Plastic materials (synthetic polymers) may contain: C, H, O, N, S, Si.
There are lots of different types of plastics, the ones normally encounterd contain a polymer and additives so they are not pure substances and you cannot write a balanced chemical equation for combustion.

A white precipitate of silver chloride forms on the plastic strip due to a chemical reaction between the chloride ions present in the plastic and the silver ions in the silver nitrate solution. The silver chloride can be removed from the plastic by rinsing it with water to reveal a visible change on the strip.

You've got another "chemical change here." One more and you've got a grand slam!
Plastic materials (with some exceptions) are chemical substances.
That depends on the chemicals present before the chemical reaction and sometimes the conditions under which the chemical reaction occurred.
No, making plastic containers is a chemical change as it involves the conversion of raw materials (such as polymers) into a new substance (plastic containers) through a chemical reaction. Physical changes only alter the appearance or physical state of a substance without changing its chemical composition.
The chemical formula is representative for the chemical composition of a compound.
Toothbrushes are typically made from plastic with nylon bristles. The handle is commonly made from a type of plastic like polypropylene, while the bristles are typically made from nylon. Additional components such as rubber grips or metal parts may also be present in some toothbrush designs.
