Jun 17, 2018 · Explanation: Boiling Point of BiH₃ is -16.8 °C. Boiling Point of SbH₃ is -18.4 °C. Boiling Point of NH₃ is -33 °C. Boiling Point of AsH₃ is -62.4 °C. Boiling Point of PH₃ is -87 °C. As we go down the group of Nitrogen family in the periodic table, the boiling point increases due to the effect of Van der Walls force but the ...
May 14, 2023 · The specific name given to the constant temperature at which a substance changes its phase from solid to liquid is called the melting point. The correct answer is option c) Melting Point. Explanation: The specific name given to the constant temperature at which a substance changes its phase from solid to liquid is called the melting point.
Sep 18, 2023 · Ethanol will have a relatively high boiling point. Acetic Acid: Like ethanol, acetic acid can also form hydrogen bonds due to the presence of the carboxyl (-COOH) group. It will have a higher boiling point than compounds without hydrogen bonding. Propanone (Acetone): Propanone can't form hydrogen bonds but can have dipole-dipole interactions.

Jul 7, 2019 · Calculate the molal boiling point constant for chloroform from the fact that its boiling point 61.2degree celciuse and .1 molal solution of an organic substance in chloroform boiled at 61.579degree celciouse
Jun 11, 2021 · Boiling point: −13 °C (9 °F; 260 K) Properties of SnH4. Chemical formula: SnH4. Molar mass: 122.71 g ...
Jan 29, 2020 · What is boiling point: The boiling point of a liquid is the temperature at which it begins to boil. For example, at a pressure of 1 atm, the boiling point of water is 100°C. The boiling point of a liquid is determined by three factors: temperature, air pressure, and the liquid's vapour pressure. Boiling point of: SnCl₄ - 114.15 °C; Gecl₄ ...
Answer:The boiling point of a solution prepared by adding 15 gram of nacl to 250 gram of water 373.53 K. Explanation: Mass of NaCl = 15 g. Weight of the solvent = 250 g. Boiling point of water = 373 K . boiling point of solution = T. K_b = 0.52 K kg/mol
Feb 28, 2023 · Obviously, elevation in boiling point is a colligative property. Hence, the required answer is, option (1) Both A and R are true and R is the correct explanation of A. Lowering of vapour pressure elevates the boiling point, which is directly proportional to the mole fraction of solute in the solution. Therefore it is a colligative property.
Oct 19, 2018 · The enthalpy change when 28 g carbon monoxide vaporizes at normal boiling point = 6.04 KJ/mole. and The enthalpy change for 2.38 g of carbon monoxide vaporizes at normal boiling point = Therefore, the enthalpy change is 0.514 KJ.
