Question

Sodium carbonate + hydrochloric acid → sodium chloride + water + carbon dioxide↑
i. Which phenomenon is observed in the above reaction?​

Answer 1

Answer:

double displacement reaction

double displacement reactionWhen solutions of sodium carbonate and hydrochloric acid are mixed, the equation for the hypothetical double displacement reaction is: Na2CO3 + 2 HCl → 2 NaCl + H2CO3 Bubbles of a colorless gas are evolved when these solutions are mixed.

Answer 2

Answer:

Sodium carbonate+ hydrochloric acid ➡️ Sodium chloride+ water+ carbon dioxide

Na2 + HCL ➡️ Nacl + H2O ± CO2

It's a double displacement reaction .
