Which molecule or compound below contains a nonpolar covalent bond? which molecule or compound below contains a nonpolar covalen
2 answers:
Answer: Option (b) is the correct answer.
Explanation:
A non-polar covalent bond is formed due to equal sharing of electrons between the combining atoms.
For example, is a non-polar covalent molecule.
Atomic number of nitrogen is 7 and its electronic distribution is 2, 5. So, a nitrogen atom needs three more electrons to attain stability. Hence, when it combines with three chlorine atoms then there occurs equal sharing of electrons.
Thus, we can conclude that compound has a non-polar covalent bond.

Answer:
The forward reaction is occurring at a faster rate than the reverse reaction.
Explanation:
Reaction quotient (Q) of the given reaction is -
where [NO], and
represents concentrations of respective species at a certain time.
Here = 0.80 M,
= 0.050 M and [NO] = 0.10 M
So,
Hence
It means that forward reaction is faster than reverse reaction at that point. Because then only concentration of NO is higher than concentrations of and
which makes Q higher than K.
