Question

Na>NaOH>Na2SO4>NaCL>Na

Answer 1

Ответ:

Объяснение:

1) 2Na + 2H2O = 2NaOH + H2

2) 2NaOH + H2SO4 = Na2SO4 + 2H2O

3) Na2SO4 +  BaCl2 = 2NaCl + BaSO4

4)2NaCl ( тут скорее всего электролизом, так как натрий металл активный) = 2Na + Cl2

Answer 2

It looks like you've provided a sequence of chemical compounds and elements, all containing sodium (Na), and arranged them in a specific order. This sequence appears to represent different chemical substances involving sodium. Let's break down this sequence:

1. Na: This represents elemental sodium, which is a pure element.

2. NaOH: This represents sodium hydroxide, also known as caustic soda. It's a strong base.

3. Na2SO4: This represents sodium sulfate, a salt commonly used in various industrial applications.

4. NaCl: This represents sodium chloride, which is common table salt.

It seems like you've arranged these substances based on some criteria. If you have a specific question or if you'd like more information about these substances and their properties or uses, please let me know, and I'd be happy to provide more details.
