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
This method is called âfractional distillationâ. The difference between the apparatus used for simple and the apparatus used for fractional. distillation is the presence of a âfractionating columnâ in the fractional distillation. In a distillation, liquid is converted to vapor by heating and the vapor is then condensed back to liquid by cooling.
