Calcium Carbonate Hexahydrate
(Ca C O3 6H20)

The number you would write before water in the formula for calcium carbonate hexahydrate would be 6.


Facts about Calcium Carbonate Hexahydrate:
<span>This compound often crystallises when Essex river waters are softened by the lime/soda process. Formation of the hydrated salt is favoured by low water temperatures and by high orthophosphate levels. Calcium carbonate hexahydrate forms pure well-defined crystals which are considerably more soluble in water than calcite, the usual product of lime/soda softening. </span>

2zns(s)+3o2(g)—&gt;2zno(s)+2so2(g)
Paha777 [63]

This is an example of displacement reaction

<u>Explanation:</u>

  • The chemical reaction in which the one element replaces the other element in a compound is called a displacement reaction. This reaction is also called a replacement reaction.

                                AB + C -----> AC +B

                        2ZnS + 3O2 -----> 2ZnO + 2SO2

  • This happens when A is more reactive than B and gives a stable product. Here the zinc sulfide compound reacts with the oxygen element to the stable product of zinc oxide and sulfur dioxide.
  • In short, the more reactive element displaces the less reactive element is called a displacement reaction.

When an ionic compound dissolves in water: When an ionic compound dissolves in water: the solvent-solute attractive forces overc
oksano4ka [1.4K]

Answer:

each of the above (A, B, and C) occurs

Explanation:

When an ionic compound dissolves in the water, the following happens :

-- the solvent solute attractive forces tries to overcome the solute solute attractions.

-- the water dipoles' negative end attracts the positive ions

--  the water dipoles' positive end attracts the negative ions

For example,

NaCl which is an ionic compound and also a strong electrolyte, it dissociates into water on the hydrated Na cations as well as Cl anions.

In water, the oxygen has negative charge and thus attracts the positive ions of the sodium, whereas the hydrogen is of positive and it attract the ions of chlorine which is negative.
