Question

1) Fe(NO3)2 + Ba(OH)2​

Answer 1

Молекулярное уравнение: Fe(NO3)2 + Ba(OH)2 ⇒ Fe(OH)2↓+Ba(NO3)2

Объяснение:

Answer 2

The reaction between Fe(NO3)2 and Ba(OH)2 is a double displacement reaction, also known as a precipitation reaction. It can be represented by the following balanced chemical equation:

Fe(NO3)2 + Ba(OH)2 → Ba(NO3)2 + Fe(OH)2

In this reaction, Fe(NO3)2 (iron(II) nitrate) reacts with Ba(OH)2 (barium hydroxide) to produce Ba(NO3)2 (barium nitrate) and Fe(OH)2 (iron(II) hydroxide).

Note that the balanced equation provided assumes complete reaction and the products are in their simplest ratio. In reality, iron(II) hydroxide is not stable and tends to oxidize to iron(III) hydroxide (Fe(OH)3) upon exposure to air.
