Please help me with this chemistry question. Image attached.

Moles of zinc chloride produced are 0.09942 moles.

Explanation:

Mass of zinc used = 6.5 g

Moles of zinc =

According to reaction, 1 mol of zinc gives 1 mole of zinc chloride,then 0.09942 moles of zinc will give :

of zinc chloride

Moles of zinc chloride produced are 0.09942 moles.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
