Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".

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.
