Answer: Orbits are elliptical, Sun is in focal point of the ellipse.
Explanation:
Orbits are not perfect circles. Distance of Earth from Sun is between
147 million kilometres - 152 million kilometres. When Earth is in closest point of the Sun it moves faster tant in the point which is most far away from Sun.
Kepler´s Laws give more information.
Answer:
Presence of lone pairs of electrons
Explanation:
According to VSEPR theory, the presence of lone pairs caused increased repulsion of electron pairs on the valence shell of the centeral atom of the molecule. This decreases or distorts the bond angle. The decrease in bond ange depends on the number of lone pairs present on the valence shell of the central atom of the molecule. Ammonia has only one lone pair hence the bond angle is 107°, water has two lone pairs and the bond angle is 104°. Compare this this with the bond angle of 109° in methane which has only bond pairs and no lone pairs.
Answer:
the one in 20 degrees will take the longest to dissolve because it is coz meaning that the water particles do not have much movement to erode the sugar particles.
