Question:
For the following problems, you’ll be dealing with fictional elements again (in addition to hydrogen, oxygen, sodium). These fictional elements all main-group elements, so you can apply what you know about those elements to these fictional elements. The properties of these elements are shown in the table below. For any problems involving calculations, you must show all work to receive credit.
Element | Name | valence electrons | Mass (amu) | electro-negativity | cp, gas(J/g*K)* | cp, liquid(J/g*K)* | cp, solid(J/g*K)* | m.p.* (K) | b.p.* (K) |
Ct | Cattium | 6 | 305.6 | 2.51 | 0.51 | 1.22 | 3.41 | 240.2 | 303.1 |
Px | Purrium | 7 | 310.1 | 3.32 | 1.32 | 2.10 | 4.00 | 199.8 | 355.5 |
Ny | Noodline | 6 | 299.2 | 3.46 | 1.46 | 2.79 | 4.52 | 174.2 | 298.1 |
Ff | Fluffygen | 5 | 303.4 | 2.99 | 0.99 | 1.88 | 3.02 | 180.5 | 277.0 |
Ws | Whiskerine | 4 | 301.9 | 2.62 | 0.62 | 1.35 | 2.96 | 472.2 | 649.9 |
Cw | Clawium | 7 | 297.0 | 4.42 | 1.89 | 2.74 | 3.77 | 202.2 | 378.0 |
- A 526-g sample of Ct2 was cooled from 78.5 degrees Celsius to -15.0 degrees Celsius. The resulting energy change was transferred to a 2.500-L sample of liquid water, resulting in a temperature change of 6.88 degrees Celsius (you may assume no heat was lost and that the density of water remained constant at 02 kg/L). What is the enthalpy of vaporization of Ct2, in kJ/mol?
