Answer 2

Reaction Resulting in Gas Formation:

1. The reaction between sodium sulfite (Na2SO3) and hydrochloric acid (HCl) results in the formation of sulfur dioxide gas (SO2) according to the following balanced chemical equation: ``` Na2SO3 + 2HCl -> 2NaCl + SO2 + H2O ``` The sulfur dioxide gas is released as a product of the reaction [[1]].

2. The reaction between barium chloride (BaCl2) and sodium sulfite (Na2SO3) also produces sulfur dioxide gas (SO2) as one of the products. The balanced chemical equation for this reaction is: ``` BaCl2 + Na2SO3 -> BaSO3 + 2NaCl ``` The sulfur dioxide gas is released during this reaction [[2]].

3. When sodium chloride (NaCl) reacts with silver nitrate (AgNO3), it forms silver chloride (AgCl) as a precipitate. No gas is released in this reaction. The balanced chemical equation for this reaction is: ``` NaCl + AgNO3 -> AgCl + NaNO3 ``` The silver chloride precipitates out of the solution as a solid [[3]].

Reaction Resulting in Precipitate Formation:

1. The reaction between ferric chloride (FeCl3) and potassium sulfate (K2SO4) results in the formation of a precipitate of ferric sulfate (Fe2(SO4)3). The balanced chemical equation for this reaction is: ``` FeCl3 + 3K2SO4 -> Fe2(SO4)3 + 6KCl ``` The ferric sulfate precipitates out of the solution as a solid [[4]].

2. The reaction between ferric nitrate (Fe(NO3)3) and potassium hydroxide (KOH) also produces a precipitate. In this case, the precipitate formed is ferric hydroxide (Fe(OH)3). The balanced chemical equation for this reaction is: ``` Fe(NO3)3 + 3KOH -> Fe(OH)3 + 3KNO3 ``` The ferric hydroxide precipitates out of the solution as a solid [[5]].

3. The reaction between ferrous hydroxide (Fe(OH)2) and hydrochloric acid (HCl) results in the formation of a precipitate of ferrous chloride (FeCl2). The balanced chemical equation for this reaction is: ``` Fe(OH)2 + 2HCl -> FeCl2 + 2H2O ``` The ferrous chloride precipitates out of the solution as a solid [[6]].
