Question

Даю 65 балов Осуществите переход Br2 - MgBr2 - Br2 - HBr - AlBr3

Answer 1

Br2 + Mg = MgBr2
MgBr2 +Cl2 = MgCl2 + Br2
Br2 + H2 = 2HBr
6HBr +2Al = 2AlBr3 + 3H2

Chemical Reaction Steps

To carry out the given chemical reaction, the following steps need to be followed:

1. Br2 to MgBr2: The reaction between Br2 and Mg produces MgBr2. 2. MgBr2 to Br2: The reverse reaction of MgBr2 decomposes it back into Br2 and Mg. 3. Br2 to HBr: The reaction of Br2 with H2 produces HBr. 4. HBr to AlBr3: The reaction between HBr and Al yields AlBr3.

Chemical Reaction Steps with Notation

1. Br2 to MgBr2: - The reaction between Br2 and Mg produces MgBr2. - This can be represented as: `Br2 + Mg → MgBr2`.

2. MgBr2 to Br2: - The reverse reaction of MgBr2 decomposes it back into Br2 and Mg. - This can be represented as: `MgBr2 → Br2 + Mg`.

3. Br2 to HBr: - The reaction of Br2 with H2 produces HBr. - This can be represented as: `Br2 + H2 → 2HBr`.

4. HBr to AlBr3: - The reaction between HBr and Al yields AlBr3. - This can be represented as: `6HBr + Al → 2AlBr3 + 3H2`.

By following these steps, the complete transformation from Br2 to AlBr3 can be achieved.
