Plz help have no idea...

1- CuSO4 + AgNO3 ≥ Ag2SO4 + Cu(NO3)2

(double decomposition reaction)

2- CaCL2 + Mg ≥ Ca + Mgcl2

(single replacement)

3- Combustion

5- Al2S2 ≥ Al + S

(decomposition reaction)

6- Fe2O3 + Bacl2 ≥ Bao + Fecl3

(double decomposition reaction)

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.
