Question

написати рівняння хімічних реакцій за схемою зазначити типи реакцій BaCl2+H2SO4➖. BaO+SO3➖. Ba(OH)2+CuCl2➖​

Answer 1

Відповідь:

ВаСІ2+H2SO4=BaSO4+2HCI

BaO+SO3= BaSO4

Ba(OH)2+CuCl2= BaCI2+ Cu(OH)2

Пояснення:

Answer 2

Ответ:

BaCl2  + H2SO4  = BaSO4  + 2 HCl реакция обмена

SO3 + BaO = BaSO4 синтез (соединение)

CuCl2 + Ba(OH)2 = Cu(OH)2 + BaCl2 реакция обмена

Answer 3

Chemical Equations and Reaction Types

Here are the balanced chemical equations for the given reactions along with their reaction types:

1. BaCl2 + H2SO4 ➡️ BaO + SO3 - Reaction type: Double displacement reaction

2. BaO + SO3 ➡️ Ba(OH)2 + CuCl2 - Reaction type: Double displacement reaction

Let's balance the equations and discuss the reaction types in more detail.

Reaction 1: BaCl2 + H2SO4 ➡️ BaO + SO3

To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

The balanced equation is:

BaCl2 + H2SO4 ➡️ BaO + SO3

Reaction type: Double displacement reaction

In this reaction, barium chloride (BaCl2) reacts with sulfuric acid (H2SO4) to form barium oxide (BaO) and sulfur trioxide (SO3). This is a double displacement reaction, also known as a metathesis reaction. In a double displacement reaction, the positive ions of two compounds exchange places to form two new compounds.

Reaction 2: BaO + SO3 ➡️ Ba(OH)2 + CuCl2

To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

The balanced equation is:

BaO + SO3 ➡️ Ba(OH)2 + CuCl2

Reaction type: Double displacement reaction

In this reaction, barium oxide (BaO) reacts with sulfur trioxide (SO3) to form barium hydroxide (Ba(OH)2) and copper(II) chloride (CuCl2). This is also a double displacement reaction.
