Answer:
0.34
Explanation:
Cu>>>Cu2+(oxidation number increases)[Oxidation occurs]
Ag+>>>Ag(Oxidation number decreases) [Reduction occurs]
E°=0.80-0.46
=0.34V
Element with the same number of shells is element with the same period in periodic table,while element with the same numbers of valence electron is element in the same group .it also have similar chemical properties but different physical properties
Answer: difference in Vander Waals forces
Explanation:
The intermolecular force of attraction between the molecules in chlorine is WEAKER than that of Bromine.
This force is known as VANDER WAALS forces. And it DECREASES down the group; so Chlorine which is placed higher is a GAS, while Bromine placed lower in Group 7 is a LIQUID.
