Answer:
Explanation:
reduction potential of NO gas is highly unfavourable . It is - 1.7 V . So it is highly unlikely to be reduced to NO⁻ . On the other hand it is easily oxidised .
Half cell reaction of given cell
At anode ( where oxidation occurs )
NO⁻ ⇒ NO + e ( reduction potential is - 1.7 V )
At cathode ( where reduction takes place )
Br₂ + 2e ⇒2 Br⁻ ( reduction potential is 1.09 V )
(NO⁻ ⇒ NO + e ) x 2
Br₂ + 2e ⇒2 Br⁻
--------------------------------
Br₂ + 2NO⁻ ⇒ 2NO +2 Br⁻
Ecell = Ecathode - E anode
= 1.09 - 2 x ( - 1.7)
4.5 V

Hello there!
In this case, according to the given information, it turns out possible for us to calculate the number of silver atoms in 330 grams of a silver bracelet by knowing 1 mole of silver has a mass of 108 grams and also contains 6.022x10²³ atoms; thus, the mathematical setup is shown below:
Which is equal to:
