The reaction of copper metal with silver ions in a solution if silver nitrate is spontaneous . Calculate she standard cell potentiom to show that this is so. From the cell potential calculate the value if the equilibrium constants for the reaction at 15 C. From the equilibrium constant or the reaction , calculate the standard free energy change for the reaction . Indicate clearly how these. Three quantities are related
What is the entropy change for freezing 4.25 g of C2H5OH at 158.7 K? H = -4600 J/mol. Answer in units of J/K.
Predict the sign of Change in S for this reaction and explain. -Calculate the Change is S from standard molar entropy values. S for Na2O2(s) = 95 J/mol K
A solution of 0.2113 g of water dissolves in 25.0 g of a solvent which freezes at 11.5 EC below the freezing point for the pure solvent. What is the Kf value for this solvent?
Calculate the number of moles of O2 required to react with phosphorus to produce 5.50 g of P4O6. (Molecular mass P4O6 = 219.9 g/mol.)
why is it important that none of the solid CaCl2 be included in the final distillation of 1-bromobutane?
Write a paper on an article and it shows many different compounds and need a better understanding of where each originated and what steps were made in their synthesis.
Organic hydrogenation reactions, in which H2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries.
