Question

Write formulas or names as appropriate for each of the following hydrates. 2. Copper(I) sulfate pentahydrate 7. Na2CrO4•4H2O 3. Potassium phosphate decahydrate 8. CuF2•2H2O 4. Calcium chloride hexahydrate 9. Sr(NO3)2•6H2O 5. Iron(III) nitrate nonahydrate 10. ZnSO4•7H2O

Answer 1

Step-by-step 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:

`Cu_2SO_4`

With the pentahydrate, we have it as:

`Cu_2SO_4.5H_2O`

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
