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.
As per the series of reactivity:There will be a decrease in reactivity to Right from Left: Potassium -> Sodium -> Lithium -> Calcium ->Magnesium -> Aluminium -> Copper -> Zinc -> Ferrous -> Tin (Sn) -> Lead (Pb) -> Hydrogen -> Copper -> Mercury -> Silver -> Gold This shows that when a metal reacts with other metals, there will be a displacement reaction or displacement from their solution.
a)H2SO4 + Zn ---> ZnSO4 + H2
b) Two metals other than it are Al(aluminium) and Ca (calcium)
decomposition reaction are called as opposite of combination reaction because in combination reaction two or more substances combine to form a more product not in decomposition reaction a single substance breaks down into two or more simpler substances.
for e.g. combination reaction •••√√√√•
C + O2.> CO2
But in a decomposition reaction
H2O ELECTRICITY> H2 + O2.
Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound. Both metals and non-metals take part in displacement reactions. Example : Reaction of iron nails with copper sulphate solution.
During indigestion (caused due to the production of excess of hydrochloric acid in the stomach), we administer an antacid (generally milk of magnesia,Mg(OH)2, which is basic in nature). The antacid neutralizes the excess of acids and thus gives relief from indigestion
nuetralisation is a type of chemical equation

The word "neutralization" is used because the acid and base properties of H+ and OH- are destroyed or neutralized. In the reaction, H+ and OH- combine to form HOH or H2O or water molecules. A neutralization is a type of double replacement reaction.
When an element displaces another element from its compound known as displacement reaction.
Example = Fe(s) + CuSO4(aq)—› FeSO4(aq) + Cu(s).
