Question

How do you balance `NH_4OH + FeCl_3 -> Fe(OH)_3 + NH_4Cl`?

Answer 1

Trial method may be done as follows

Explanation:

In LHS you have 3 Cl, to balance you are to take 3 before `NH_4Cl` in RHS, Now you are to write 3 before `NH_4OH`in LHS and it will be balanced
This becomes
`3NH_4OH+FeCl_3=Fe(OH)_3 +3NH_4Cl`
