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)

$\epsilon = \frac{c}{a}$

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

A reaction that occurs in the internal combustion engine is N₂(g) + O₂(g) ⇄ 2NO(g) (c) What is the significance of the different

vodomira [7]

The response would become spontaneous if the value of ΔG° was negative.

According to the estimated value of ΔG°, it is shown that ΔG° value decreases as temperature value increases. The value shifts from being more favorable to being less favorable. It would appear that the value of ΔG° would be negative at a specific temperature, causing the reaction to occur spontaneously.

The reaction is in an equilibrium state if ΔG = 0. If ΔG < 0, the reaction is spontaneous in the direction written. The relationship between terms from the equilibrium is paralleled by the relevance of the sign of a change in the Gibbs free energy.

Write the balanced chemical equation for the reverse reaction. include physical states for all species.

Ann [662]

This is a missing part of your question:
The equilibrium system between sulfur dioxide gas, oxygen gas, and sulfur trioxide gas is given.
So you need the equilibrium balanced equation of SO2, O2, SO3 reaction:
First, we will start with the original equation which is not balanced yet (to understand how we get it):
SO2 + O2 ↔ SO3
Here the number of O atom is not equal at the to sides
So we will start to balance our equation by make the number of O atom equal each other on both sides:
So we will start to put 2SO3 instead of SO3
and put 2SO2 instead of SO2 to balance also the S atom on both sides
So we will get this:
2SO2(g) + O2(g) ↔ 2SO3(g) (This is our equilibrium balanced equation)
know we have a number of O atom equals on each side = 6
and the sulfur equals on each side = 2
