What Reaction type is CO2(g) + H2O() — H2CO3(aq)

Explanation:

this is a decomposition reaction because here a compound is broken into two two parts.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
