**Answer:**

0.189 g

**Explanation:**

**Step 1: Write the balanced equation**

NCl₃ + 3 H₂O ⇒ NH₃ + 3 HCIO

**Step 2: Calculate the moles corresponding to 1.33 g of NCl₃**

The molar mass of NCl₃ is 120.36 g/mol.

1.33 g × 1 mol/120.36 g = 0.0111 mol

**Step 3: Calculate the moles of NH₃ produced from 0.0111 moles of NCl₃**

The molar ratio of NCl₃ to NH₃ is 1:1. The moles of NH₃ produced are 1/1 × 0.0111 mol = 0.0111 mol.

**Step 4: Calculate the mass corresponding to 0.0111 moles of NH₃**

The molar mass of NH₃ is 17.03 g/mol.

0.0111 mol × 17.03 g/mol = 0.189 g

**Answer:**

The energy of the photon is 1.718×10−26J.

**Explanation:**

The energy of the photon is

1.718 × 10 − 26J. You use the formula E =, where h is Planck's Constant,c is the speed of light, and λ is the wavelength of the photon.

E== = 1.718×10−26J.

<h3><u>Answer;</u></h3>

= 3032.15 kPa

<h3><u>Explanation;</u></h3>

Using the equation;

PV = nRT , where P is the pressure,. V is the volume, n is the number of moles and T is the temperature and R is the gas constant, 0.08206 L. atm. mol−1.

Volume = 7.5 L, T = 274 +273 = 547 K, N = 5 moles

Therefore;

Pressure = nRT/V

= (5 × 0.08206 × 547)/7.5 L

= 29.925 atm

But; 1 atm = 101325 pascals

Hence; Pressure = 3032150.63 pascals

**<u>= 3032.15 kPa</u>**
