It is a single displacement reaction. No balancing is needed in the resulting equation.
Zn + CuBr2 ----> ZnBr2 + Cu
Zn (s) + Cu (s) -> N.R.
The balanced equation is as follows: Zn(s) + 2HCl(aq) --> ZnCl2(aq) + H2(g)
Zn+ H2O ---> ZnO + H2 Zn+ H2O ---> ZnO + H2
Equation is Zn + Pb(NO3)2 --> Zn(NO3)2 + Pb
zinc and hydrochloric acid
double replacement
Zn + CuBr2 = Cu + ZnBr2
Zn + CuSO4 --> ZnSO4 + Cu
The net ionic equation is Zn + 2H+ --> Zn2+ + H2
The balanced equation is as follows: Zn(s) + 2HCl(aq) --> ZnCl2(aq) + H2(g)
Zn+ H2O ---> ZnO + H2 Zn+ H2O ---> ZnO + H2
Br2 + Zn ----> ZnBr2
If you want to balance the equation, then: 2Zn + O2 --> 2(ZnO)
No. This equation is not balanced and does not even represent any reaction. The equation for the actual reaction between elemental zinc and chlorine is: Zn + Cl2 => ZnCl2.
Equation is Zn + Pb(NO3)2 --> Zn(NO3)2 + Pb
Zn(s) + 2HCl(aq) ---> ZnCl2(aq) + H2(gas)
zinc and hydrochloric acid
