A single replacement reaction can be identified when there is a "single" element and a compound on each side of the chemical equation. For example:

#Al# + #CuCl_2# ---> #Cu# + #AlCl_3#

In this example,
On the left side, aluminum is the single element and copper chloride is the compound.

On the right side, copper is the single element and aluminum chloride is the compound.

Simply, the aluminum has replaced the copper in the compound.

Yes, the equation is not balanced.
