To determine if the reaction ( \text{Ni}_2\text{S}_2 \rightarrow 2\text{NiS} ) is spontaneous, we would need to consider the Gibbs free energy change (( \Delta G )) for the reaction. If ( \Delta G < 0 ), the reaction is spontaneous. Factors such as temperature, pressure, and the enthalpy and entropy changes of the system also play a crucial role in this assessment. Without specific thermodynamic data, it's not possible to definitively state the spontaneity of the reaction.

Nickel chloride silver nitrate molecular ionic and net ionic?
The molecular equation for the reaction between nickel(II) chloride and silver nitrate is NiCl2 (aq) + 2AgNO3 (aq) → 2AgCl (s) + Ni(NO3)2 (aq). The ionic equation is Ni2+ (aq) + 2Cl- (aq) + 2Ag+ (aq) + 2NO3- (aq) → 2AgCl (s) + Ni2+ (aq) + 2NO3- (aq). The net ionic equation is 2Ag+ (aq) + 2Cl- (aq) → 2AgCl (s).
What is the chemical formula for nickel (iii) sulfate?
