Answer:
(B) Resonance will be a stabilizing factor.
(D) Charge is delocalized over several atoms.
Explanation:
Hello!
Resonance theory attempts to explain certain experimental data observed. Molecules such as benzene cannot be explained by previous theories because the experimental data does not match, for example, the link length is intermediate between a single and a double bond in said molecule.
Resonance theory explains the additional stability of certain molecules from the delocalization of electrons between several atoms.

anong sagot jan? d ko kasi alam ehhh penge sagot
Answer:
80 m/s.
Explanation:
NOTE: This is a physics question. However, the solution to the question given below:
From the question given above, the following data were obtained:
Acceleration (a) = 2 m/s²
Initial velocity (u) = 20 m/s
Time (t) = 30 s
Final velocity (v) =?
The final velocity of the train can be obtained as shown below:
v = u + at
v = 20 + (2 × 30)
v = 20 + 60
v = 80 m/s
Therefore, the final velocity of train is 80 m/s.
Answer:
- contains oxygen
- provides warmth
- blocks harmful energy from the Sun
Explanation:
The atmosphere is crucial when it comes to providing living conditions on Earth. The gases in the atmosphere manage to balance the things just about right, so that the life can thrive. The atmosphere has oxygen, the gas that is used by pretty much every organism to be able to function. With its greenhouse gases, the atmosphere manages to trap the heat inside, thus providing warmth to the Earth. The numerous layers of the atmosphere manage to block in big portion the harmful energy from the Sun, with a special accent on the ozone layer, a layer that manages to stop most of the UV radiation.
