CS2 of ten milligrams mixes with excess of Cl2 gas the heat evolved is transferred without loss to 6.450 grams of H2O at the temperature of 22.0 degree Celsius determine the final temperature of the water ?
Heat of vaporization of Benzene =30.72kJ/mol , normal boiling point = 80.1 degrees Celsius. Determine At what temperature does C6H6 boil when the external pressure = 470 torr?
Calculate the number of grams of NaOH per 100ml to give a pH8.0 solution if pure water at pH7.0 is used in the experiment. Repeat this calculation for a pH6.0 solution using HCl.
Why does aluminum hydroxide readily dissolve in concentrated NaOH but not in concentrated NH3? Please give a thorough explanation, not just a short answer.
