Predict whether each of the following reactions contains mostly
reactants or products AT EQUILIBRIUM
the formulas are :
CO3^2- (aq) + H2O (l) <---> HCO3^-)aq) + OH^- (aq)
NH4^+(aq) + OH^- <-->NH3 (aq) +H2O(l)
H2S (aq) + F^-(aq)+HS^-(aq)
please do not break apart the formulas and tell me what is the
product and reactant like the previous person did. I want to know
which formula is which at equalibrium as a whole formula
Predict whether each of the following reactions...
