Answer: C. The orbital speeds of planets closer to the Sun will be faster than planets farther away.
Explanation:
Centripetal force = gravitational force
Fg inversely proportional to distances (r)
because the value of the gravitational force is getting smaller as the distance is getting further from the sun, the orbital speed of the planet will be getting smaller
The ratio of N₂ to hydrogen is 1:3
so if N₂ is 2 then hydrogen will be six
2:6.
6 moles
First, you need to be given the gram formula mass of this molecular or related conditions that can calculate this. Then you need the empirical formula and calculate the gram formula mass of empirical formula. Then use them to get the ratio. Finally you can get the molecular formula.
