Question

carbon dioxide gas reacts with liquid water to produce aqueous carbonic acid. which chemical equation correctly translates the description above?
a co₂(l) + h₂o(l) → h₂co₃(aq)
b co₂(g) + h₂o(l) → h₂co₃(aq)
c co₂(s) + h₂o(g) → h₂co₃(s)
d co₂(l) + h₂o(l) → h₂co₃(l)
e co₂(g) + h₂o(g) → h₂co₃(aq)

Explanation:

Step1: Analyze the states of reactants

Carbon dioxide is a gas (\(CO_2(g)\)), water is a liquid (\(H_2O(l)\)).

Step2: Analyze the state of product

Carbonic acid is in aqueous solution (\(H_2CO_3(aq)\)).

Step3: Write the correct equation

The correct chemical equation is \(CO_2(g)+H_2O(l)\to H_2CO_3(aq)\).

Answer:

B. \(CO_2(g)+H_2O(l)\to H_2CO_3(aq)\)
