2. Sulphides are the oldest ores, formed in the Earth's history when there was a lot of sulphur from volcanic activity. 3. Oxides formed later when photosynthesis in plants released large amounts of oxygen into the atmosphere. 4. Iron ore is the most common element in the world and makes up close to 5% of the Earth's crust.
This is derived by taking the compound valency. In general, Oxygen (O) holds a valency of 2, and Iron (Fe) holds a valency of 3. When we write the chemical formula, it is a common process where the compounds usually exchange valencies to attain a balanced and neutral state. Thus, the valency of Oxygen goes to Iron and vice versa.
Write the name and formula of the ores of iron. Answer: Question 33. Define periodicity. Answer: The electronic configurations of elements help us to explain the periodic recurrence of physical and chemical properties. Anything which repeats itself after a regular interval is called periodic and this behaviour is called periodicity. Question 34.

3. What is mineral ore used for? Ans: Ore is a deposit of one or more precious minerals in the Earth's crust. The most important ore deposits, such as copper, silver, and iron, contain metals that are essential to industry and trade. Copper ore is mined for a wide range of industrial applications.
Ores containing very high quantities of hematite or magnetite (greater than ~60% iron) are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. main ore is magnetite (Fe 3O4, 72 ...
