(1) atomic numbers

Explanation:

The observed regularities in the properties of the elements on the periodic table are periodic functions of their atomic numbers.

  • Atomic number is the number of protons in an atom.
  • The periodic law states that "the properties of elements are a periodic function of their atomic number".
  • Elements on the periodic table are arranged based on the atomic numbers they contain.

Sodium carbonate can be made by heating sodium bicarbonate: 2NaHCO3(s) → Na2CO3(s) + CO2(g) + H2O(g) Given that ΔH° = 128.9 kJ/m
Ad libitum [116K]

Answer:

[tex]128^{o}C[/tex]minimum temperature will the reaction become spontaneous.

Explanation:

\Delta G=\Delta H-T \Delta S

From the given,

\Delta G^{o}=33.1

\Delta H^{o}=128.9kJ/mol

Temperature\,change=25+273=98K

33.1=128.9-298 \Delta S

\Delta S=0.322kJ/mol.K

\Delta G=\Delta H-T \Delta S

0=128.9-T(0.322)=401K=218^{o}C

Therefore, 128^{o}Cminimum temperature will the reaction become spontaneous.
