Explanation:
Stainless steel is an alloy of iron (Fe) and chromium (Cr). Chromium forms a film of its oxide, called the passive layer on the surface of metal thus preventing the oxidation of iron present in the alloy. This chromium oxide layer is present tightly stuck to the surface of the metal and is highly corrosion resistant. So, the presence of chromium provides resistance against corrosion of iron. Other metals like Ni, Mo, Cu and Al are also present in stainless steel. They provide additional features like toughness and formability.
Explanation:
Geometric isomers are molecules that are locked into their spatial positions with respect to one another due to a double bond or a ring structure. For example, consider the following two molecules.
