Calculate the concentration of I- in a solution obtained by shaking 0.10 M KI with an excess of AgCl.
Devise tests which allow you to distinguish between the ions in each case.
Draw the two chairs (chair 1 and chair 2) conformers of trans-1-methyl-3-isopropylcyclohexane and indicate which one is the most stable. Draw the Newman projection of the most stable conformation
You dissolve 12.6352 g of potassium iodide in water and bring the volume of solution to 250.0 ml. What is the molar concentration of KI and what volume of 0.0436 molar hydrochloric acid is required to react with 30.0 ml of 0.0278 molar LiOH?
A 1.80 g sample of a large boimolecule was dissolved in 18.0 g of carbon tetrachloride. The boiling point of this solution was determined to be 77.85°C. Calculate the molar mass of the biomolecule.
How much heat is required to vaporize 25.5 g of water at 100 C? The heat of vaporization of water at 100 C is 40.7 rm kJ/mole.
