Give examples of the following chemical equations: 1) basic oxide + water = alkali 2) Basic oxide + strong acid = salt + water 3) acid oxide + water = acid 4) acid oxide + alkali = salt + water

Let’s compose the equations according to the condition of the task:
1. Li2O + H2O = 2LiOH – compounds, obtained lithium hydroxide;
2. K2O + H2SO4 = K2SO4 + H2O – ion exchange, potassium sulfate, water is released;
3. SO3 + H2O = H2SO4 – compounds, sulfuric acid is formed;
4. СО2 + 2NaOH = Na2CO3 + H2O – ion exchange, obtained sodium carbonate, water.
These examples confirm the characteristic chemical properties of the oxides.
The reaction products – alkali, acid, salts – find practical application, for example, sodium carbonate is used in the composition of building mixtures.
