i'm trying balance this equation, but not sure i'm right
Balance the following equation: Zn+HCl→ZnCl+H2
will this be the right answer?
Zn+2HCl→ZnCl+H2

you will need 2 chlorine
Zn+(aq) + 2HCL(aq) = ZnCl2(aq) + H2(g)

Zn+HClâZnCl+H2
1.) You need 2 Hydrogen... so get 2 HCl.
Zn+2HClâZnCl+H2
2.) Now you have 2 Cl on the left, so you need it on the right. Double the ZnCl.
Zn+2HClâ2ZnCl+H2
3.) Now you have 2 Zn on the right, so you need it on the left. Double the Zn.
2Zn+2HClâ2ZnCl+H2 (solution!)
However, Zinc Chloride is ZnCl2, not ZnCl. To balance it for ZnCl2, it would be:
Zn + 2HCl â ZnCl2 + H2

NO...
Zn + 2Hcl = Zncl2 + H2

the valency of Zn is 2 and so
Zn+2HCl=ZnCl2+H2
