Balance the following equation. then determine the mole ratio of ca(oh)2: akoh)3 az(so3+ ca(oh)2 akoh)3+ caso4?

The question is typed wrong. The correct question is

Balance the following equation. Then determine the mole ratio of Ca(OH)2:Al(OH)3.

Al2(SO4)3 + Ca(OH)2 --> Al(OH)3 + CaSO4

-

Al2(SO4)3 + 3 Ca(OH)2 = 2 Al(OH)3 + 3 CaSO4

3: 2

Explanation:-

Al2(SO4)3 + Ca(OH)2 --> Al(OH)3 + CaSO4

In the left hand side there are 3 S atoms from Al2(SO4)3

But in the right side there is only 1 S from CaSO4.

To make the right side same we multiply the CaSO4 by 3.

Al2(SO4)3 + Ca(OH)2 --> Al(OH)3 + 3 CaSO4

Now in the right side there 3 Ca from 3 CaSO4.

But in the left side there is only 1 Ca from Ca(OH)2.

To make it same we multiply Ca(OH)2 by 3.

Al2(SO4)3 + 3 Ca(OH)2 --> Al(OH)3 + 3 CaSO4

Now there 2 Al from Al2(SO4)3 on the left.

But there is only 1 Al from Al(OH)3.

So we multiply Al(OH)3 by 2.

Al2(SO4)3 + 3 Ca(OH)2 --> 2 Al(OH)3 + 3 CaSO4

Now we have 12 + 6 = 18 O on the left.

On the right we have 6 + 12 = 18 O atoms.

On the left we have 6 H atoms.

On the right we have 6 H atoms.

So our equation is balanced.

From the balanced equation

Al2(SO4)3 + 3 Ca(OH)2 --> 2 Al(OH)3 + 3 CaSO4

Ratio of Ca(OH)2 to Al(OH)3 = 3 : 2

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
