I learnt this one in school at the age of 11 years.
CaCO3(s) ===heat===> CaO(s) + CO2(g)
Is the thermal decomposition of calcium carbonate.
You need to heat the Calcium carbonate to 'red' heat (1000 oC). where upon CO2 is liberated.
In an experiment you can not see any change in calcium carbonate (CacO3) is white in colour as is Calcium Oxide (CaO). The two ways to check for the liberation of CO2 is :-
When cooled the residue solid(CaO) should weigh less, then before the experiment. or
Collect the liberated CO2 and bubble through lime water; it turns 'milky' in colour.
SO2 plus H2O equals H2SO3 which is Sulfurous Acid. CO2 plus H2O equals H2CO3which is Carbonic Acid. It also forms HNO3 which is nitric acid.
The chemical equation for Carbonic Acid is H2CO3.
This equation is Ca + H2CO3 => CaCO3 + H2.
When sulfurous acid reacts with lithium hydroxide, it forms lithium sulfite and water. The balanced chemical equation for the reaction is: H2SO3 + 2LiOH -> Li2SO3 + 2H2O.
The reaction between magnesium carbonate and nitric acid involves both a double displacement reaction, where magnesium carbonate and nitric acid switch partners to form magnesium nitrate and carbonic acid, and a decomposition reaction, where carbonic acid breaks down into water and carbon dioxide.

The chemical equation for Carbonic Acid is H2CO3.
This equation is Ca + H2CO3 => CaCO3 + H2.
It forms Carbonic Acid and this is a decomposition reaction

H2CO3 is Carbonic Acid or HCO3- is Bicarbonate
Carbonic acid comes from the reaction of carbon dioxide with water or with water vapor in the air. Here's the equation: CO2 + H2O => H2CO3
The balanced equation for potassium oxide (K2O) reacting with carbonic acid (H2CO3) is: K2O + H2CO3 -> 2KOH + CO2
Dihydrogen Sulfur Trioxide or sulfurous acid
H2SO4 is the chemical formula of sulphuric acid.
Sulfurous acid has the chemical formula H2SO3, while sulfuric acid has the chemical formula H2SO4. Sulfurous acid can be oxidized to sulfuric acid by adding an oxidizing agent, such as hydrogen peroxide or nitric acid. This oxidation process converts the sulfur atom in sulfurous acid from a +4 oxidation state to a +6 oxidation state, resulting in the formation of sulfuric acid.
