Hey there!

Zn + HCl → ZnCl₂ + H₂

First, balance Cl.

1 on the left, 2 on the right. Add a coefficient of 2 in front of HCl.

Zn + 2HCl → ZnCl₂ + H₂

Next, balance H.

2 on the left, 2 on the right. Already balanced.

Lastly, balance Zn.

1 on the left, 1 on the right. Already balanced.

Our final balanced equation:

Zn + 2HCl → ZnCl₂ + H₂

Hope this helps!
