Answer:

The two observations we made from viewing the solar system model are as follows as:

1). When we look at the sky we observe that the motions of all the planets and the stars are perfect circular movements with a good and high speed, but not in velocity because in velocity direction doesn't charges.

2). The sun is at the centre of our solar system and all the planets are equidistant to each other planets and also revolve around the sun.

How many hydrogen atoms are in a cycloalkane with 8 carbon atoms?
frosja888 [35]
Cycloalkanes are those saturated organic compounds which exist in the form of Rings. Their Hydrogen Deficiency Index in one. The General formula for cycloalkanes is,
                                                  CnH2n
When number of Carbons = 8
Then
                                                  C₈H₂₍₈₎

                                                  C₈H₁₆

Result:
           
Cycloalkane containing 8 carbon atoms has 16 hydrogen atoms.
