Which of the following explains why the Earth orbits the sun rather than the sun orbiting the Earth? A. Earth has much smaller mass, so the gravitational force accelerates the Earth much more than it accelerates the sun.
B. The force of Earths gravity pulling on the sun has a smaller magnitude than the force of the sun pulling on Earth.
C. While the Earth is pulled toward the sun with a gravitational force, the sun is not pulled toward the Earth be a gravitational force.
D. Even though the sun is pulled toward the Earth, the force is opposed by forces from the gravity of the planets.

A

Explanation:

because like people and earth,the forces acting on earth by people is negligible .

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂

i think it's 35 meters
