    Title: Nitration of Methyl Benzoate Objective: To prepare methyl-3-nitrobenzene from nitration of methyl benzoate. Results and calculations: Density = 1.094 g/ml = Mass of methyl benzoate = 1.094 g/ml x 2.8 ml = 3.0632 g no. of mol of methyl benzoate = = 0.022499 mol 1 mol of methyl benzoate produced 1 mol of methyl m-nitrobenzene. Therefore‚ 0.022499 mol of methyl benzoate produced 0.022499 mol of methl

    There are three main rock types present in Ireland: Igneous‚ sedimentary and metamorphic. Igneous rocks are rocks which have crystallized from molten rock. Sedimentary rocks are rocks which have formed due to the gradual accumulation of sediment. Metamorphic rocks are rocks which have once existed as igneous or sedimentary rocks but changed due to great heat or pressure. Over the course of my essay‚ I will account for five rocks found in Ireland and there probable rock forming conditions. Granite
