They all are correct , so with that being said anyone of them can be right
Answer:
(B) II, IV.
hope this answer is helpful for u.
Na2C03 is formed through the reaction of
NaOH and H2CO3 namely sodium hydroxide and carbonic acid
NaOH -> strong base
H2CO3-> weak acid
Answer is: in chemical reaction with with weak acid, sodium carbonate produce carbonic acid (H₂CO₃), which decomposes into carbon(IV) oxide (fizzy bubbles) and water.
Balanced chemical reaction:
Na₂CO₃ + 2HClO → CO₂(g) + H₂O + 2NaClO.
Chemical decomposition is the separation of a carbonic acid into water and carbon dioxide: H₂CO₃ → CO₂ + H₂O.
