The total number of moles of chlorine gas evolved is:

Options

A. `(0.5)`
B. `(1.0)`
C. `(2.0)`
D. `(3.0)`

Explanation

To determine the total number of moles of chlorine gas evolved from the dissociation of sodium chloride (NaCl), we can follow these steps:

### Step 1: Write the Dissociation Reaction
The dissociation of sodium chloride in water can be represented as:
\[ \text{NaCl (s)} \rightarrow \text{Na}^+ (aq) + \text{Cl}^- (aq) \]

### Step 2: Identify the Electrochemical Reaction
At the anode during electrolysis, the chloride ions (Cl^-) are oxidized to form chlorine gas (Cl2). The half-reaction for this process is:
...
