Question
Identify the electrodes and the direction of electron flow. a is Ag, c is Cu and electrons flow from a to c. a is Cu, c is Ag and electrons flow from a to c. a is Ag, c is Cu and electrons flow from c to a. a is Cu, c is Ag and electrons flow from c to a. For add solutions of the same molarity add strength is proportional to the equilibrium concentration of H_3O^+. For equimolar solutions of adds, which equilibrium expression be corresponds to the strongest acid? K_c = [H_3O^+] [NO_2^-1] / [HNO_2] = 4.5 Times 10^-4 A solution of LiCl in water has XLiCl = 0.0500. What is the molality? Which of these neutralization reactions has a pHExplanation / Answer
Answer:
15). B). a is Cu, c is Ag and electrons from c to a.
16).
B) or D).Unable to view Kc value for B-option.
In genaral high value of Kc indicates the strength of an acid.
Among the given Kc values Option D). posses lowest Kc value, so it is the expression corresponds to strong acid.
18). The solution which is formed by the reaction strong acid and weak base will posses pH less than 7.
D). HCl + C5H5N C5H5NHCl
will have pH less than 7
