It depends on the equation.
Zn + 2HCl -> ZnCl ₂ + H ₂
4K + O2 = 2K2O so the "coefficient" is 1
Equation is Zn + Pb(NO3)2 --> Zn(NO3)2 + Pb

Zn + Ag2S -> 2Ag + ZnS
Br2 + Zn ----> ZnBr2
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.
It depends on the equation.
Zn + 2HCl -> ZnCl ₂ + H ₂
