Answer:
C.overlapping p orbitals
Explanation:
The atoms which comprises of single bond is formed by sigma bond. Sigma bond is formed by the internuclear overlapping of the atomic orbitals. They are formed due to the head on overlapping of the atomic orbitals. Since, the bond is symmetrical about the internuclear axis, it can rotate without the breakage of the bond.
On the other hand, double or triple bonds contains one or two pi bonds respectively along with one sigma bond. Pi bonds are formed by the sideways overlapping and thus they are non-symmetrical about the internuclear axis and thus it breaks if the bond is being rotated.
Thus the answer is:- C.overlapping p orbitals
Biosphere. it is a place where plant's and animals live together and they r interconnected to eachother
Explanation:
Nitrous acid is prepared in situ from hydrochloric acid and sodium nitrate because it is a weak acid and unstable. It only exists in an aqueous solution.
Nitrous acid is an unstable acid which gets decompose into the water , nitrogen dioxide and nitrogen monoxide gas.
Whereas nitric acid is highly stable acid which can be easily prepared from its reagent and it can easily be stored for future use.
Answer:
<u>Explanation</u>:
<u>Number of molecules for </u>
Atomic mass of Na + H + C + 3(O) = 22.99 + 1.008 + 12.01 + 3 × 16.00 = 84.00 g/mol
<u>Number of molecules for for </u>
= Atomic mass of 3(Na) + P + 4(O)
= 3(22.99) + 30.97 + 4(16.00) = 163.94 g/mol
