Question

Na2O➡️NaOH➡️Na2So3➡️NaCL

Answer 1

Ответ:

Объяснение:

Na2O + H2O = 2NaOH

2NaOH + SO2 = Na2SO3 + H2O

Na2SO3 + 2HCl = 2NaCl+ SO2 + H2O

Answer 2

The given sequence of reactions involves the conversion of sodium oxide (Na2O) to sodium chloride (NaCl) via intermediate products of sodium hydroxide (NaOH) and sodium sulfite (Na2SO3). Here's a brief description of each step:

1. Na2O (sodium oxide) reacts with water (H2O) to produce NaOH (sodium hydroxide):

   Na2O + H2O → 2NaOH

2. NaOH (sodium hydroxide) reacts with sulfur dioxide (SO2) to produce Na2SO3 (sodium sulfite):

   2NaOH + SO2 → Na2SO3 + H2O

3. Na2SO3 (sodium sulfite) reacts with hydrochloric acid (HCl) to produce NaCl (sodium chloride):

   Na2SO3 + 2HCl → 2NaCl + SO2 + H2O

Overall, the complete reaction can be written as:

Copy code
Na2O + SO2 + 2H2O + 2HCl → 2NaCl + SO2 + 2H2O

Note that the sulfur dioxide is recycled in the second and third reactions, so it is not consumed in the overall reaction.
