2 answers:
The definition of eccentricity allows to find the correct answers are:
1. A. its orbit is a highly elongated ellipsis.
2. A. 0.9200
3. A. 0.0068
The eccentricity of an ellipse is defined as the relationship between the distance of the semi-major axis (a) and the distance from the center of the ellipse to one of the foci (c)
Where ε is the eccentricity, a and c are the distance to the major axis and the focus, respectively.
Eccentricity values range from ε = 0 for the circumference to ε = 1 to approximate a segment
They indicate several questions
1) What does it mean when the orbital eccentricity of a planet is close to 1?
Checking the answers, the correct one is:
A. its orbit is a highly elongated ellipsis.
2) Astronomers discover a new comet that follows a highly elliptical orbit. What is its eccentricity likely to be?
The answer is an eccentricity very close to 1, the correct answer is:
A. 0.9200
3)Venus has the smallest orbital eccentricity of any of the planets. What is the eccentricity of Venus?(1 point)
The planet Venus has an almost circular orbit of the times tabulated, its eccentricity is 0.0068
The correct answer is:
A. 0.0068
In conclusion, using the definition of eccentricity, we can find the correct answers to the questions:
1. The correct is : A. The orbit is a very elongated ellipse
2. The correct is: A. 0.9200
3. The correct is: A. 0.0068

Explanation:
Lone pairs are present on nitrogen atoms of both pyridine and pyrrole.
In pyrrole, the electron pair on nitrogen is involved in resonance and hence does not available for bonding. Therefore, pyrrole does not possess basic character and remains unreactive towards HCl.
In case of pyridine, as 6 pi electrons are present in the ring, so, electron pair of nitrogen does not participate in resonance. So, because of presence of lone pair, pyridine possess basic character and hence, reacts readily reacts with HCl.
