GREEN MUSSEL (Perna Viridis) SHELLS AS AN ADDITIVE COMPONENT IN HOLLOW BLOCK MAKING Abstract Hollow blocks have an important place in modern building industry. They are cost effective and better alternative to burnt clay bricks by virtue of their good durability‚ fire resistance‚ partial resistance to sound‚ thermal insulation‚ small dead load and high speed of construction. Hollow blocks being usually larger in size than the normal clay building bricks and less mortar is required‚ faster

Nitration of Naphthalene Wed 2/25/2015 Lab report # 1 Abstract: The purpose of this experiment was to nitrate naphthalene with nitronium ion‚ which is formed at low concentration from a reaction of nitric acid and sulfuric acid. The percent yield from the experiment was 54.4% of the product‚ and the melting point of the possible results were 59 °C for 1-nitronaphthalene‚ and 78°C for 2-nitronaphthalene. Introduction: Polynuclear aromatic hydrocarbons such as naphthalene can be nitrated
