Identify A and B in following reaction:
`6Cl_2 + 6Ba(OH)_2 to A + B + 6H_2O` :

Options

A. `Ba(ClO_3)_2 , BaCl_2`
B. `BaCl_2 , HCl`
C. `BaO, BaCl_2`
D. `BaO , HCl`

Explanation

To identify A and B in the reaction `6Cl_2 + 6Ba(OH)_2 → A + B + 6H_2O`, we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are chlorine gas (Cl₂) and barium hydroxide (Ba(OH)₂).

### Step 2: Understand the Reaction
Chlorine gas is a strong oxidizing agent and can react with bases like barium hydroxide. The reaction typically involves the formation of barium salts and water.

### Step 3: Determine Possible Products
When chlorine reacts with barium hydroxide, it can form:
1. Barium chloride (BaCl₂)
2. Barium hypochlorite (Ba(ClO)₂) or barium chlorate (Ba(ClO₃)₂), depending on the reaction conditions.

### Step 4: Write the Balanced Equation
To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides. The products can be:
- A = Barium chloride (BaCl₂)
- B = Barium chlorate (Ba(ClO₃)₂)

Thus, the balanced equation will be:
`6Cl₂ + 6Ba(OH)₂ → 6BaCl₂ + 2Ba(ClO₃)₂ + 6H₂O`

### Step 5: Identify A and B
From the balanced equation:
- A = BaCl₂ (Barium chloride)
- B = Ba(ClO₃)₂ (Barium chlorate)

### Final Answer
A = Barium chloride (BaCl₂)
B = Barium chlorate (Ba(ClO₃)₂)
