Identify the reactant oxidized and the reactant reduced in the following equations: a. NI(s)+Pb2+(aq) = Pb (s) + NI2+(aq)

FeSO4(aq) + Mg(s) → Fe(s) + MgSO4(aq)

Cl2(g) + 2 K(s) →2 KCl(s)

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.

There is no reason to think the results are biased or not conducted properly but you should not assume the results are correct just because they were done in a laboratory so the answer would be c. it is likely to be reliable because the results support the conclusion presented.

The answer for this is a
