2NaCl + 2H2O → 2NaOH + Cl2 + CO2
Explanation:
In this reaction, sodium chloride (NaCl) undergoes a metathesis reaction with water (H2O). During the reaction, the sodium (Na) and chlorine (Cl) ions in NaCl exchange places with hydrogen (H) and hydroxide (OH) ions from water.
As a result, two molecules of sodium hydroxide (NaOH) are formed, along with one molecule of chlorine gas (Cl2) and one molecule of carbon dioxide (CO2). The equation is balanced to account for the conservation of mass and charge.
Please note that this reaction requires a source of energy, such as heat or an electric current, to proceed. Under normal conditions, NaCl and H2O do not react spontaneously to produce CO2.
