Example of market structures of monopoly

IgorC [24]

Answer: A monopoly is the absence of competition in the market.

Explanation:

In such circumstances, the market creates a monopoly of one producer who takes huge capital and dictates prices. An example of a monopoly on the market is the existence of only one company that makes up the entire economic branch. In such circumstances, the monopolist can increase the product's price without losing the entire sale, i.e., operating successfully. In that situation, the monopolist remains the only one on the market, and the competition has no access to the market.

5. Uranium has three common isotopes. If the abundance of 2U which has an atomic mass of 233.878 amu is 0.01%, the

Temka [501]

Uranium has three common isotopes. The average atomic mass of uranium is 23.7 u/atom.

<h3>What are isotopes?</h3>

Isotopes are similar elements that have a different number of protons.

Uranium has three isotopes

The abundance of 2U has an atomic mass of 233.878 is 0.01%

The abundance of U has a mass of 234.892 amu is 0.71%

The **U has an atomic mass of 237.911 amu is 99.28%

Let's assume we have 10 000 atoms of Uranium

Mass of the 0.01 atoms = 0.01 x 233.878 = 2.33878

Mass of the 0.71 atoms = 0.71 x 234.892 = 166.773

Mass of the 99.28 atoms = 99.28 x 237.911 = 23,619.80

2.33878 + 166.773 + 23,619.80 = 23,788.8

23,788.8 / 1000 = 23.7 u/atom

Thus, the average atomic mass of uranium is 23.7 u/atom.

A balanced chemical reaction equation is one in which the number of atoms of each of the atoms are the same on both sides of the reaction equation.

<h3>Balanced reaction equation</h3>

A balanced reaction equation is a type of reaction equation in which the number of atoms of each reactant on both sides of the reaction equation are the same.

Let us now try to balance each reaction;

2H2 + O2 ----> 2H2O
S8 + 12O2 -------> 8SO3
2HgO ----> 2Hg + O2
Zn + 2HCl ------> ZnCl2 + H2

Hence a balanced chemical reaction equation is one in which the number of atoms of each of the atoms are the same on both sides of the reaction equation.
