Suppose you performed a distillation of a solution containing 1-pentanol (C5H12O), 2-pentanol (C5H12O), 3-pentanol (C5H12O), and methyl alcohol (CH4O). All three pentanols here have the same chemical formula, but they do have a different arrangement of their atoms (i.e. they are shaped differently), so this makes them have slightly different properties from one another. During the distillation, you collect the FIRST product that comes out, and set it aside. Then, you collect the SECOND product that comes out, and set it aside Then, you collect the THIRD product, analyze it, and determine that it has a formula mass of approximately 88 amu. What is the identity of this second product that you collected
There are approximately 2.60x10^13 red blood cells with atotal of 2.90g of iron. On the average, how many iron atoms are present in each red blood cell. (molar mass (Fe)= 55.85g

Potassium (atomic mass = 30.19 amu) has three isotopes with masses 38.9367 amu, 39.9640 amu, and 40.9618 amu. The abundance of the last isotope is 6.73%. Estimate the abundances of the other two isotopes
What undesired by-product could form if reactions involving benzyne are not done under anhydous conditions
A 2 mL sample was taken of a solution of barium iodate at 10 degree C. the sample was mixed with 2 mL of 0.5 M KI and 2 mL of 1M HCl. The transmittance of the mixture was read and compared to a calibration curve which indicated a concentration of ..
in carrying out an analysis of a mixture what do you expect to see when the tlc plate had been allowed to remain in the
a.) because Qc= 1, the system is at equalibrium. b.) Because Qc=1, more products will be formed. c.) Because Qc=1, more reactants will be formed. d.)Because Qc Kc,more reactants will be formed
Glucose is much more soluble in water than 1-hexanol even though both have 6 carbons. Explain
