Given the procedures described for using Pateur pipets from part A of experiment 0 as well as literature densities if needed, define how you would
a. Add about 0.8 ml of chloroform to a vial
b. Add about 1.2 grams of methanol to a vial
c. Decide the volume and mass of 38 drops of methylene chloride (CH2CL2)
The solubility of CO2 in water at 25C at 1 atm is 0.034mol/L. What is the mass of CO2 found in a 355 ml can of soda at 25 C, assuming the manufacturer used a pressure of 2.O atm of CO2 to carbonate the beverage.
Why do acid- and base-catalyzed elimination reactions often result in a mixture of products? Be specific. Hint - there is more than one reason.
Calculate the heat capacity of satan, i. e. Ni . if 30.0g of nickel at 100.0 c raises the temperature of 25.0g of water from 22.0 c to 30.8 c.
What would be the pressure of the gas, in kPa, if it were transferred to a container at 24°C whose volume is 55.0L?
Experiments have shown that for 1,2-dichloroethane, ClCH2CH2Cl, in carbon tetrachloride solution at 25 degrees, 70% of the molecules are in the "anti" and 30% are in the "gauche" conformation.
