kherson [118]

Answer:When a strontium atom loses two electrons, it becomes a(n) cation with a charge of 2+. when any neutral atom loses an electron it becomes cation that is positively charged ions and an ion gets the charge according to the number of electrons loses.

you are very welcome but I may be inaccurate.

The value of ΔG° at 221.0°C for the formation of phosphorous trichloride from its constituent elements, P2(g) + 3Cl2(g) → 2PCl3(
densk [106]

Answer:

ΔG    = - 590.20 kJ/mol

Explanation:

The formula for calculating Gibb's Free Energy  can be written as:

ΔG    =    ΔH - TΔS

Given That:

ΔH = -720.5 kJ/mol

T = 221.0°C = (221.0 + 273.15) = 494.15 K

ΔS° = -263.7 J/K

So; ΔS° = -0.2637 kJ/K if being converted from joule to Kilo-joule

Since we are all set, let replace our given data in the above equation:

ΔG    =  (-720.5 kJ/mol) - (494.15 K) ( - 0.2637 kJ/K)

ΔG    =  (-720.5 kJ/mol) - (- 130.30755)

ΔG    =  -720.5 kJ/mol + 130.30755

ΔG    =  -590.192645 kJ/mol

ΔG    = - 590.20 kJ/mol

Thus, The value of ΔG° at 221.0°C for the formation of phosphorous trichloride from its constituent elements, P2(g) + 3Cl2(g) → 2PCl3(g) is <u>-590.20</u> kJ/mol.
