Consider the reactions of cadmium with the thiosulfate anion. Cd2+(aq) + S2O32–(aq) Cd(S2O3)(aq) K1 = 8.3 × 103 Cd(S2O3)(aq) + S2O32–(aq) Cd(S2O3)22–(aq) K2 = 2.5 × 102 What is the value for the equilibrium constant for the following reaction? Cd2+(aq) + 2S2O32–(aq) Cd(S2O3)22–(aq)

Which is a difference between molecular compounds and ionic compounds? select the correct answer below: question 5 options: molecular compounds typically form between a metal and a nonmetal, while ionic compounds typically form between nonmetals. molecular compounds result from the transfer of electrons between atoms to form ions, while ionic compounds result from the sharing of electrons between neutral atoms. molecular compounds are formed of discrete, neutral molecules, while ionic compounds are formed of large repeating arrays of opposite charges. molecular compounds have high melting points and high boiling points, while ionic

Can someone me with 3 and 4 plz. this is for masteries test.

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.
