Petrochemical refining for oil, petrol / gasoline
Manufacture of plastics
Production of ammonia by the Haber process for use as fertilizer, other feedstocks for other chemicals
The Question is somewhat obscure, (auto industry). little or no protection against rust to, submerging complete auto shell in a chemical rust inhibitor, in wood working, (glue) hide glues has been used for thousands of years, then came the advent of synthetic glues, PVA's and other resin glues. As a woodworker, I use many different types, general woodworking I use Titebond III, others (epoxy-hide-plastic resin,etc.). the type of glue is determind by what you are making. All brought fourth buy the R&D of chemicals.

non example of chemical change: one non example is ice. ice is NOT an example of chemical change.
A chemical change is a change that imply the change of the nature of molecules. Examples: neutralization of an acidic solution, thermal decomposition and generally all chemical reactions.
a precipitate.
Examples of chemical changes of matter include, but are not limited to: color change, formation of a precipitate, formation of a gas, change in energy.
Applying makeup is a physical change.

Physical change - make it frozen ; Chemical change - make it spoiled

Synthesis, decomposition, combustion, and oxidation are some examples of chemical changes (reactions) of matter.
Applying makeup is a physical change.
Its a chemical change. Chemical changes produces a new substance while physical change does not Examples of physical change are ripping paper, breaking a bottle and melting ice. Examples of Chemical change are cooking macaroni, rusting iron and mixing acids and bases to make salt and water
