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.
