Answer :
2.12 grams of zinc can be deposited on a steel tank from a ZnSO₄ solution when a 0.855-A current flows for 2.50 days.
What is Balanced Chemical Equation ?
The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.
Now write the balanced chemical equation :
Zn(s) + 2AgN0₃(aq) → Zn(NO₃)₂(aq) + 2Ag(s)
What is Stoichiometry ?
Stoichiometry helps us use the balanced chemical equation to measure quantitative relationships and it is to calculate the amount of products and reactants that are given in a reaction.
[tex]Ag(\frac{1 mol Ag}{107.9 g Ag})(\frac{1 mol Zn}{2 mol Ag})(\frac{65.39 g Zn}{1 mol Zn}) = 0.303 AgZn[/tex]
Mass of remaining Zn = 2.5 g Zn - 0.303 g Zn
Mass of strip = 3.37 = Ag produce + Zn remaining
3.37 g = Ag Ag+ (2.5 g Zn - 0.303 Ag Zn)
A = 1.25 g → mass of Ag produced
Mass of Zn remaining = 3.37 g - 1.25 g = 2.12 g
Thus from the above conclusion we can say that 2.12 grams of zinc can be deposited on a steel tank.
