Having negligible analytical powers, the small fish depends upon reaction for much of his choice of activity.

Sulfide minerals and analogous compounds produce gases upon reaction with oxygen.

CI is used as an iodination reagent, often upon reaction with base.

Some structures are intrinsically more sensitive to decomposition upon reaction with oxygen.

Some peroxide salts release oxygen upon reaction with carbon dioxide.

In this text, Parrado also touches upon public reaction to this event:

Acetaldehyde forms a stable acetal upon reaction with ethanol under conditions that favor dehydration.

Silver cyanides form structurally complex materials upon reaction with other anions.

Upon reaction with nitric acid, most metals give the corresponding nitrates.

Often, this substrate changes color upon reaction with the enzyme.
