Can someone explain the GCMS of this sample?
This was the procedure:
A solution of acetophenone, 20 mmoles, and
metha-chloroperbenzoic acid (mCPBA)
36mmoles, are stirred in 50mL of distilled water at 80°C for 4 h
and monitored by
TLC (eluent: ethyl acetate). The reaction mixture is cooled to
room temperature and
extracted with dichloromethane (3x30mL). The combined organic
layers are
washed with saturated NaHCO3, and NaCl brine solution. The
solution is then dried
with MgSO4 and the solvent...

Can somone show me how to do the 1st problem? Need to
find the LS and SS for the fit and the LH and SH for the hole.
Fits are all SHAFT BASIS METRIC but the shaft and hole diameters can not be used right out of the table. This is because the 3mm shaft tolerance does not match. You will need to lookup the "Fit" from the table, and then use the LS (Largest Shaft) and SS (Smallest Shaft)...

In C++ Programming: Using a single for loop, output the even numbers between 2 and 1004 (inclusive) that iterates (loops) exactly 502 times. The outputted numbers be aligned in a table with 10 numbers per row. Each column in the table should be 5 characters wide. Do not nest a loop inside of another loop. Hint: First create and test the code that output the numbers all on one line (the command line will automatically wrap the output to new...
