Why can you only suggest causation in a true experiment?

 For the reaction             2 C4H10 (g) + 13 O2 (g) → 8 CO2 (g) + 10 H2O (g) ΔH° is -125 kJ/mol and ΔS° is +253 J/K ∙ mol. This reaction is ________.  

The standard cell potential (E°cell) of the reaction below is +0.126 V. The value of for the reaction is ________ kJ/mol.             Pb (s) + 2H+(aq) → Pb2+ (aq) + H2 (g)
