Indicate what reaction is happening at the anode, and for the reaction below, which species would be the anode? Sn(s) + 2 Ag⁺(aq) → Sn2+(aq) + 2 Ag(s)

Sn --> Sn2+ + 2e-

Explanation:

At anode oxidation reaction occur. In this reaction Sn is getting oxidized to state +2 while Ag is reduced from +1 to 0.

Hence, reaction at anode will be  

Sn (s) --> Sn2+ (aq) + 2e-

At cathode the following reaction occur

2 Ag⁺ + 2e- ---> 2Ag (s)

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
