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
There are two factors that determine a liquids boiling point: temperature and pressure. For water to be boiled at 20oC (room temperature - more or less), it would hâ¦ave to be subjected to about 2.339 kilopascals. See link below for more conversions.
