Question

Strontium metal reacts with aluminum chlorate to produce strontium

Answer 1

Answer: single replacement reaction, $3Sr+2Al(ClO_3)_3\rightarrow 3Sr(ClO_3)_2+2Al$

Explanation:

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.

A general single displacement reaction can be represented as :

$XY+Z\rightarrow XZ+Y$

As strontium metal is added to aluminum chlorate , strontium being more reactive than aluminium, displaces aluminium atom its salt solution and lead to formation of strontium  chlorate and aluminum metal.

$3Sr+2Al(ClO_3)_3\rightarrow 3Sr(ClO_3)_2+2Al$
