Question
Explain the following reaction with the balanced equation.
Ferric oxide is reacted with aluminium.
Advertisements
Solution
Ferric oxide reacts with aluminium to form iron and aluminium oxide. This reaction is known as the thermit reaction.
\[\ce{\underset{\text{Ferric oxide}}{Fe2O_{3(s)}} + \underset{\text{Aluminium}}{2Al_{(s)}} ->[Ignited] \underset{\text{Iron}}{2Fe_{(l)}} + \underset{\text{Aluminium oxide}}{Al2O_{3(s)}}+Heat}\]

Answer the questions on the following passage.
The minerals from which the metal can be separated economically are called ores. Ores contain many types of impurities such as soil, sand and rocky substances along with metal compounds. These impurities are called gangue.
Metals can be extracted from their ores by means of various methods of separation. The process of extraction of metal in a pure state from the ores is also a part of metallurgy.
Ores are taken out from the mines and the gangue is usually separated from the ore at the site itself by various methods. Then the ores are carried out to the place where metals are produced. Here metals are extracted in pure form. Then metals are further purified by different methods of purification. This entire process is called metallurgy. Most metals being reactive do not occur in nature in the free state but are found in combined state as their salts such as oxides, carbonates, sulphides, and nitrates. however, the most unreactive metals that are not affected by air, water and other natural factors like silver, gold, platinum, generally occur in a free state. The compounds of metals that occur in nature along with the impurities are called minerals.
