   Dichlorine trioxide reacts with alkalis to form corresponding chlorate and chloride salts. For example, with sodium hydroxide (NaOH):

   \[ \text{Cl}_2\text{O}_3 + 2 \, \text{NaOH} \rightarrow \text{NaClO}_2 + \text{NaCl} + \text{H}_2\text{O} \]

Example Calculation

Let's consider an example calculation involving the molar mass of dichlorine trioxide. 

Given:

• Atomic mass of chlorine (Cl) = 35.45 g/mol
• Atomic mass of oxygen (O) = 16.00 g/mol

The molecular formula of dichlorine trioxide is \( \text{Cl}_2\text{O}_3 \). To calculate its molar mass:

\[ \text{Molar mass of } \text{Cl}_2\text{O}_3 = (2 \times 35.45 \, \text{g/mol}) + (3 \times 16.00 \, \text{g/mol}) \]

\[ = 70.90 \, \text{g/mol} + 48.00 \, \text{g/mol} \]

\[ = 118.90 \, \text{g/mol} \]

Safety Considerations

Dichlorine trioxide is a reactive and potentially hazardous compound. Proper safety measures should be taken when handling it, including the use of personal protective equipment (PPE), working in a well-ventilated area, and adhering to relevant safety guidelines and regulations.
