The stationary phase of the GC columns in the organic chemistry labs is silicone oil, and so the boiling points of the sample compounds determine the order of elution. The highest boiling species is the last to elute from the column. In the analysis of your distillation fractions by GC, the peak that elutes first from the column will correspond to which component of the mixture?

An observation that requires measurement is called quantitative observable or qualitative

Jose and eric were given four samples in lab. the results of their analysis are shown in the table. based on the data they collected, which sample is most likely a metal?

In a heat engine of 1000 j of heat enters the system and the piston does 500 j of work what is the final internal energy of the system if the inital energy was 2000 j we have to do all of these down here 1)write the equation 2)list out your know variables 3)plug the numbers into the equations 4)solve 5)write your solution statemtn that includes inital energuy and final energuy added
