Which half reaction is associated with the anode? Sn(s) Sn2+ (aq) + 2e
O Sn2+ (aq) + 2e --> Sn(s)
O Pb2+ (aq) + 2e7
>Pb(s)
O Pb(s)-> Pb2+ (aq) + 2e

Which three statements represent the benefits of performing experiments using computer simulations?

Consider the reaction: 2al(s) + fe2o3(s) → al2o3(s) + 2fe(s) the δhf for fe2o3(s) = -824.3 kj/mole. the δhf for al2o3(s) = -1675.7 kj/mole. finish the equation. δhrxn = [(1)( kj/mole) + (2)( kj/mole)] - [(1)( kj/mole) + (2) ( kj/mole)]
