Respuesta :

Answer:

Explanation:

Here, we want to get the names or formulas of the given hydrates

2) Copper (I) Sulfate pentahydrate

Penta means 5 and pentahydrate means there are 5 molecules of water of crystallization

We have the Copper (I) Sulfate as:

[tex]Cu_2SO_4[/tex]

With the pentahydrate, we have it as:

[tex]Cu_2SO_4.5H_2O[/tex]

7) As we can see here, the root compound is Sodium Chromate

The water of crstallization is 4 molecules

The name of the compound is thus:

Sodium Chromate tetrahydrate
