Question

Напишите уравнения реакций, с помощью которых можно осуществить следующие превращенияа)Li→ Li2O→ LiOH→ LiCl; из Li в LiOH. изLi2O в LiClбNa→ Na2O2→ Na2O→ NaOH→ Na2SO4↓NaNO3

Answer 1

а)1. 4Li+O2=2Li2O

  2.  Li2O +H2O=2LiOH

 3. LiOH+HCl= LiCl+H2O

Answer 2

I will answer in detail. Write the equations of the reactions that can be used to perform the following transformations:

a) Li → Li2O → LiOH → LiCl; from Li to LiOH. from Li2O to LiCl

To obtain LiOH from Li, we can use the following reaction:

Li + H2O → LiOH + H2

This is a single displacement reaction, where Li replaces H in H2O and forms LiOH and H2 gas.

To obtain LiCl from Li2O, we can use the following reaction:

Li2O + 2HCl → 2LiCl + H2O

This is a double displacement reaction, where Li and H exchange places and form LiCl and H2O.

b) Na → Na2O2 → Na2O → NaOH → Na2SO4 ↓ NaNO3

To obtain Na2O2 from Na, we can use the following reaction:

2Na + O2 → Na2O2

This is a synthesis reaction, where Na and O2 combine to form Na2O2.

To obtain Na2O from Na2O2, we can use the following reaction:

Na2O2 + H2O → 2NaOH + H2O2

This is a decomposition reaction, where Na2O2 breaks down into NaOH and H2O2 in the presence of water.

To obtain NaOH from Na2O, we can use the following reaction:

Na2O + H2O → 2NaOH

This is a synthesis reaction, where Na2O and H2O react to form NaOH.

To obtain Na2SO4 from NaOH, we can use the following reaction:

2NaOH + H2SO4 → Na2SO4 + 2H2O

This is a double displacement reaction, where Na and H exchange places and form Na2SO4 and H2O.

To obtain NaNO3 from Na2SO4, we can use the following reaction:

Na2SO4 + 2HNO3 → 2NaNO3 + H2SO4

This is a double displacement reaction, where Na and H exchange places and form NaNO3 and H2SO4.

You can find more information about these reactions and their types in the web search results . I hope this helps.
