The standard cell potential (e°cell) for the voltaic cell based on the reaction below is v. sn2+ (aq) + 2fe3+ (aq) → 2fe2+ (aq) + sn4+ (aq) the standard cell potential (e°cell) for the voltaic cell based on the reaction below is v. sn2+ (aq) + 2fe3+ (aq) 2fe2+ (aq) + sn4+ (aq) +1.39 +1.21 +0.46 -0.46 +0.617
i think the answer is different frequency because i had this question but you might have a different picture but i think this is the answer.
have a good day!
that would be:
fe2o3 + 3h2 > 2 fe + 3h2o.
for example, nacl reacts with agno₃ to produce nano₃ and agcl (a precipitate). the chemical equation for this reaction will be:
nacl + agno₃ → nano₃ + agcl (s)
the complete ionic equation for the same reaction will be:
na⁺ + cl⁻ + ag⁺ + no₃⁻ → na⁺ + no₃⁻ + agcl (s)
excepting for the agcl solid, all other species in the ionic equation are written as ions.nacl exists as na⁺ ions and cl⁻ ions.agno₃ exists as ag⁺ ions and no₃⁻ ions.nano₃ exists as na⁺ ions and no₃⁻ ions.agcl does not dissolve in water. rather, its ions stay intact within the ionic lattice.
their subscripts show their charges. there's no subscript in the chemical equation. it takes some reasoning to tell the ions formed from each of the species.
