Question

Insert the appropriate sign (<, >, or =) comparing the quantity described in the leftmost column. Numerical value: 4 [Select] 7 Rate of diffusion: F2 [Select] Br2 Oxidation number of chlorine: C104. [ Select] CIF45 Average kinetic energy at 298 K: CO2 [ Select] A NO2 AHºf (not the magnitude!) of the following made-up compound: AZ2 (s) [Select] A AZ2 (g) Number of electrons: Mg2+ [Select ] 52-

Answer 1

numerical value 4   7 ;

rate of diffusion F₂   Br₂ ( rate of diffusion is inversly proportional to molar mass.);

Oxidation number of Cl ClO₄^- ( Cl have +7 oxidation state ) ClF₄^- ( Cl have +4 oxidation state .).;

Average kinetic energy at 298 K CO₂ = NO₂ (Average kinetic energy is only dend on temperature and moles of gas);

$\Delta$H_f^o for AZ₂(S) AZ₂(g) ;

Number of Electrons Mg²⁺ S^2- ;;
