How do you balance the chemical equation for the single-replacement reaction of zinc and hydrochloric acid to generate hydrogen gas
The net ionic equation for the dissolution of zinc metal in hydrobromic acid is as follows: Zn (s) + 2H+ (aq) ----> Zn2+ (aq) + H2 (g).
Zn(s)+2HBr(aq)--->ZnBr2(aq)+H2(g)
2 Zn + 2 HCL --> H2 + 2 ZnCl
Zn(NO3)2 + Na3PO4 yields Zn3(PO4)2 + NaNO3 with zinc phosphate being the precipitate.
Zn(s) + 2HCl(aq) -> ZnCl2(aq) + H2(g)
word equation is: iron sulphate + zinc = zinc sulphate + iron
Zn + 2HCl = ZnCl2 + H2
2ZnO
Cu3N2
2Zn3O2
The valence of zinc is 2+.
Zn + 2HCl -> ZnCl ₂ + H ₂
Zinc Oxide(aqeous) + Carbon(solid) -> Zinc(g) + Carbon Monoxide(g) ZnO + C -> Zn + CO - this is also balanced equation.
The carbonates that can be thermally decomposed . They form metal oxides and carbon dioxide. When white zinc carbonate powder when heated forms yellow/white zinc oxide and carbon dioxide gas: the balanced equation for zinc carbonate--------carbon dioxide zinc oxide is :ZnCO3 → ZnO + CO2
Equation is Zn + Pb(NO3)2 --> Zn(NO3)2 + Pb
This is a single replacement reaction. Zinc is more reactive than copper, so it replaces it and bonds with sulfate. The balanced equation is Zn + CuSO4 => Cu + ZnSO4 (zinc always has a charge of +2)
2AgNO3 + ZnI2 -> 2AgI + Zn(NO3)2
P = CqB^2
2CH3COOH + Zn =(CH3COO)2Zn + H2
