are these already balanced?

CuSO4 + Zn ---> CuZn + SO4

AgNO3 + NaCl ---> AgCl + NaNO3

AgNO3 + NaCl ---> AgCl + NaNO3

CuSO4 + Zn ---> Cu + ZnSO4 is the correct equation I know how to balance equations but im not sure about these

Yes, they are balanced. But you really don't need to ask because you can check. I always check to make sure an equation is balanced.

For AgNO3 + NaCl ==> AgCl + NaNO3.

I see 1 Ag on the left and 1 Ag on the right.

I see 1 N on the left and 1 N on the right.

I see 3 O on the left and 3 on the right.

I see 1 Na on the left and 1 Na on the right.

1 see 1 Cl on the left and 1 on the right.

Everything checks.
