130.8 g Zn element is reacting with excess amount of HCl aqueous solution. According to this reaction, which of the followings is wrong (Hint: Zn takes +2 charge in its compounds. Zn: 65.4 g/mol) A) Chemical formula of the produced compound is ZnC12. B) 2 gr H2 gas is produced C) 4 moles of HCI is required to consume all zinc. Balanced reaction is: Balanced reaction is: Zn +2 HCl(suda) → ZnCl2 + H2 D) E) One of the products is zinc chlroide
