what is the balanced equation for MgSO4+NH4OH-->Mg(OH)2 + (NH4)2SO4
I would start by noticing the the Mg and SO4 are already balanced on each side, and start with NH4.
Do you see what you can do to balance the NH4?
You start off the balancing by seeing which compounds of the equation are balanced. Mg and SO4 are balanced so find the other compounds that aren't balanced, the OH and the NH4.
There are 8 NH4 on the right side of the equation and the left side of the equation has 4 NH4 if you multiply NH4OH by 2 you will have 8 NH4 and 2 OH so you now have NH4 balanced on both sides. Now look at OH there are 2 OH on the left side and 2 OH on the right side so your equation is now balanced and you have: MgSO4 +2NH4OH--> Mg(OH)2 + (NH4)2SO4. Hope this helped :)
