Co²+NaOH

The chemical equation for the reaction between carbon dioxide (CO2) and sodium hydroxide (NaOH) is as follows:

CO2 + 2NaOH -> Na2CO3 + H2O

In this reaction, carbon dioxide reacts with sodium hydroxide to produce sodium carbonate (Na2CO3) and water (H2O). The reaction is a neutralization reaction, where CO2 acts as an acid and NaOH acts as a base.

To balance the equation, we need to ensure that the number of atoms on both sides of the equation is the same. In this case, we have one carbon atom, two oxygen atoms, two hydrogen atoms, one sodium atom, and one oxygen atom.

The balanced equation is:

CO2 + 2NaOH -> Na2CO3 + H2O
