Hint :A plasticizer (UK: plasticiser) is a compound that is applied to a material to make it softer and more flexible, increase its plasticity, reduce viscosity, or reduce friction during manufacturing.
Question: Phthalates used as plasticizers in rubber and plastic products are believed to act as hormone mimics in humans. The value of Delta Hcomb for dimethylphthalate (C10H10O4) is –4685 kJ/mol. Assume 1.20 g of dimethylphthalate is combusted in a calorimeter whose heat capacity (Ccalorimeter) is 7.50 kJ/deg C at 22.0 deg C.
