When the oxide of generic metal m is heated at 25.0 °c, only a negligible amount of m is produced. o2m(s ----> m(s o2(g delta
Len [333]
(1) MO₂(s) + C(s) → M(s) + CO₂ (g),  ΔG₁ = 288.9 kJ/mol
(2) C(s) + O₂(g) → CO₂(g),   ΔG₂ = -394.4 kJ/mol
By adding both equations 1 + 2 we get the coupled reaction:
MO₂(s) + 2 C(s) + O₂(g) → M(s) + 2 CO₂(g)
ΔG⁰ = ΔG₁ + ΔG₂ 
       = 288.9 + (-394.4) = -105.5 kJ/mol = -105500 J/mol
Temperature T = 25 + 273.15 = 298.15 K
Molar gas constant R = 8.314 J/mol.K
K = e^{ \frac{-dG0}{RT} }
   = e^{ \frac{105500}{8.314 x 298.15} } 
    = 3.05 x 10¹⁸

Identify the precipitation reactions. drag the appropriate items to their respective bins.
lana66690 [7]
I can't fully answer this question because it is incomplete. In order for me to help you, I could just define what a precipitation reaction is and give a concrete example.

A precipitation reaction consists of two aqueous solutions that when reacted together, forms an insoluble salt. For example, 

AgNO₃ (aq) + HCl (aq) --> AgCl (s) + HNO₃ (aq)

In this case, the precipitate is AgCl, Silver Chloride, which appears as a white solid.
