Explanation:
A molecular compound is defined as the compound in which atoms come closer to each other through sharing of electrons and results in the formation of covalent bond.
These compounds usually contain two or more number of non-metals.
Greek prefixes like mono, di, tri, tetra etc are used while naming molecular compounds as these prefixes indicate the number of atoms of each element present.
For example, 
is a molecular compound and its name is dichlorine heptoxide.
As di means 2, and hepta means 7.
Thus, we can conclude that for molecular compounds we use Greek, numerical prefixes in the name.
A precipitate will be formed through the double displacement method in chemical reactions. The chemical equation would be:
Na2CO3 + AgNO3 ----> NaNO3 + Ag2CO3.
Balancing would result to:
<span>Na2CO3 + 2AgNO3 ----> 2NaNO3 (aq)+ Ag2CO3.
</span>
Ag2CO3 is the precipitate formed. It is yellow in color but due to the presence of elemental silver, it is a bit grayish.
Electrical energy !! i hope this helped :))
Answer:
The air that we breathe in enters the nose or mouth, flows through the throat (pharynx) and voice box (larynx) and enters the windpipe (trachea). The trachea divides into two hollow tubes called bronchi
