chemical decomposition
Let an agent explain chemical decomposition and its types, describe examples and applications including polymer degradation and recycling, relay safety considerations, and support chemistry learning.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain chemical decomposition and its types, describe examples and applications including polymer degradation and recycling, relay safety considerations, and support chemistry learning.
A chemical reaction in which a compound breaks down into simpler substances or elements, driven by heat as thermal decomposition, by electricity as electrolytic decomposition, by light or by chemical agents, including the depolymerisation and thermal degradation of polymers; decomposition reactions are the reverse of synthesis, are used in industry, recycling and analysis, and can be hazardous when they release gases or heat rapidly.
What it is for: Breaking compounds into simpler substances.
It can be explain types; describe examples and applications; relay safety considerations; support learning.
