Answer:When a single compound breaks down into two or more compounds or elements in a chemical reaction then it is known as decomposition reaction.
The chemical symbol for sodium carbonate is .
The decomposition of sodium carbonate is:
The decomposition of sodium bicarbonate, will result in the formation of sodium oxide, and carbon dioxide, .
Hence, carbon dioxide, will produce with sodium oxide, on decomposition of .
Explanation:Na2CO3 Na2O +CO2 CO2 is the answer
Apple snails inhabit a wide range of ecosystems from swamps, ditches and ponds to lakes and rivers. The majority of the species prefer lentic water above streaming water and only a few species have adapted to rivers with strong current.

The lung/gills combination in apple snails reflects their adaptation to habitats with oxygen poor water. This is often the case in swamps and shallow waters. The without thelung they would completely depend on their gills, which would decrease their ability to survive.
Another advantage of air breathing in combination with a shell door (operculum) is the ability to survive periods of drought often common in these habitats during the dry season.
Hi , basically dominant alleles are always expressed in the organism , while recessive traits tend to be expressed only when the dominant allele is not present.
A valence bond is something used to explain chemical bonding. And as well a molecular orbital. So Two atoms that have unpaired electrons in their orbitals that overlap rises to give a chemical bond. So basically. The two atoms give each other's unpaired electron to form a filled orbital to make a hybrid orbital and for it to bond together.
