Question

¦ Na-NaOH-Na2SO4BaSO4 ¦ Na2O–NaOH-Cu(OH)2+Cuo​

Answer 1

Ответ:

Объяснение:

2Na + 2H2O = 2NaOH + H2↑

2NaOH + H2SO4 = Na2SO4 + 2H2O

Na2SO4 + BaCl2 = BaSO4↓ + 2NaCl

4Na + O2 = 2Na2O

Na2O + H2O = 2NaOH

2NaOH + CuCl2 = Cu(OH)2↓ + 2NaCl

Cu(OH)2 -> CuO + H2O

Answer 2

It seems like you've provided a series of chemical reactions or equations. These reactions involve various chemical compounds. Let me break down each reaction for you:

1. Na - NaOH - Na2SO4 - BaSO4:

   • This sequence of reactions involves the transformation of sodium (Na) into sodium hydroxide (NaOH) and then into sodium sulfate (Na2SO4). Finally, sodium sulfate reacts with barium chloride (BaSO4) to form barium sulfate (BaSO4).

2. Na2O - NaOH - Cu(OH)2 + CuO:

   • In this sequence of reactions, sodium oxide (Na2O) reacts with sodium hydroxide (NaOH) to form copper(II) hydroxide (Cu(OH)2) and copper(II) oxide (CuO).

If you have any specific questions or need further information about these reactions or any other chemistry-related topic, please feel free to ask.
