photosynthesis
nuclear chain reactionNote: there are also chemical chain reactions (e.g. polymerization), of course they involve no neutrons
a chemical reaction in which simple molecules are added to each other to form long chain molecules without by products
Fire is not invisible; fire is the chemical chain reaction from combustion that creates heat and light. Combustion, which is the actual burning process, is strictly chemical rearrangement and is invisible - but once you add oxygen to it, it becomes visible as fire.
The rusting metal of the chain is chemical and the towel that is now wet is physical. The water is still water but the metal is now been oxidized.
Mitochondria get rid of carbon dioxide and water as chemical waste products. Carbon dioxide is produced during the process of cellular respiration, while water is a byproduct of the electron transport chain in mitochondria.

Bio-accumulation.

Lighting a match starts a chain reaction which boosts the materials of the match tip, the wood with oxygen. These process changes the substance chemical formula, thus chemical change happens.

True, The Spending Chain Process consists of the Acquistion Process and the Accounts Payable process.
It would disrupt the entire food chain of the entire U.S. if we did not.
Value chain analysis is the process to determine which process of production is increasing the value of product and which is not so that the product manufacturing cost can be reduced by eliminating that process from the production chain.
With a properly maintained vehicle a timing chain (not a belt) will last a very long time. Up to 30 years.
The entire chain of command.
