Answer:
- plastic (PVC, bakelite, polyethylene)
Explanation:
<em>Chemical reactions</em> involve the transformation of substances, called reactants, by breaking some bonds and forming new bonds, to obtain different substances called the products.
In the chemical reactions the atoms of the reactants are rearranged giving rise to the <em>products</em>, which will contain the same atoms but bonded differently or even as separate elements.
Using <em>chemical reactions</em> the human being can, for example, <em>produce</em> chlorine from sodium chloride solutions (from the oceans). In the same reaction, caustic soda (sodium hydroxide, NaOH) and hydrogen gas (H₂), are produced as by-products.
The properties of the products of a chemical reaction are very different from those of the reactants: sodium chloride is consumed by the humans every day in almost every meal, while chlorine and caustic soda are lethal if human beings consume them in some way.
Some examples of the variety of products produced from chemical reactions include:
- plastic (PVC, bakelite, polyethylene)
The list could be huge, because most of the things that the human being use are manufactured using chemical reactions.
