Question

Na2CO3 → BaCO3 → CO2

Answer 1

Ответ:

Na2CO3+BaCl2=BaCO3+2NaCl

BaCO3+2HCl=BaCl2+CO2+H2O

Answer 2

The chemical equation you provided represents a series of reactions involving sodium carbonate (Na2CO3) and barium carbonate (BaCO3) leading to the formation of carbon dioxide (CO2). Let's break down the reactions step by step:

1. Na2CO3 (sodium carbonate) reacts with BaCl2 (barium chloride) in an aqueous solution to form BaCO3 (barium carbonate) and NaCl (sodium chloride):

Na2CO3 + BaCl2 → BaCO3 + 2NaCl

2. Barium carbonate (BaCO3) decomposes upon heating, producing carbon dioxide (CO2) and barium oxide (BaO):

BaCO3 → BaO + CO2

So, the overall reaction can be summarized as:

Na2CO3 + BaCl2 → BaCO3 + 2NaCl BaCO3 → BaO + CO2
