which of the following has the highest boiling point? a)C2Cl6 b)C2Br6 c)C2H6 d)C2F6 e)C2I6 i know its e, but why is that the answer? are all questions about boiling points similar? or they they have to do with intermolecular forces? i have a test soon on
Arrange the following 0.10M solutions in order of increasing pH: a. Nacl b. NH4CL C. HCL D. NaCH3CO2 e. KOH
The enthalpy of vaporization of chloroform (CHCl3) is 29.2 kJ mol-1 at its normal boiling point 61.2 Celsius. what is the standard change in entropy for vaporization of chloroform at its normal boiling point? Answer I got was 29.2/334.2 = 0.0873.
Two HVAC technicians are discussing the properties of water.Technician A says that if the pressure of water is raised,the boiling point will decrease.Technician B says that placing water in a vacuum will cause its boiling point to increase.Which of the
At a pressure of 1ATM, _____ KJ of heat is needed to vaporize a 32.3 g sample of liquid ethanol at its normal boiling point of 78.4 C. Boiling point (78.4 C), specific heat (2.46 J/g C), and Hvap(78.4 C)=38.6 KJ/mol are provided. Please include how to
The heat of vaporization of benzene, C6H6, is 30.8kJ/mol at its boiling point of 80.1 degrees celsius. How much energy in the form of heat is required to vaporize 102g of benzene at its boiling point? I know that the answer is 24.2kJ but i am not sure how
Solve: 6C3 (1 point) 120 720 20 240 2. Which is not a combination? (1 point) choosing 3 toppings for your pizza lining 3 students up in a row choosing 2 desserts from a tray of 10 choosing 5 students to represent a class of 30 3. How many ways can you
The molal boiling-point constant for water is 0.51 degrees C/molal. The boiling point of a 1.00 molal solution of Ca(NO3)2 should be increased by: A.) exactly 1.53 or B.) Somewhat less than 1.53 This is how I worked the problem: Ca(NO3)2 dislocates into 3
Why is CH3I have a higher boiling point than CH3Cl? I thought, since Cl is more electronegative, it withdraws more electron density to its part and hence increase dipole movement within the atom and hence, requiring more energy to split them up and that
From the following: pure water solution of C12H22O11 (m=0.01) in water solution of NaCl (m=0.01) in water solution of CaCl2 (m=0.01) in water choose the one with the a) highest freezing point b) lowest freezing point c) highest boiling point d) lowest
