After the reaction is completed, we proceed to isolate (work- up) and purify at C (246.29 g/ mol) yielding 0.300 g of the pure product. Calculate the% return for C showing his work. please show every single step and calculationsA core sample is saturated with an oil (?o = 35oAPI), gas and water. The initial weight of the sample is 224.14 g. After the gas is displaced by water (?w = 1 g/cm3 ), the weight is increased to 225.90 g. The sample is the placed in a Soxhlet distillation apparatus, and 4.4 cm3 water is extracted. After drying the core sample, the weight is now 209.75 g.

The rubber ball calorimeter was initially calibrated using the reaction of 7.0 mL of 0.200 M HCl and 14.0 mL of 0.1000 M KOH. This measured a temperature rise from 15.7 °C to 27.9 °C. After that, the heat of reaction was calculated for a combination of 2.00 mL of 1.00 M NaOH and 5.0 mL of 1.00 M HX. This represented a temperature rise of 3.7 degrees Celsius. What is the calorimeter's heat capacity in J/°C? (Δ??????????????? =-55.85 kJ/mol)? For the reaction between NaOH and HX, create the chemical and net ionic equations that are equally balanced.
