characteristics that can only be determined by a chemical reaction and a chemical change in the substance
a change in the form or physical properties of a substance, without a chemical reaction or the creation of a new substance
a change in the chemical composition or makeup of a substance
A chemical reaction in which a substance combines with oxygen, to produce an oxide
redox; a chemical reaction in which the oxidizing agent is reduced (by losing oxygen) and the reducing agent is oxidized (by gaining oxygen)
