Background The melting point of a compound is the temperature at which the solid is in equilibrium with its liquid. A solid compounds changes to a liquid when the molecules acquire enough energy to overcome the forces holding them together. A mixture melting point is useful in confirming and used to indentify an unknown compound‚ which we will be doing in this particular experiment. Purpose Measure the melting points of pure benzoic acid and pure mandelic acid. Determine the eutectic composition

(5). a) What are sheet-molding compounds (SMC)? Bulk-molding compounds (BMC)? Sheet-molding compound (SMC) is a fiber glass reinforced thermosetting compound in sheet form‚ usually rolled into coils interleaved with plastic film to prevent auto adhesion. Made by dispensing mixed resin‚ fillers‚ maturation agent‚ catalyst and mold release agent onto two moving sheets of polyethylene film. The lower one also contains chopped glass roving or glass mat.

EXPERIMENT 3 DETERMINATION OF ORGANIC MATTER BY WALKEY- BLACK WET OXIDATION METHOD OBJECTIVE: This method determines the percentage of organic carbon and organic matter in the soil. INTRODUCTION The soil sample is suspended in standard potassium dichromate (K2Cr2O7) solution to which concentrated sulphuric acid is then added. The heat generated on adding the sulphuric acid and the presence of chromic acid creates strong oxidizing conditions. The excess chromic
