Question

Using the activity series, the reaction 2Al+6HBr-2 AlBr3+3 H2 will only occur if.....Al is above Be on the periodic table or heat is added to the reaction or a precipitate forms or Al is above H on the activity series

Answer 1

Answer:

Al is above H on the activity series

Explanation:

The given chemical reaction is expressed as:

            2Al + 6HBr →  2AlBr₃ +  3H₂

The reaction above is a single displacement or replacement reaction and will only occur if Al is above H on the activity series.

• The driving mechanism of such reaction is the position of the species on the activity series.
• The higher an atom is the more reactive and easier it will displace the lower ones.
