He standard cell potential (E° cell) for the voltaic cell based on the reaction below is V. Sn 2+ (aq) + 2Fe 3+ (aq) → 2Fe 2+ (aq) + Sn 4+ (aq)

The options in the question are:

a) +0.46 V

b) +0.617 V

c) +1.39 V

d) -0.46 V

e) +1.21 V

b) +0.617 V

Explanation:

The equation shows that the anode is Sn2+/Sn4+ while the cathode is Fe3+/Fe2+.

The E° cell is obtained from E°cathode - E°Anode

E°cathode= 0.154V

E°Anode= 0.771V

E° cell= E°cathode - E°Anode= 0.771-0.154=0.617

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
