Drops of nitric acid reacts with `P_(4)O_(10)` to gives:

Options

A. `NO`
B. `NO_(2)`
C. `N_(2)O_(5)`
D. `HPO_(3)`

Answer

To solve the problem of what products are formed when drops of nitric acid (HNO3) react with phosphorus pentoxide (P4O10), we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are:
- Nitric acid (HNO3)
- Phosphorus pentoxide (P4O10)

### Step 2: Write the Reaction
When nitric acid reacts with phosphorus pentoxide, the reaction can be represented as:
\[ \text{HNO}_3 + \text{P}_4\text{O}_{10} \rightarrow \text{Products} \]

### Step 3: Determine the Products
From the video transcript, we know that the products formed are:
- Metaphosphoric acid (HPO3)
- Dinitrogen pentoxide (N2O5)

### Step 4: Write the Balanced Chemical Equation
To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. The balanced equation is:
\[ 4 \text{HNO}_3 + \text{P}_4\text{O}_{10} \rightarrow 4 \text{HPO}_3 + 2 \text{N}_2\text{O}_5 \]

### Step 5: Identify the Correct Options
From the products formed, we can evaluate the options:
- A: Nitrogen monoxide (NO) - Not formed
- B: Nitrogen dioxide (NO2) - Not formed
- C: Dinitrogen pentoxide (N2O5) - Formed
- D: Metaphosphoric acid (HPO3) - Formed

Thus, the correct answers are options C and D.

### Final Answer
The products formed when drops of nitric acid react with phosphorus pentoxide are:
- C: Dinitrogen pentoxide (N2O5)
- D: Metaphosphoric acid (HPO3)
