A Black market is said to take place when there is illegal buying and selling of goods and services.

Black markets usually take place outside the government's rader and without government's knowledge so as to avoid tax or any other government regulations.

Black market presents the avenue for government prohibited goods like hard drugs, war weapons and firearms to be bought by criminals.

A black market can also occur on the web for cyber criminals or those who are involved in computer hacking. To achieve their malicious aim, these individuals will go into the dark web and purchase or rent their respective hacking tools for a fee. Normally, payments are made in crypto currencies.

However, a black market isn't generally considered as bad. Infact, it has its advantages and disadvantages.

Economics

Below are definitions of demand from the perspective of some notable professors:

The demand for goods is a schedule of the amounts that buyers would be willing to purchase at all possible prices at any one instant of a time.

Professor Mayers

Demand is the various quantities of goods that would be purchased per time period at different prices in a given market.

Professor Hibdon

The demand for anything, at a given price is the amount of it which will be bought per unit of time at the price.

Professor Benham

Generally, demand is defined as the willingness of a person, buyer or consumer to buy a specific quantity of goods or service at a given price and time.

From the above definitions, we can infer that the definition of demand is referenced to three major factors. These are:

  1. Quantity of Goods Demanded

In chemistry, hydrocarbons can be classified as either aliphatic or aromatic. Recently, both classifications of hydrocarbon were based on their structure rather than their origin.

Aliphatic hydrocarbons are put into three main groups according to the types of bonds they possess. These are:

  1. Alkanes

  2. Alkenes

  3. Alkynes

They are shown in the image below:

Alkanes, Alkenes and Alkynes - Len Academy

It's important to note the followings:

  • Alkanes have single bonds (only) in their structures.

  • Alkenes always have a carbon-carbon double bond present in their structure.

  • Alkynes always have a carbon-carbon triple bond present in their structure.

 

Aromatic hydrocarbons are classified into:

  • Arenes: They contain benzene ring as a structural unit. Below is the structure of a benzene ring.

Benzene Ring - Len Academy

 

  • Nonbenzenoid aromatic hydrocarbons: They possess special stability but lack a benzene ring as a structural unit.

Chemistry

Organic chemistry is the study of carbon and it's compounds.

Carbon is the focus of organic chemistry because it has a wide chemical diversity in the sense that it can combine with other carbon atoms to form a long chain of carbon molecule. This ability and process whereby carbon can form a long chain of itself is called catenation.

The organs of government (also referred to as arms of government or branches of government) are:

  1. Executive

  2. Legislature

  3. Judiciary

These three arms of government serves as a separation of power.

Separation of Power implies that they carry out their distinct (separate) functions and responsibilities in accordance to the nation's constitution.

The president (who is number one citizen of a country and the Commander-in-Chief of the Armed Forces) is the head of the executive arm of government. It is the responsibility of the executive to enforce or execute the law.

 

The legislature is a group of elected persons who are required to make law.

In Nigeria, the legislature consist of the bicameral national assembly which are:

  1. The upper house or chamber (Senate)

  2. The lower house or chamber (House of Representative)

 

The judiciary is an independent arm of government whose power is enforced in the courts.

Like the executive and legislature, they function under the guidance of the constitution.

Please read more on the organs of government here

Government

Below are some functions of the executive arm of government:

  1. They ensure the security of the citizens in a country.

  2. The executive cannot pass laws into the constitution. Instead, they can forward bills to the legislature (or parliament) which will deliberate upon it. (Think of 'bill' as a proposal to be made into law; which will be submitted to the parliament in the form of a draft act).

  3. It is the president's responsibility to provide quality healthcare system, education, good roads (transport system), power, labour and finance through his ministers. For instance, the minister of agriculture oversees the affairs of agriculture in a nation. The ministers may also be accountable to the national assembly with regards to how they go about their ministries.

  4. They bring about maintenance of law and order in a country through the National Security Agencies (NSA) like the police, army, navy and air force.

  5. They prepare and execute the nation’s budget.

  6. The president approves the law into the constitution.
