[tex] \textbf{Let's balance the given equation :} [/tex]
- [tex] \textsf{First, let's balance the } [/tex] [tex] \sf{\: SO_4} [/tex][tex] \textsf{molecule, multiply } [/tex][tex] \sf{ CaSO_4 } [/tex][tex] \textsf{by 3} [/tex]
- [tex] \textsf{now, let's balance the } [/tex] [tex] \sf{\: Ca} [/tex][tex] \textsf{atom, multiply } [/tex][tex] \sf{ Ca(OH)_4} [/tex][tex] \textsf{by 3} [/tex]
- [tex] \textsf{then, let's balance the } [/tex] [tex] \sf{\: Al} [/tex][tex] \textsf{atom, multiply } [/tex][tex] \sf{ Al(OH)_3 } [/tex][tex] \textsf{by 2} [/tex]
It's all balanced now ~
[tex] \sf{Al_2(SO_4)_3 + \boxed3 \: Ca(OH)_2 → \boxed2 \: Al(OH)_3 + \boxed3 \: CaSO_4}[/tex]
