The Hydrocarbon Benzence, C_6_H_6 boils at 80.1 Celcius. How much energy is required to heat 1.00Kg of this liquid from 20.0 Celcius to the boiling point and then change the liquid completely to a vapor at that temperature?
The specific heat capacity of liquid C_6_H_6 is 1.74 J g^-1 Celcius^-1, and the enthalpy of vaporization is 395 J/g. Report your result in joules.
In the purification of a mixture, what determines whether you use extraction or recrystallization as the initial procedure
If the theoretical yield for a reaction was 156 grams and I actually made 122 grams of the product, what is my percent yield
calculate the molarity of phosphoric acid in a solution that is 84% by mass phosphoric acid and has a dentisty of 1.87 g/m.
Description of amino acids, Chiral compounds occur when a carbon atom has four different things bonded to it. All but the simplest amino acids (glycine) are chiral because the alpha carbon has an amine group
