Question

Na-naoh-nacl-naoh-na=

Answer 1

1. Na + 2H₂O = 2NaOH + H₂ ↑
2. NaOH + HCl = NaCl + H₂O
3. NaCl + H₂O = NaOH + HCl
4. NaOH + Li = LiOH + Na

Answer 2

The given sequence "Na-NAOH-NaCl-NAOH-Na" appears to be a combination of chemical symbols and compounds. Each part represents a chemical species or compound. Here's the breakdown:

1. Na: The chemical symbol for sodium.
2. NAOH: The chemical formula for sodium hydroxide, which is a strong base.
3. NaCl: The chemical formula for sodium chloride, commonly known as table salt.
4. NAOH: Again, sodium hydroxide.
5. Na: Sodium.

It seems like a mixture of sodium hydroxide (NaOH) and sodium chloride (NaCl) with sodium (Na) present at the beginning and end.
