If youâre self-employed, youâre responsible for paying your own share of those Social Security and Medicare contributions, collectively known as SECA. But fear not! You too can be taxed just like your traditionally employed peers by claiming an SECA deduction on Line 27 of Form 1040. You will compute this amount as part of Schedule SE.
when the boiling point difference is less than 20 degrees; limited to larger samples in fractional distillation why are we using a GC in this experiment to determine the composition of the fractions I obtained from simple distillation
What is Distillation? Distillation is a widely used method for separating the component substances from a liquid mixture by selective evaporation and condensation. To separate a mixture of liquids, the liquid can be heated to force components, which have different boiling points, into the gas phase. In industrial chemistry, distillation is a unit operation of practically universal importance, but it is a physical separation process and not a chemical reaction.
