Calculate AGº for the following reaction in kJ/mol. (Use the smallest whole number coefficients possible when balancing the overall reaction.) A (8) + B2+ (1.0 M) → A3+ (1.0 M) + B(s) Half-reaction E A3+ + 3e A 2.99 B2+ + 2e → B -2.65 work to receive nartial credit)
Balance the reaction shown below using the smallest possible whole-number coefficients if the reaction is carried out under basic conditions. Make sure that every reactant and product has a coefficient in front of it (even if the coefficient is 1). You will need to add water to one side of the reaction equation in order to balance it. Now pick the correct statement about your balanced reaction equation from the multiple choices. Cl2O7(aq) + C2O42-(aq) Cl -(aq) + CO2(g) a)...
