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.
Answer:
6 atm
Explanation:
Using the formula P1V1=P2V2
P1= Initial Pressure
V1= Initial Volume
P2= Final Pressure
V2= Final Volume
And knowing that at stp gas will always be at 1 atm
250L(P2) = 1500
P2= 6 atm
The theoretical mass of is 110.
<u>Explanation:</u>
Mass of one atom of calcium = 40 .
Mass of one atom of chlorine=35.5 .
Hence , two atoms would be
Therefore, mass of calcium chloride would be net sum both constituent atoms
=
So the theoretical mass of is 110.
The theoretical mass is the measure of item coming about because of an ideal chemical reaction, and in this manner not equivalent to the sum you'll really get from a response in the lab. It is the measure of item coming about because of an ideal chemical reaction, and therefore not equivalent to the sum you'll really get from a response in the lab.
