### Reaction and Heat Release Calculation

**Chemical Reaction:**

\[ 2X + Y_2Z_3 \rightarrow 2Y + X_2Z_3 \]

**Change in Enthalpy (\(\Delta H\)):**  
\[ \Delta H = -325 \, \text{kJ/mol} \]

**Problem Statement:**

Given the equation above, determine **how many kilojoules of heat are released** when 2.09 moles of Y are created.

**Calculation Steps:**  
To find the heat released when 2.09 moles of Y are produced, given that the reaction produces 2 moles of Y and releases 325 kJ of heat:

1. First, note that the production of 2 moles of Y releases 325 kJ.
2. Calculate the heat released per mole of Y:
   \[ \text{Heat per mole of } Y = \frac{325 \, \text{kJ}}{2} \]
3. Multiply this value by 2.09 to find the total heat released for 2.09 moles of Y.

This will give you the amount of heat released in kilojoules.
