Question

a) balance the equations
1)Al(OH) 3 Al 3 O 3 +H 2 O
2)Al2(SO4)3 + NaOH → Al(OH)3 + Na₂SO4​

Answer 1

Answer:

Here is the chemical equation.

Al2(SO4)3+NaOH=Al(OH)3+Na2SO4

First of all equal the no. of atoms on both side of the equation.

Reactants            =         Products  

Al            2           =              Al            1 X 2 = 2

SO4        3           =             SO4          1 X 3 =3  

Na      1 X 6 = 6   =              Na           2 X 3 =6

OH      1 X 6=6    =              OH           2 X 3 = 6  

Balanced equation:

Al2(SO4)3 + 6NaOH ------------->2Al(OH)3 + 3Na2SO4

Step-by-step explanation:

Answer 2

Answer:

1)2Al(OH)3 → Al2O3 + 3H2O

2)Al2(SO4)3 (aq) + 6 NaOH (aq) → 2 Al(OH)3 (s) + 3 Na2SO4 (aq)
