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

Answer:-

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
