Mg + KCl
Cu and ZnCl2 are being produced.
When hydrochloric acid reacts with potassium chloride, it yields potassium chloride and water. The chemical equation is: HCl + KCl -> KCl + H2O.
The balanced equation for BaCl2 + K2SO4 -> BaSO4 + 2KCl is BaCl2 + K2SO4 -> BaSO4 + 2KCl.
The correct balanced chemical equation for the reaction between zinc (Zn) and hydrochloric acid (HCl) is: Zn + 2HCl → ZnCl2 + H2 This reaction produces zinc chloride (ZnCl2) and hydrogen gas (H2).
the chemical equation for zinc plus cupric sulfate equals zinc sulfate plus copper can be written in the form of reaction as follows .ZN +Cu SO 4 -> Zn SO 4 + Cu.they form a aqueous solutions.
Zn(s) → Zn2+(aq) + 2e- and Fe3+(aq) + e- → Fe2+(aq)
Zn2+ + 2e- <--> Zno -0.7618 V
Cl2(g) + 2KI --> 2KCl(aq) + I2(s)
2Zn(s) + 2HCL (aq) --> 2ZnCl + H2 (g) The reactants are zinc (Zn) and hydrochloric acid (HCl).
The balanced chemical equation for the reaction is: Zn(s) + CuSO4(aq) -> ZnSO4(aq) + Cu(s)
