I need to write this prediction sheet to identify an unknown
You will write up a prediction sheet that lists all of the unknowns and the possible tests you could use with the expected results. HINT: Always begin with solubility
Possible unknowns:
1. Pentane
2. Cyclohexene
3. 1-Pentanol
4. 2-Pentanol
5. 2-Methyl-2-Propanol
6. Pentanal
Reagents or Items:
Vegetable Oil
3M H2SO4
Bromine in Vinegar
5% K2Cr2O7
Acetone
ZnCl2 in concentrated HCl (Lucas reagent)
1% KMnO4
6M HCl
pH paper
Benedict's Reagent
Tollen's Test reagent (plus neutralizing reagents)

A100 kmol/h stream that is 97 mole% carbon tetrachloride (ccl4) and 3% carbon disulfide (cs2) is to be recovered from the bottom of a distillation column. the feed to the column is 16 mole% cs2 and 84% ccl4, and 2% of the ccl4 entering the column is contained in the overhead stream leaving the top of the column. calculate the mass and mole fractions of ccl4 in the overhead stream, and determine the molar flow rates of ccl4 and cs2 in the overhead and feed streams. 12. mw_ccla- 153.82; mw_cs2-76.14.

Asubstance is held in an open container. its particles move past one another at random speeds but do not leave the container. heat is removed from the system, and the particles slow down. when enough heat is removed, the particles no longer have enough speed to overcome the weak attractive forces between them. when this happens, the substance enters its solid state. the process described above is known as .
