Question

Al2O3+X=Al2（SO4)3+3H2O?

Answer 1

X= H2SO4
Al2O3+3 H2SO4 --->Al2（SO4)3+3H2O

Answer 2

The chemical equation you provided is not balanced. To balance it, we need to make sure that the same number of each type of atom is present on both sides of the equation. Let's balance the equation step by step.

The unbalanced equation is:

Al2O3 + X = Al2(SO4)3 + 3H2O

Step 1: Balance the Al (aluminum) atoms: There are 2 Al atoms on the left side and 2 Al atoms on the right side, so this is already balanced for Al.

Step 2: Balance the O (oxygen) atoms: There are 3 O atoms in Al2O3 and 12 O atoms in Al2(SO4)3. To balance the oxygen atoms, we need to add 9 O atoms on the left side.

Al2O3 + 9O2 = Al2(SO4)3 + 3H2O

Step 3: Balance the H (hydrogen) atoms: There are 6 H atoms on the right side (3 H2O molecules), so we need to add 6 H atoms on the left side.

Al2O3 + 9O2 + 6H2 = Al2(SO4)3 + 3H2O

Step 4: Balance the S (sulfur) atoms: There are 3 S atoms in Al2(SO4)3, so we need to add 3 S atoms on the left side.

Al2O3 + 9O2 + 6H2 + 3S = Al2(SO4)3 + 3H2O

Now the equation is balanced with respect to all atoms. The final balanced equation is:

2Al2O3 + 9O2 + 6H2 + 3S = Al2(SO4)3 + 3H2O
