Short Chemistry Quiz On Iron Ore! Trivia
Welcome to a Short Chemistry Quiz on Iron Ore! Iron is one of the most interesting elements on earth, and being said, there is much that it can be used for in different fields. The quiz below is designed to help you review just how much you know about iron. Do give it a chance, and you might get to learn some new things in the process.
- 1.
What two substances must be present for rusting to occur?
- A.
Carbon and Hydrogen
- B.
Water and Oxygen
- C.
Water and Hydrogen
- D.
Gas and Water
- E.
Iron and Oxygen
Correct Answer
B. Water and OxygenExplanation
Rusting is a chemical reaction that occurs when iron reacts with oxygen in the presence of water. Water provides the necessary medium for the reaction to take place, while oxygen is the reactant that combines with iron to form iron oxide, which is commonly known as rust. Therefore, water and oxygen must be present for rusting to occur.Rate this question:

This is NOT a method of preventing the rusting of an object.
- A.
Coating the object with wax, paint or oil
- B.
Covering the object in Hydrochloric Acid
- C.
Coating the object in anhydrous calcium chloride
- D.
Using alloys
- E.
Covering the object in a more reactive metal

______________ and ______________ are the most abundant metals in the world.
- A.
Gold and Silver
- B.
Copper and Zinc
- C.
Aluminum and Calcium
- D.
Magnesium and Sodium
- E.
Iron and Aluminum
Correct Answer
E. Iron and AluminumExplanation
Iron and aluminum are the most abundant metals in the world. This is because they are widely distributed in the Earth's crust and have been extensively mined and used by humans for thousands of years. Iron is commonly found in the form of iron ore, while aluminum is primarily obtained from bauxite ore. Both metals have a variety of industrial applications and are essential for the production of numerous products, making them highly sought after and abundant in the world.Rate this question:

What is (an) iron ore?
- A.
The machine used to make mine iron from the ground
- B.
The primary reducing agent of iron
- C.
The chemical process used during the extraction of iron
- D.
The mineral from which iron is extracted
- E.
The gas produced when iron is burnt
Correct Answer
D. The mineral from which iron is extractedExplanation
Iron ore is the mineral from which iron is extracted. Iron ore is a natural resource that contains iron in various forms, such as hematite, magnetite, and taconite. It is mined from the ground and then processed to extract the iron, which is used in various industries for the production of steel and other iron-based products. Iron ore is an essential raw material for the iron and steel industry.Rate this question:

What is a blast furnace?
- A.
A structure used to extract iron from its ore
- B.
A machine used to burn iron in order to turn it into aluminum
- C.
The sound made when iron is combusted
- D.
A lethal chemical compound
- E.
The agent used to decompose iron
Correct Answer
A. A structure used to extract iron from its oreExplanation
A blast furnace is a structure used to extract iron from its ore. It is a large, cylindrical furnace made of steel and lined with heat-resistant materials. Inside the furnace, iron ore, coke, and limestone are heated to high temperatures. The coke provides the heat and chemical reaction necessary for the extraction of iron from the ore. The limestone helps remove impurities from the iron ore. As a result, molten iron is produced and collected at the bottom of the furnace. This process is crucial in the production of iron and steel.Rate this question:
