It is fresher because of new transportation techniques and refrigerated trailers.
The correct answer is option B. i.e. E°cell > 0 = spontaneous reaction.
The spontaneous reactions always have positive voltage and the energy released in the reaction is used up to do work.

Hello there, my fellow human being!

2NaOH + ZnCl2 → 2NaCl + Zn(OH)2
Zn(OH)2 is your precipitate.
No. of moles of NaOH = 2.50X50.0÷1000 = 0.125mol
2mol of NaOH reacted to produce 1 mol of Zn(OH)2.
No. of moles of Zn(OH)2 produced when 0.125mol of NaOH reacted
= 0.125 x 1 ÷ 2
= 0.0625mol
Mass of Zn(OH)2 = 0.0625 x [65.4+2(16+1)] = 6.21g
