Bromine (Br2) being more reactive than Phosphorus displaces Phosphorus from Calcium phosphide (Ca3P2) to form Calcium bromide (CaBr2) and elemental phosphorus (P4) as shown
This is the single replacement reaction as the more reactive element (Bromine) displaces the less reactive element (Phosphorus) from its compound.
So the name of the element is Phosphorus.

Identify each of the following reactions as synthesis, decomposition, combustion, single replacement, or double replacement. If the reaction is a single or double replacement reaction, tell if the reaction occurs spontaneously. If the reaction does not occur spontaneously, write "No Reaction." If the reaction does occur spontaneously for single and double replacement write a balanced molecular, total ionic, and net ionic equation. For the other types of reactions, write a balanced chemical equation. 2. Water and dinitrogen trioxide gas 3....
