Solution used to white wash the walls is Quick lime(CaO) and when it is mixed with slaked lime [Ca(OH)2]. When this paste is used for white washing it combines with atmospheric CO2 to form calcium carbonate (CaCO3) which gives it a shiny texture.
Slaked lime or Ca(OH)2 is used for white washing the walls. But when Ca(OH)2 react with CO2, it gives Calcium Carbonate and water which gives a smooth finishing to the walls. ... When this paste is used for white washing it combines with atmospheric CO2 to form calcium carbonate (CaCO3) which gives it a shiny texture.
The method used for measuring the small distance is by using the scales and the distance measured over long distance is by inch tape or measuring tape.
Having the same electronegativity means that the both elements will form a nonpolar bond. The shared electrons of the bind will be found equidistant from the nucleus of the two atoms because none has an unusual ability to attract the electrons of a bond towards itself.
