# What does the reaction of CO2(g) + H2O(l) produce?

## I know that CO2(g) + H2O(l) --> H2CO3(aq), but I was wondering how to get there.

#### Explanation:

Step 1.

The δ^"-" oxygen in a water molecule attacks the δ^"+" carbon in a ${\text{CO}}_{2}$ molecule.

Step 2.

A second water molecule deprotonates the newly-formed oxonium ion.

Step 3

The newly formed hydronium ion transfers a proton to the negatively-charged oxygen atom that was formed in the first step.
