Question

Which equation represents a conservation of charge? A) 2Fe3+ + Al 2Fe2+ + Al3+ B) 2Fe3+ + 2Al 3Fe2+ + 2Al3+ C) 3Fe3+ + 2Al 2Fe2+ + 2Al3+ D) 3Fe3+ + Al 3Fe2+ + Al3+

Answer 1

D

Step-by-step explanation:

The AI generated answer is incorrect this update is very bad... The total charge of the reactants for option D is +9 because Al is by itself, meaning it has a charge of 0. (The AI said the total charge of the reactants was +10 which is wrong)

Answer 2

Answer: D

Explanation:

3Fe^3+ + Al ---> 3Fe^2+ + Al^3+

Total charge of reactants = 3 x +3 = +9

Total charge of products = (3 x +2) + (+3) = +9
