Question

Допоможіть будь ласка!!! ♥♥♥ Написати рівняння ряду перетворень і вказати тип реакції: 1. BaSO4→BaO→Ba(OH)2→BaCl2 2.P2O5→H3PO4→K3PO4

Answer 1

1)  BaSO4 -> BaO + SO3  разложение

    BaO + H2O = Ba(OH)2    соединение

    Ba(OH)2 + 2HCl = BaCl2 + 2H2O  обмен

2) P2O5 + 3H2O = 2H3PO4   соединение

  H3PO4 + 3KOH = K3PO4 + 3H2O  обмен

Answer 2

1. BaSO4 → BaO → Ba(OH)2 → BaCl2

The given series of transformations involves the compound BaSO4 being converted into BaO, then Ba(OH)2, and finally BaCl2. Let's analyze each step and determine the type of reaction involved.

Step 1: BaSO4 → BaO In this step, BaSO4 is converted into BaO. This transformation involves the removal of sulfur and oxygen from the compound. It is a reduction reaction, as the oxidation state of sulfur decreases from +6 in BaSO4 to 0 in BaO.

Step 2: BaO → Ba(OH)2 In this step, BaO is converted into Ba(OH)2. This transformation involves the addition of water molecules to BaO, resulting in the formation of a hydroxide compound. It is a hydration reaction.

Step 3: Ba(OH)2 → BaCl2 In this step, Ba(OH)2 is converted into BaCl2. This transformation involves the replacement of hydroxide ions with chloride ions. It is a double displacement reaction, specifically a neutralization reaction.

Therefore, the overall series of transformations involves a reduction reaction, a hydration reaction, and a double displacement reaction.

2. P2O5 → H3PO4 → K3PO4

The given series of transformations involves the compound P2O5 being converted into H3PO4, and then into K3PO4. Let's analyze each step and determine the type of reaction involved.

Step 1: P2O5 → H3PO4 In this step, P2O5 is converted into H3PO4. This transformation involves the addition of water molecules to P2O5, resulting in the formation of phosphoric acid. It is a hydration reaction.

Step 2: H3PO4 → K3PO4 In this step, H3PO4 is converted into K3PO4. This transformation involves the replacement of hydrogen ions with potassium ions. It is a double displacement reaction.

Therefore, the overall series of transformations involves a hydration reaction and a double displacement reaction.
