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

To balance the reaction, we look at the number of atoms of each element we have. It should be equal for both sides. The balanced reaction is:

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

The ratio of calcium hydroxide and aluminum hydroxide is 3:2.

The differences are listed below.

Explanation:

A trivial explanation would be: those are different compounds belonging to different classes (categories) of chemical substances.

Let's look at several differences that these two compounds have:

calcium carbonate has a chemical formula of and calcium oxide has a chemical formula of ;calcium carbonate is considered to be a salt, while calcium oxide simply belongs to the class of basic (metallic) oxides;calcium carbonate is insoluble in water, it doesn't dissociate in water and doesn't react with it in any other way. In contrast, calcium oxide reacts with water to produce calcium hydroxide;calcium carbonate has a much lower melting point compared to calcium oxide. This is due to the fact that in CaO, calcium is bonded to a very small oxygen anion as opposed to a bulky carbonate anion in calcium carbonate. This yields a much greater Coulombic attraction force in CaO and a much higher melting point.another difference would simply be the fact that calcium carbonate consists of 3 different elements, calcium, carbon and oxygen, while CaO only consists of 2 different elements, calcium and oxygen.
