Which one of the following substances is soluble in benzene? Group of answer choices Naphthalene (C10H8)...
A 2.50 g sample of naphthalene, C10H8, was dissolved in 100 g of benzene. What is the freezing point of the solution? The freezing point of pure benzene is 5.45 degrees Celsius; Kf=5.07 degrees Celsius/m. The molar mass of C10H8 is 128.17 g/mol The answer is supposed to be 4.46 degrees Celsius. How did they get there?
Consider 1.00 mole of each of the following substances: 1) NaCl (sodium chloride) 2) CaCl2 (calcium chloride) 3) CH3OH (methanol) 4) Naphthalene (C10H8) Answer the following questions: A) Which one of the above substances would likely not change the freezing point of water at all? Explain. B) Which one of the above substances would likely lower the freezing point of water the most? Explain.
1) The molarity of naphthaline in a solution of naphthalene (C10H8, MW = 128.8), a non-ionizing and nonvolatile solute, and benzene (CH, MW = 78.11), a volatile solvent, is (C10Hg] =0.086 M. The density of the solution is D = 0.8748 g/cm. Find the following: a) The osmotic pressure exerted by the solution, at T = 25.0 °C. Give your final answer in units of torr.

1) One of these statements is incorrect. Which one? Group of answer choices Energy is the capacity to do work or transfer heat. Exothermic processes transfer heat from the surroundings into the system. Endothermic processes have a positive ΔH value. Energy is neither created nor destroyed in chemical reactions. 2) Choose the compound from the set that can be classified as a salt. Group of answer choices sodium hydroxide (NaOH) acetic acid (CH3CO2H) glucose (C6H12O6) magnesium bromide (MgBr2) 3) Which...
