Arrange Ag, Mg, K in acitivity series.

Ag and Cu are below hydrogen in activity series, yet they are found in combined state. Why?

The work functions of Ag, Mg, K and Na respectively in eV are 4.3, 3.7, 2.25, 2.30. when an electromagnetic radiation of wavelength of 300 nm is allowed to fall on these metal surfaces, the number of metals from which the electrons are ejected is. (1 eV = 1.6022 times 10^-19 J)

The E^(ɵ) for Cl_2//Cl^(-) is + 1.36, for I_2 //I^(-) is + 0.53, for Ag^(+)//Ag is + 0.79, Na^(+)//Na is -2.71 and for Li^(+)//Li is -0.35 . Arrange the following ionic species in decreasing order of reducing strength : I^(-), Ag, Cl^(-), Li, Na

Arrange in the given order: Increasing IE_1 :Na , K and Rb

Among N^(-3), O^(-2), F^(-), Na^(+), Mg^(+2) and Al^(+3) (b) Arrange them in the increasing ionic radii.

Arrange the following in the descending order of magnitude (A) [I xx j j xx k k xx i] (B) [I + jj + k k + i] (C ) (I xx j) (j xx k) (D) (K xx j) (k xx j)

Parenchyma cells are associated with acitivity like

Arrange the following metals in the order of their decreasing reactivity, Fe, Cu, Mg, Ca, Zn, Ag
