H2O.
the burning of a wax candle is quite a slow change, i can take hours until a candle burns out. When you compare this to some chemical reactions that take a few seconds to go to completion then this is a relatively slow change
A chemical change is when an obect change to a different kind of matter.
Spoiled food of any kind represents a CHEMICAL change.
The two types are chemical and physical changes.
A chemical change is one that creates compounds (products) that are different from the reactants. A physical change only alters the form or phase of the existing substances, not their chemical properties.
