Identify A and B in the following reaction:
`I_(2) + HCl rarr A+B`

Options

A. `H_(2)+Cl_(2)`
B. `Cl_(2)+HI`
C. `HI+ICl_(3)`
D. `ICl_(3)+H_(2)`

Answer

To solve the reaction of iodine (I₂) with hydrogen chloride (HCl) and identify the products A and B, we can follow these steps:

### Step 1: Write the Reactants
The reactants in the reaction are iodine (I₂) and hydrogen chloride (HCl).

### Step 2: Understand the Reaction
When iodine reacts with hydrogen chloride, it undergoes a chemical reaction. We need to determine what products are formed from this reaction.

### Step 3: Identify Possible Products
From the knowledge of halogen reactions, we know that iodine can react with hydrogen chloride to produce hydrogen iodide (HI) and chlorine gas (Cl₂).

### Step 4: Write the Balanced Chemical Equation
The balanced chemical equation for the reaction is:
\[ I_2 + 2HCl \rightarrow Cl_2 + 2HI \]

### Step 5: Identify Products A and B
From the balanced equation:
- Product A is chlorine gas (Cl₂).
- Product B is hydrogen iodide (HI).

### Conclusion
Thus, the products of the reaction are:
- A = Cl₂
- B = HI

The correct answer is:
**Cl₂ and HI**
