Question

When H20 (1) reacts with CO2(g) it gives
(1) HCO3 (aq)
2 H2CO3(aq)
(3) H2CO2 (aq)
(4) H2CO3 (aq)​

Answer 1

Answer:

H2CO3 (Carbonic Acid)

Explanation:

Bicarbonate is naturally produced by the reaction of carbon dioxide (CO2) with water. (H2O) to produce carbonic acid (H2CO3), which dissociates to a bicarbonate ion and a. proton (H. + ).

Answer 2

Answer:

(4) H2CO3 (aq)

Explanation:

This happens as the carbon dioxide forms acidic carbonic acid when it dissolves in the water, the carbonic acid (H2CO3) reacts further with the calcium carbonate: CO2 + H2O ——> H2CO3H2CO3 +CaCO3 ——–> Ca(HCO3)2 Ca(HCO3)2 = calcium hydrogen carbonate which is soluble in water.
