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
A vacuum distillation is used when the boiling point of the compound or the solvent is too high in order to distill the compound or the solvent off without significant decomposition. is based on the fact that under vacuum the boiling point of the materials is lower than at normal atmospheric pressure.
