### Step-by-Step Solution: **(a)** When white phosphorus (P₄) is heated with concentrated sodium hydroxide (NaOH) solution in an inert atmosphere of carbon dioxide (CO₂), a chemical reaction occurs that produces phosphine (PH₃) and sodium hypophosphite (NaH₂PO₂). The balanced chemical equation for this reaction is: \[ P_4 + 3 \text{NaOH} + 3 \text{H}_2\text{O} \rightarrow 3 \text{PH}_3 + 3 \text{NaH}_2\text{PO}_2 \] ...
