Answer 1

А1. С какими из перечисленных веществ будет реагировать оксид натрия?
4) H2O

Na2O + H2O = 2NaOH

Answer 2

Reactivity of Sodium Oxide (Na2O)

Sodium oxide (Na2O) is likely to react with water (H2O) from the given list of substances. When sodium oxide reacts with water, it forms sodium hydroxide (NaOH).

This information is supported by chemical reactions and properties of sodium oxide as a basic oxide. Sodium oxide is a basic oxide, and it reacts with water to form a strong base, sodium hydroxide.

Source: - "1) NO 2) NaCl 3) H2 4) H2O"

Conclusion

Sodium oxide (Na2O) is expected to react with water (H2O) from the provided list of substances.
