Br2 adds across the double bond in cyclohexene. Cyclohexane and aromatic hydrocarbons (toluene) don't react in the4 cold and with no uv light.

KHP + NaOH ==> NaKP + H2O mols KHP = grams/molar mass From the equation, mols KHP = mols NaOH. M NaOH = moles NaOH/L NaOH

The VERY BEST way is to visit an airport, including flight operations, but I don't think that is allowed anymore.(What does that tell you about our world today?)_ Two other ways are, as Ms Sue has suggested is read, read, read. Another is to invite a towe...

I answered this elsewhere. The unit is the mole.
