Hematite, Fe₂O3, is an important ore of iron. (An ore is a natural substance from which the metal can be profitably obtained.) The free metal is obtained by
reacting hematite with carbon monoxide, CO, in a blast furnace. Carbon monoxide is formed in the furnace by partial combustion of carbon. The reaction is
Fe₂O3(s) + 3CO(g) → 2Fe(s) + 3CO₂(g)
How many grams of iron can be produced from 1.34 kg Fe₂03?
g Fe
Solid boron can be extracted from solid boron oxide by reac-
tion with magnesium metal at a high temperature. A second prod-
uct is solid magnesium oxide. (a) Write a balanced equation for the
reaction. (b) What mass of boron can be produced when 125 kg of
boron oxide is heated with 125 kg of magnesium?
(A) if both sentences are true,(B) if both sentences are false,(C) if the first sentence is true but the second is false, and(D) if the first sentence is false but the second is true.
1. In a redox reaction, the oxidation number of iron changed from +2 to +3; thus, sulfur is a reducing agent.
In a redox reaction, the oxidation number of nitrogen was unchanged; thus, nitrogen is an oxidant.
2. In a redox reaction, the reducing agent is oxidized and it gains electrons.
In a redox reaction, the oxidizing agent is reduced and it gains electrons.
3. Bending stress is also known as flexural stress.
The test used in observing the mechanical strength of chocolate is the three-point bend test.
4. The flexural strength of materials may be expressed in Pascals.
Magnesium is more reactive than silver; therefore, magnesium corrodes faster than silver with the aid of air, oxygen, and sea water.
