Question

Which substance is important in making plastics?

zinc hydroxide
ammonia
acetic acid
nitric acid

Answer 1

None of the substances you've listed are typically used as primary raw materials in the production of plastics. However, the most relevant compounds that play a role in the production of plastics are usually polymers derived from petroleum products, such as polyethylene, polypropylene, and polystyrene, which are not mentioned in your options.

If you are looking for a substance that is often associated with the chemical industry or industrial processes, ammonia can be used in the production of certain types of plastics, particularly in the synthesis of polyurethanes. However, it is not a primary substance in the manufacturing of common plastics.

For general knowledge, the main substances used to create plastics include monomers like ethylene, propylene, and styrene, which are polymerized to form plastics.
