(a)
Interpretation:
The substance with larger dispersion forces needs to be determined.
C8H18, Octane, C2H6 and Ethane
Concept introduction:
Dispersion forces sometimes are known as London Forces, induced-dipole forces, van der Waals forces or London Dispersion forces. They are induced-dipole forces which develop from variations within the electron’s arrangement around the molecule. Even molecule which is non-polar will not contain the perfect dispersal of charge for every moment of time.
(b)
Interpretation:
The substance with larger dispersion forces needs to be determined.
HCl or HI

- Use the provided information to calculate Kc for the following reaction at 550 °C: H2(g) + CO2(g) ⇌ CO(g) + H2O(g) Kc = ?CoO(s) + CO(g) ⇌ Co(s) + CO2(g) Kc1 = 490CoO(s) + H2(g) ⇌ Co(s) + H2O(g) Kc2 = 67arrow_forwardCalculate Kc for the reaction: I2 (g) ⇋ 2 I (g) Kp = 6.26 x 10-22 at 298Karrow_forwardFor each scenario below, select the color of the solution using the indicator thymol blue during the titration. When you first add indicator to your Na2CO3solution, the solution is basic (pH ~10), and the color is ["", "", "", "", ""] . At the equivalence point for the titration, the moles of added HCl are equal to the moles of Na2CO3. One drop (or less!) past this is called the endpoint. The added HCl begins to titrate the thymol blue indicator itself. At the endpoint, the indicator color is ["", "", "", "", ""] . When you weren't paying attention and added too much HCl (~12 mL extra), the color is ["", "", "", "", ""] . When you really weren't paying attention and reached the second equivalence point of Na2CO3, the color isarrow_forward
