Based on the boiling point elevation effect of a solution on a solvent what would you have expected to happen to the boiling point of your mixtures? did the observations match what you would have expected? Explain. My boiling point was 83.7C

The molal boiling point elevation constant K,=0.90 °C·kg mol 1 for a certain substance X. When 26. g of urea ((NH.),CO) CO are dissolved in 650. g of X, the solution boils at 137.9 °C. Calculate the boiling point of pure X. Be sure your answer has the correct number of significant digits. °C x10

What is a superstaturated solution? How would you prepare a supersaturated solution of a solid solute in a liquid solvent? How would you prepare a supersaturated solution of a gas solute in a liquid solvent?

A metal, M, of atomic mass 56 amu reacts with chlorine to form a salt that can be represented as MCly. A boiling point X• elevation experiment is performed to determine the subscript x, and therefore, the formula of the salt. A 34.6 g sample of the salt is dissolved in 100.0 g of water and the boiling point of the solution is found to be 377.34 K. Find the formula of the salt. Assume complete dissociation of the salt in solution. formula:

11. The heat of solution ( Δ Hsoln) is the algebraic sum of the heat of mixing (Δ Hmix), the heat of solvent (Δ Hsolvent) and the heat of solute  (Δ Hsolute).  Which of these four enthalpy changes can only be exothermic?                                  W) Δ Hsoln                   X) Δ Hmix                       Y) Δ Hsolvent                   Z) Δ Hsolute Group of answer choices A.) W B.) Z C.) Y & Z D.) X

A certain liquid X has a normal boiling point of 117.90 °C and a boiling point elevation constant K,= 1.09 °C·kg'mol Calculate the boiling point of a solution made of 95.g of sodium chloride (NaCl) dissolved in 900. g of X. Round you answer to 4 significant digits.

The heat of solution of potassium acetate (KC2H3O2) in water is -15.30 kJ/mol.If 15.90 g of KC2H3O2(s) is dissolved in 545.0 mL of water that is initially at 23.60 °C, what will be the final temperature (in degrees Celcius) of the resulting aqueous solution?(Assume no heat exchange with the surroundings.)

A 70.0% alcohol solution is used as an antiseptic to clean hoods in microbiology labs. What volume of this solution will contain 10.0 g of alcohol?
