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

Options

A. `F_(3)Cl_(2)+ H_(2)`
B. `Cl_(2)+H_(2)`
C. `H_(2)+ClF_(3)`
D. `Cl_(2)+HF`

Answer

To identify A and B in the reaction `F2 + HCl → A + B`, we can analyze the reaction step by step.

### Step 1: Understand the Reactants
The reactants in the reaction are:
- **F2**: This is fluorine gas, a diatomic molecule consisting of two fluorine atoms.
- **HCl**: This is hydrogen chloride, a diatomic molecule consisting of one hydrogen atom and one chlorine atom.

### Step 2: Consider the Possible Products
When fluorine reacts with hydrogen chloride, it can lead to the formation of different products. The key products to consider are:
- Chlorine gas (Cl2)
- Hydrogen fluoride (HF)

### Step 3: Write the Balanced Reaction
The balanced reaction can be written as follows:
\[ F_2 + 2 HCl \rightarrow Cl_2 + 2 HF \]

### Step 4: Identify A and B
From the balanced equation:
- **A** is Cl2 (chlorine gas)
- **B** is HF (hydrogen fluoride)

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

### Final Answer
A = Cl2, B = HF
