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
Distillation is the process of separating two or more liquids based on differences in their boiling points. When the liquidsâ boiling points are very similar, however, separation by normal distillation becomes ineffective or impossible. Fractional distillation is a modified distillation process that allows the separation of liquids with similar boiling points. Boiling Points A liquidâs boiling point is the temperature at which it transforms to vapor.
