Explanation:
Removing the fuel will stop the fire, this is called a firebreak. Therefore, the fuel part of the fire triangle does firebreak.
The fire triangle can be described as a simple model for understanding the necessary ingredients for most fires. The triangle represents the three elements a fire requires to ignite: heat, fuel, and an oxidizing agent.
A fire naturally takes place when the elements are present and combined in the right mixture. A fire can be stopped or extinguished by removing any one of the elements in the fire triangle.
For example, covering the fire with a blanket blocks the supply of oxygen and can stop a fire. In large fires, decreasing the amount of oxygen is not an option because there is no effective way to make that happen in an extended area.
Fires in forests can be stopped by cutting down trees to make a gap known as a 'fire break'. Because cutting the trees can act as removing fuel.

Answer:
Liquefied petroleum gas
Answer:
Liquefied petroleum gas or liquid petroleum gas(LPG or LP gas),
B)Ar
C)Cl
D)Si
A is obiviously the answer here.
The three similarities are hydrogen is produces, metal floats and move around the water, and metal disappeared. The difference is potassium is more reactive than lithium.
When metal reacts with water, hydrogen and metal hydroxide is produced.
Potassium is more reactive than lithium.
Alkali metals are also reactive with water.
The metal self ignites.
Thus, the three similarities are hydrogen is produces, metal floats and move around the water, and metal disappeared. The difference is potassium is more reactive than lithium.

B) C + O = CO2
C) C+ O -> CO2
D) C, O, CO2
The correct option is C.
When writing chemical equations, the chemical symbols of the element are usually used together with numbers to indicate the ratio of each element in the chemical compounds. The additional sign is usually used in between the reactants and the products. The arrow sign in used to show the direction in which the reaction is proceeding. In the correct option given above, the arrow sign is used to indicate that the reaction is moving in the forward direction.
Answer:
C) C+ O -> CO2
