Question

Special strike-anywhere matches can light a fire by rubbing against any rough surface. They do not require a matchbox strip for rubbing the match heads contain an oxidising agent, such as potassium chlorate and a sulphide of:
A) Carbon
B) Phosphorous
C) Iron
D) Cobalt

Answer 1

As we know that fire is one of the major things in life. Fire is one of the four elements of the matter. Fire is one of the five elements of the world. Fire triangle is important for the concept of life. Fire basically required three things. That is air, fuel and heat. These three things are popularly called the Fire triangle. Fire is required for the oxygen. Presence of oxygen only Fire will happen. Absence of oxygen only Fire will not happen.

Complete answer:
Special strike-anywhere matches can light a fire by rubbing against any rough surface. They do not require a matchbox strip for rubbing the match heads containing an oxidising agent, such as potassium chlorate and a sulphide of Phosphorous.
Phosphorus sulphide is used to ignite the wood stick. After the ignition, Phosphorus sulphide burns vigorously due to the decomposition of potassium chlorate releasing the oxygen molecules. This oxygen molecule is the main reason for catching the fire. That is the reason Phosphorus sulphide is used for the match heads.
According to the above discussion we conclude, Special strike-anywhere matches can light a fire by rubbing against any rough surface. They do not require a matchbox strip for rubbing the match heads containing an oxidising agent, such as potassium chlorate and a sulphide of Phosphorous.

Hence, option B is correct.

Note:
In chemistry, the periodic table plays a vital role. In the periodic table there are totally $118$ elements. In the periodic table there are totally $18$ columns and $7$ rows. The columns are called groups. Hence, $18$ groups in the periodic table. The rows are called periods. Hence, totally $7$ period in the table. Oxygen is one of the elements in the periodic table. The symbol of Phosphorus is ${\text{P}}$. Phosphorus is one of the fifteenth group elements in the periodic table. The atomic number of Phosphorus is $15$. The mass number of Phosphorus is $30.9$. The atomic number of the element is nothing but the number of electrons or number of protons. The mass number of the atom is nothing but the sum of the number of protons and number of neutrons.
