Problem #10: 2.60 grams of a compound know to contain only indium and chlorine is dissolved in 50.0 g of tin (IV) chloride (K b = 9.43 °C kg mol¯ 1). The normal boilng point is raised from 114.1 °C for pure SnCl 4 to 116.3 °C for the solution.
1) In order to answer this question, we need to know the boiling point of SO 2. Looking it up, we find 14 °C, which converts to 263 K. 2) Warm the liquid to its boiling point: q = (mass) (Δt) (spec. heat) q = (98.1 g) (63 °C) (1.36 J/g °C) q = 8405.208 J. 3) Vaporize the liquid: q = (moles) (molar heat of fusion)
30 Ιαν 2024 · C programming Exercises, Practice, Solution: C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations.
Potassium iodide (KI) is prepared by reacting potassium hydroxide to iodine with a hot solution. It is used mainly in the form of a saturated solution, 100 g potassium iodide to 100 ml water. That equates to around 50 mg/drop.
The table below shows the normal boiling points of several substances. Write a program that prompts the user for the observed boiling point of a substance in °C and identifies the substance if the observed boiling point is within 5% of the expected boiling point.
Explain what the term "colligative" means, and list the colligative properties. Indicate what happens to the boiling point and the freezing point of a solvent when a solute is added to it. Calculate boiling point elevations and freezing point depressions for a solution.
An aqueous sucrose (C 12H 22O 11) solution of unknown concentration is found to have a freezing point of -0.912 oC. What is the normal boiling point and the partial pressure (in torr) of water at 25oC of this solution. Sucrose is a non-volatile, non-electrolyte. [BP =100.25oC; P H2O=23.59 torr] 4. Pure 2-methyl-2-propanol has a freezing point ...
