Answer 1

Following is the - complete Answer -&- Explanation: for the :first two questions ( i.e. Question - 1 , and Question - 2 ), of the given: Question Set...in....typed format...

-----------------------------------------------------------------------------------

$\Rightarrow$Question - 1:

$\Rightarrow$Answer:

1. part - (a): Iron ( III ) phosphate: FePO₄ : INSOLUBLE ( i.e. in water )
2. part - (b): sodium carbonate : Na₂CO₃ : SOLUBLE ( i.e. in water )

$\Rightarrow$Explanation:

We can find the above Answers: from the solubility chart: of different cations: and anions...

$\Rightarrow$Question - 2:

$\Rightarrow$Answer:

  balanced chemical equation: Cu₃N₂ (aq.) + 3 (NH₄)₂SO₄ (aq) $\rightleftharpoons$ 2 (NH₄)₃N (s) + 3 CuSO₄ (aq)

$\Rightarrow$Explanation:

If we react the following: i.e.

1. Copper ( III ) Nitride : Cu₃N₂, aqueous
2. Ammonium sulfate ( aqueous ) :  (NH₄)₂SO₄
3. Ammonium Nitride ( aqueous ) :  (NH₄ )₃N
4. Copper (II) sulfate :  CuSO₄

​​​​​​​We will get the following balanced chemical equation:

$\Rightarrow$Cu₃N₂ (aq.) + 3 (NH₄)₂SO₄ (aq) $\rightleftharpoons$ 2 (NH₄)₃N (s) + 3 CuSO₄ (aq)
