Explanation:
According to Newton law of gravity, the strength of gravitational pull between two objects is related to their masses, directly, and inversely by the distance between them;
F = G * (M₂ – M₁) / d where;
F – the force of gravity
G – gravitational constant
M₂ – the mass of one object
M₁ – the mass of the other object
d – the distance between the two objects
The rocky planets have a higher mass than the gas planets hence will be strongly ‘feel’ the gravitational pull of the star in the solar system revolves about. This is why rocky planets are closer to their star while gas planets are towards the outer edges.

9L!!! You take the moles of N2 in the reaction and then divide by one mole of nitrogen. Then you multiply that by the number of hydrogen moles in the reaction which in this case is 3. This gives you an answer of 3. You then take the number of hydrogen moles and multiply it by the 3L giving you 9L of hydrogen.
No, not every collision makes a reaction.
Answer: Y 21.38 % , Al 32.44 % and O 46.16 %
Explanation: Molar mass of YAl5O12 is 88.91 + 5·26.98+12·16
= 415.81 g/mol
m-% ( Y) = 88.91 / 415.81 = 21.38 % , m-% (Al) = 5·26.98 / 415.81 =
32.44 % , rest is Oxygen
