Concept explainers
Interpretation:
Boiling point of argon has to be estimated.
Concept Introduction:
Elements with same valence electrons are placed in the same group in periodic table
Chemical properties of an element can be determined by the number of electrons in the subshell containing the outermost electrons.
The elements with same number of valence electrons have physical and chemical properties.
Noble gases are inert gases with completely filled electronic configuration. Helium, neon, argon, xenon, krypton, and radon are the noble gases.
Group 8A in the periodic table contains 8 valence electrons and the outer electronic configuration of noble gases is
Boiling point: It is the temperature at which liquid converts to vapor. At boiling point the vapor pressure of liquid and the pressure of the surroundings are equal.

- A concentration cell consists of two Sn/Sn2+ half-cells. The cell has a potential of 0.10 V at 25 °C. What is the ratio of [Sn2+] (i.e., [Sn2+left-half] / [Sn2+right-half])?arrow_forwardElectrochemical cell potentials can be used to determine equilibrium constants that would be otherwise difficult to determine because concentrations are small. What is Κ for the following balanced reaction if E˚ = +0.0218 V? 3 Zn(s) + 2 Cr3+(aq) → 3 Zn2+(aq) + Cr(s) E˚ = +0.0218 Varrow_forwardConsider the following half-reactions: Hg2+(aq) + 2e– → Hg(l) E°red = +0.854 V Cu2+(aq) + 2e– → Cu(s)E°red = +0.337 V Ni2+(aq) + 2e– → Ni(s) E°red = -0.250 V Fe2+(aq) + 2e– → Fe(s) E°red = -0.440 V Zn2+(aq) + 2e– → Zn(s) E°red = -0.763 V What is the best oxidizing agent shown above (i.e., the substance that is most likely to be reduced)?arrow_forward
