a precipitate is a solid that forms during a chemical reactions
The reactants become products; the molecules are changed.
Rusting is a reduction/oxidation reaction.
This type of reaction is oxidation.
chemical change or chemical reaction.
The word for these reactions is synthesis.
Chemical change and exothermic change
What is the chemical reaction of a dispoiable lighter
Rusting is a reduction/oxidation reaction.
This type of reaction is oxidation.
Chemical reaction
This is an endothermic reaction.
no chemical reaction takes place . when electrons are shared it is known as covalent bond
Anything being "toasted" is a chemical change. The browning that occurs is due to a type of chemical reaction called the "Maillard reaction." It's a reaction between amino acids (in proteins) and carbohydrates (sugars and starch) that give cooked foods their characteristic flavor.Another reaction that sometimes occurs when cooking foods is caramelization, which is similar in appearance but is a completely different reaction ... it's the pyrolysis of certain sugars.
chemical change or chemical reaction.
Chemical Change
no- melting is not a chemical change. It is merely a change in state of the same substance not a chemical reaction.
Rusting
