B. `H_(3)PO_(2)`
C. `H_(3)PO_(4)`
D. `H_(3)PO_(3)`

Answer

To answer the question regarding the reaction of white phosphorus with nitric acid, we can break down the process step by step.

### Step 1: Identify the Reactants
White phosphorus (P4) is the reactant that we are considering. It is a molecular form of phosphorus that is highly reactive.

**Hint:** Remember that white phosphorus is often represented as P4 and is known for its reactivity, especially with oxidizing agents.

### Step 2: Reaction with Nitric Acid
When white phosphorus reacts with nitric acid (HNO3), it undergoes oxidation. Nitric acid is a strong oxidizing agent that can oxidize phosphorus to different oxidation states.

**Hint:** Consider the oxidation states of phosphorus and how nitric acid can change these states during the reaction.

### Step 3: Products of the Reaction
The reaction of white phosphorus with nitric acid primarily produces phosphoric acid (H3PO4) and nitrogen oxides (NO, NO2). The balanced reaction can be represented as follows:

\[ P_4 + 10 HNO_3 \rightarrow 4 H_3PO_4 + 10 NO_2 + 2 H_2O \]

**Hint:** Look for the common products formed when phosphorus reacts with nitric acid, especially focusing on the formation of phosphoric acid.

### Step 4: Conclusion
Thus, the main products of the reaction between white phosphorus and nitric acid are phosphoric acid and nitrogen oxides.

**Final Answer:** White phosphorus when reacts with nitric acid gives phosphoric acid (H3PO4) and nitrogen oxides (NO, NO2).
